In a first aspect, an embodiment of the present disclosure provides a command distribution apparatus, including at least one distribution circuit and at least one information buffer; wherein each of the distribution circuits is connected to the at least one information buffer. Each of the information buffers in the at least one information buffer is used to store the number of currently unprocessed commands in the corresponding operation unit as the number of commands and the command number threshold of the corresponding operation unit. Each distribution circuit in the at least one distribution circuit is used to read the first command currently to be sent from the command queue corresponding to the distribution circuit, based on the arithmetic unit identifier carried in the first command, from the The number of commands and the threshold of the number of commands are read from the first information buffer corresponding to the identification of the arithmetic unit; in response to the number of commands meeting a preset condition, an arbitration request signal is sent to the arbitration circuit.

In this way, each distribution circuit in the command distribution device will send an arbitration request signal to the arbitration circuit only when the number of commands satisfies the preset condition. Therefore, it is possible to avoid command accumulation in some operation units and no executable in other operation units. In the case of a command, the execution efficiency of the command is improved, and the computing resource utilization of the computing unit is increased.

In addition, when the number of commands does not meet the preset conditions, each distribution circuit will not participate in the authority arbitration process, and will not occupy the bus; and the distribution circuit that has obtained the distribution authority will also not occupy the bus for a long time, which improves command distribution. s efficiency. Moreover, the command distribution is realized through hardware, which can effectively reduce the computing resource overhead.

In a possible implementation manner, the preset condition includes: the number of commands is less than the threshold of the number of commands.

In a possible implementation manner, each distribution circuit in the at least one distribution circuit is further configured to monitor in real time the number of commands in the first information buffer when the number of commands is equal to the threshold of the number of commands Whether the number of commands has changed to be less than the threshold of the number of commands; after monitoring that the number of commands has changed to be less than the threshold of the number of commands, the arbitration request signal is sent to the arbitration circuit.

In this way, it can be ensured that the distribution circuit can re-participate in the arbitration of the arbitration circuit when the corresponding arithmetic unit can receive the command, thereby improving the efficiency of command distribution.

In a possible implementation manner, the command number threshold of the corresponding operation unit is based on the size of the data storage space occupied by the currently unprocessed commands in the corresponding operation unit and the total data storage volume of the corresponding operation unit The size of the space is determined.

In this way, even if the number of command line lines of each command is different, the operation unit can be dynamically configured according to the size of the data storage space occupied by the unprocessed commands received by each operation unit and the size of the total data storage space of the operation unit The threshold of the number of commands can reduce the probability of command congestion in a certain computing unit, and at the same time, improve the processing efficiency of the computing unit.

In a possible implementation manner, each distribution circuit in the at least one distribution circuit is further configured to, after receiving the permission permission signal returned by the arbitration circuit based on the arbitration request signal, send a message to the arithmetic unit with the The first operation unit corresponding to the identifier sends the first command.

In a possible implementation manner, each distribution circuit in the at least one distribution circuit, when reading the first command to be sent currently from the command queue corresponding to the distribution circuit, is used to: The corresponding command queue reads the current command line of the first command. The distribution circuit, when reading the number of commands and the threshold of the number of commands from the first information buffer corresponding to the identifier of the operation unit based on the identifier of the operation unit carried in the first command, is used to: When the current command line is the first command line of the first command, based on the operation unit identifier carried in the first command, the first information buffer corresponding to the operation unit identifier is read from the first information buffer. The number of commands and the command number threshold.

In this way, after reading a new command, each distribution circuit can determine whether the number of commands that have been received by the arithmetic unit corresponding to the new command and have not been processed yet reaches the command number threshold.

In a possible implementation manner, each distribution circuit in the at least one distribution circuit is further configured to: in the case that the current command line is a non-first line command line of the first command, to the arbitration A circuit sends the arbitration request signal.

In this way, when the current command line read by the parsing circuit is a non-first line command line of the first command, an arbitration request signal can be directly sent to the arbitration circuit to participate in the arbitration of the arbitration circuit, thereby improving the distribution efficiency.

In a possible implementation manner, each distribution circuit in the at least one distribution circuit is further configured to: determine whether the current command line is the first line of the command line.

In a possible implementation manner, the distribution circuit, when sending an arbitration request signal to the arbitration circuit in response to the number of commands satisfying a preset condition, is configured to: determine the first command line in the first command Whether it is in a ready state; if so, send the arbitration request signal to the arbitration circuit.

In this way, it can be ensured that even when multiple commands in the same command queue are processed by different computing units, each command can be processed sequentially according to the order in which the multiple commands are stored in the command queue, ensuring that the same command queue is stored in the same command queue. The multiple commands are processed sequentially.

In a possible implementation manner, the distribution circuit includes a parsing circuit and a command line buffer; the parsing circuit is respectively connected to the command line buffer and the information buffer. The parsing circuit is used to read the current command line of the first command from the command queue, and determine whether the current command line is the first command line; in the case that the current command line is the first command line Next, based on the operation unit identifier carried in the first line of the command line, read the number of commands and the threshold of the number of commands from the first information buffer corresponding to the identifier of the operation unit; In the case of the above-mentioned threshold of the number of commands, the first line of the command line is sent to the command line buffer. The command line buffer is configured to send the arbitration request signal to the arbitration circuit after receiving the first line of the command line sent by the parsing circuit.

In a possible implementation manner, the parsing circuit is further configured to send the first command line and the first command line to the command line buffer when the number of commands is equal to the command number threshold A pause instruction; the command line buffer is further configured to pause sending the arbitration request signal to the arbitration circuit after receiving the first line of the command line and the first pause instruction sent by the parsing circuit.

In a possible implementation manner, the parsing circuit is further configured to monitor in real time whether the number of commands in the first information buffer changes to be less than the threshold of the number of commands; after monitoring the change in the number of commands After the number of commands is less than the threshold of the number of commands, a first start command is sent to the command line buffer. The command line buffer is further configured to send the arbitration request signal to the arbitration circuit after receiving the first start instruction.

In a possible implementation manner, the distribution circuit further includes a command line counter; the command line counter is connected to the parsing circuit. The parsing circuit, when determining whether the current command line is the first command line, is configured to read the first count value from the command line counter after reading the current command line from the command queue; When the first count value is equal to the first preset value or equal to the original value, it is determined that the current command line is the first command line in the first command. The first preset value is determined based on the number of command line lines of the first command.

In this way, the parsing circuit can determine whether the read current command line is the first command line of the first command by reading the first count value of the command line counter and comparing the first count value with the current count threshold, so as to use A low-cost way to realize the identification of different commands in the same queue.

In a possible implementation, the command counter is connected to the parsing circuit. The parsing circuit is further configured to send the current command line to the first operation unit after monitoring that the command line buffer sends the current command line to the first operation unit when the current command line is the first command line. The command counter sends a second counting instruction; the command counter is used to increase the second counting value by a second value after receiving the second counting instruction.

In this way, the command counter can record the number of commands that have been sent by the corresponding command queue.

In a possible implementation manner, the information buffer is connected to command counters corresponding to the plurality of command queues respectively. The first information buffer is further configured to, after receiving the confirmation information fed back after the first operation unit has processed the first command, based on the command line queue identifier and the confirmation information, send The command counter corresponding to the command queue identifier sends a third counting instruction. The command counter is used to decrease the second count value by a second value after receiving the third count instruction sent by the first information buffer.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. The described embodiments are only some, but not all, embodiments of the present disclosure. The components of the disclosed embodiments generally described and illustrated herein may be arranged and designed in a variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure is not intended to limit the scope of the disclosure as claimed, but is merely representative of selected embodiments of the disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present disclosure.

When the micro-control unit distributes the command, it sends the command to the command distribution unit. After the command distribution unit receives the command, it can use the software program deployed in the command distribution unit to distribute the command to each computing unit. When the command distribution unit sends commands to the operation unit, it will occupy the bus. If too many commands are distributed to an operation unit, the bus resources will always be occupied by the operation unit. In this way, commands may be piled up in the operation unit, but no commands can be executed by other operation units, resulting in lower execution efficiency of the commands, and the computing resources of the operation units cannot be fully utilized.

In another case, if the command received by a certain computing unit has reached its upper limit, but the command distribution unit can still distribute new commands to it according to the distribution strategy, at this time, the new command cannot reach the computing unit because However, the bus resource is occupied all the time, and a new command will not be received until the operation unit executes a command currently received. In this way, congestion occurs when commands are distributed, and thus the efficiency of command distribution is low.

In addition, as the model size of deep learning increases dramatically, and the model structure becomes more complex, the number of commands becomes larger and larger. However, when the command distribution software distributes a large number of commands, a large amount of computing resource overhead is required, and the distribution efficiency is low.

Based on the above research, the present disclosure provides a command distribution device composed of hardware, which distributes commands through a hardware circuit, and each distribution circuit in the command distribution device determines the first operation unit corresponding to the first command to be sent currently. In the case where the number of commands that have been received but not currently processed is less than the command number threshold of the first operation unit, an arbitration request signal is sent to the arbitration circuit, so it can be avoided that the command accumulates in some operation units, and When other computing units have no executable commands, the execution efficiency of the commands is improved, and the computing resource utilization of the computing units is increased.

In addition, each distribution circuit in the command distribution device will send an arbitration request to the arbitration circuit when it is determined that the number of currently unprocessed commands in the first operation unit corresponding to the first command is less than the command number threshold of the first operation unit Signal, that is, when the number of currently unprocessed commands in the first operation unit corresponding to the command to be sent is equal to the command number threshold of the first operation unit, it will not participate in the authority arbitration process, so it will not Occupies the bus; and the distribution circuit that obtains the distribution authority also does not occupy the bus for a long time, which improves the efficiency of command distribution.

In addition, the command distribution apparatus provided by the embodiments of the present disclosure is implemented by hardware, which can effectively reduce computing resource overhead and improve the efficiency of command distribution.

The above are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above-mentioned problems and the solutions to the above-mentioned problems proposed by the present disclosure below should be the results of the inventors' understanding of the present disclosure in the process of the present disclosure. contribution made.

For example, different circuit modules (eg, a distribution circuit, an arbitration circuit) are connected through a line, so that the different circuit modules can transmit level signals (eg, a high level, a low level) through the line. The combination of different level signals can represent different meanings according to the convention. For example, the number 1 represents a high level, and the number 0 represents a low level. Multiple electrical signal transmission lines can be set between the two circuit modules, when different signals are transmitted, different lines are controlled to transmit different level signals, and the combination of different level signals forms different binary numbers. For example, for three lines, the level signals sent in a certain processing cycle are high level, low level, and high level, respectively, and the binary number formed is 101. Different binary numbers represent different meanings by definition.

Specifically, the command number threshold of each operation unit may be set according to the processing capability of each operation unit, which is not limited here.

The commands described in the embodiments of the present disclosure are, for example, a command package, and each command includes multiple command lines.

The command distribution device distributes the command to the corresponding computing unit based on the identifier. In addition, the first line of the command line also includes the number of lines of the command line included in the command. Exemplarily, the first three bits of the first line of the command line represent the identifier of the operation unit to which the command is to be sent, and the fourth and fifth bits represent the number of lines of the command line included in the command. In other command lines except the header line, the specific information of the command is carried, such as the operation to be performed by the command, the address of the operand, and the command status. The specific information of the command may vary according to different commands, which is not limited in this embodiment of the present disclosure.

Referring to FIG. 1, which is a schematic diagram of a command distribution apparatus provided by an embodiment of the present disclosure, the command distribution apparatus includes at least one distribution circuit 10-0 to 10-n (hereinafter collectively referred to as distribution circuit 10) and at least one information cache 20-0 to 20-n (hereinafter collectively referred to as information buffers 20).

Each information buffer 20 in the at least one information buffer is used to store the number of current unprocessed commands in the corresponding arithmetic unit as the number of commands and the command number threshold of the corresponding arithmetic unit;

Each distribution circuit 10 in at least one distribution circuit is used to read the first command currently to be sent from the command queue corresponding to the distribution circuit 10, based on the operation unit identifier carried in the first command, from the operation unit identifier corresponding to The number of commands and the threshold of the number of commands are read from the first information buffer 20 of the first information buffer; in response to the number of commands meeting the preset condition, an arbitration request signal is sent to the arbitration circuit.

Wherein, each distribution circuit 10 is connected with the at least one information buffer 20 .

Referring to FIG. 2 , in another embodiment of the present disclosure, the command distribution apparatus further includes an arbitration circuit 30 , and the arbitration circuit 30 is connected to at least one distribution circuit 10 respectively.

The arbitration circuit 30 is configured to perform authority arbitration on each distribution circuit 10 after receiving an arbitration request signal sent by each distribution circuit 10 in at least one distribution circuit, and return to the distribution circuit 10 that has obtained the transmission authority based on the result of the authority arbitration Permission permission signal.

The command distribution apparatus in the embodiment of the present disclosure is implemented by hardware, which can effectively reduce computing resource overhead. After reading the first command to be sent, each distribution circuit of the command distribution device reads the number of commands and the number of commands from the first information buffer corresponding to the identifier of the operation unit based on the identifier of the operation unit carried in the first command. Threshold; when the number of commands is less than the threshold of the number of commands, an arbitration request signal is sent to the arbitration circuit. Therefore, it is possible to avoid a situation in which command accumulation occurs in some computing units, while other computing units have no executable commands, thereby improving the execution efficiency of commands and increasing the computing resource utilization rate of the computing units.

And the distribution circuit will not participate in the authority arbitration process and will not occupy the bus when the number of currently unprocessed commands in the first operation unit corresponding to the first command is equal to the command number threshold of the first operation unit; and The distribution circuit that obtains the distribution authority also does not occupy the bus for a long time, thereby improving the efficiency of command distribution.

The command distribution apparatus described in the embodiments of the present disclosure will be introduced in detail below.

For the distribution circuit 10, when the first command to be sent currently is read from the command queue corresponding to the distribution circuit, for example, the current command line of the first command is read from the command queue corresponding to the distribution circuit.

For each information buffer 20 in the at least one information buffer, it is also used to obtain a dynamically configured command number threshold of the corresponding operation unit. The command number threshold corresponding to the operation unit is determined based on, for example, the size of the data storage space occupied by the currently unprocessed commands in the corresponding operation unit and the total data storage space size of the corresponding operation unit.

Here, the dynamic configuration is, for example, configuration by any one of the host, the distribution circuit 10 , and the configuration unit connected to each information buffer 20 .

Exemplarily, the host or the configuration unit connected to each information buffer 20 determines the corresponding operation unit based on the size of the data storage space occupied by the currently unprocessed command in the corresponding operation unit and the size of the total data storage space of the corresponding operation unit. command count threshold. For example, the total data storage space of the operation unit can store 50 lines of command lines, the number of unprocessed commands received by the operation unit is 3, and the data storage space occupied by the three commands is 30 lines , the operation unit still has 20 lines of storage space. Assuming that the maximum number of command lines of a command is 15 lines, the host or the configuration unit connected to each information buffer 20 determines that the operation unit has a command number threshold of 4.

Or, exemplarily, after the distribution circuit 10 reads the first command line of the first command from the command queue corresponding to the distribution circuit 10, parses the first command line to obtain the number of command lines of the first command, and sends the first information to the first information The buffer sends the number of command lines; after receiving the number of command lines sent by the distribution circuit 10, the first information buffer is based on the number of command lines, the size of the data storage space occupied by the currently unprocessed commands in the first arithmetic unit, And the size of the total data storage space of the first operation unit determines the command number threshold of the first operation unit. For example, the total data storage space of the first operation unit can store 40 lines of command lines, the number of unprocessed commands received by the first operation unit is 3, and the data storage space occupied by the three commands The size is 30 lines, and the first operation unit has 10 lines of storage space left. If the number of command lines of the first command is greater than 10 lines, the threshold of the number of commands of the first operation unit is 3; if the command line of the first command If the number of lines is less than or equal to 10 lines, the command number threshold of the first operation unit is 4.

For each distribution circuit 10 in at least one distribution circuit, read the current command line of the first command from the command queue corresponding to the distribution circuit 10, and determine whether the current command line is the first command line of the first command.

Case A1: In the case where it is determined that the current command line is the first command line of the first command, the distribution circuit 10, based on the operation unit identifier carried in the first line of the command line, selects from the first information buffer corresponding to the operation unit identifier. The number of currently unprocessed commands in the first operation unit corresponding to the first command is read as the number of commands and the command number threshold of the first operation unit, and an arbitration request signal is sent to the arbitration circuit in response to the number of commands meeting a preset condition. The preset condition includes, for example, that the number of commands is less than a threshold of the number of commands. Therefore, when the number of commands is smaller than the command number threshold, the distribution circuit 10 sends an arbitration request signal to the arbitration circuit 30 .

Wherein, the first operation unit is the operation unit corresponding to the first command to be sent currently, and the first information buffer is the information buffer corresponding to the first operation unit; the operation unit identifier includes, for example, the identifier of the corresponding operation unit (for example, At least one of the contents of the address of the corresponding operation unit), the identifier of the corresponding information buffer (for example, the address of the corresponding information buffer) and the like. In addition, the distribution circuit 10 may also record the operation unit identifier; when the current command line is a non-first line command line, use the recorded operation unit identifier to send the current command line to the first operation unit corresponding to the operation unit identifier.

The current command line read by the distribution circuit 10 is the first command line, which means that the distribution circuit wants to start sending a new first command, and needs to determine the received, but not yet stored, first operation unit corresponding to the new first command. Whether the number of processed commands (hereinafter referred to as the number of commands) has reached the maximum value; if the number of commands is less than the threshold of the number of commands, it means that the number of received but unprocessed commands stored by the first operation unit has not reached the maximum value. , the first arithmetic unit can also normally receive the command sent by the distribution circuit. At this time, the distribution circuit can send an arbitration request signal to the arbitration circuit 30 to participate in the arbitration of the arbitration circuit 30 to obtain the opportunity to send the command to the first arithmetic unit.

In addition, when the number of commands is equal to the threshold of the number of commands, the distribution circuit 10 monitors in real time whether the number of commands in the first information buffer changes to be less than the threshold of the number of commands; after monitoring that the number of commands changes to be less than the threshold of the number of commands, An arbitration request signal is sent to the arbitration circuit 30 .

When the number of received but unprocessed commands stored in the first arithmetic unit reaches the maximum value, the command sent by the distribution circuit 10 cannot be received until at least one of the stored commands is processed. The command sent by the distribution circuit 10 is received.

After the first arithmetic unit processes a command, it will give feedback information to the first information buffer, and the first information buffer will update the number of commands after receiving the feedback information, for example, reduce the number of commands by 1, and the distribution circuit 10 After monitoring that the number of commands stored in the first information buffer changes to be less than the command number threshold, an arbitration request signal is sent to the arbitration circuit 30 to participate in the arbitration of the arbitration circuit 30 to obtain an opportunity to send commands to the first arithmetic unit.

Case A2: When it is determined that the current command line is a non-first line command line of the first command, the distribution circuit 10 directly sends an arbitration request signal to the arbitration circuit 30 .

In the case where the current command line is not the first command line of the first command, it means that the distribution circuit 10 has determined that the first operation unit corresponding to the first command has received the received command line when sending the first command line of the first command. However, the number of unprocessed commands has not reached the maximum value. Therefore, when the current command line read is not the first command line of the first command, the distribution circuit 10 can directly send an arbitration request signal to the arbitration circuit 30. , without the need to determine whether the current number of unprocessed commands in the first operation unit is less than the command number threshold.

Moreover, for a certain command, only after all the command lines of the command are sent to the corresponding operation unit, the corresponding operation unit will process the processing task corresponding to the command based on the command. Therefore, if the current command line is a non-first-line command line, you can continue to send the non-first-line command line to the corresponding operation unit. Therefore, the distribution circuit 10 directly sends an arbitration request signal to the arbitration circuit 30 when the current command line is a non-first-line command line.

When the distribution circuit 10 sends the arbitration request signal to the arbitration circuit, for example, any one of the following modes B1 or B2 may be adopted:

Mode B1: When the number of commands is less than the command number threshold, the distribution circuit 10 sends an arbitration request signal to the arbitration circuit 30 .

Mode B2: when the number of commands is less than the threshold of the number of commands, the distribution circuit 10 determines whether the first line of the command line is in a ready state; if so, it sends an arbitration request signal to the arbitration circuit 30; if it is not in a ready state, it does not send the arbitration circuit 30. The arbitration request signal is sent until it changes to the ready state.

Here, the current command line is in the ready state, which means that when the number of commands is less than the command number threshold, the current command line can be sent to the corresponding first operation unit. The ready state includes, for example, any one of the following states (1) to (2):

State (1): The first operation unit corresponding to the first command where the first line of the command line is located is the same as the second operation unit corresponding to the second command recently sent by the command queue.

State (2): The first operation unit corresponding to the first command where the first command line is located is different from the second operation unit corresponding to the second command recently sent by the command queue, but the second command is processed by the second operation unit complete.

Here, for different commands belonging to the same command queue, they have a sequential processing order; in many cases, the processing of the next command can only be processed after the previous command has been processed; therefore, in order to ensure that they belong to the same command queue The processing sequence between different commands in the command queue. If different commands are sent to different operation units, the operation unit corresponding to the previous command needs to process the previous command, and then send the next command to the next command. The corresponding operation unit is sent.

If different commands are sent to the same operation unit, since the operation unit will only process another command after processing one command, if the previous command has not been processed, each command in the latter command can be processed. The rows are sent to the same operation unit, so that the processing order between different commands in the same command queue can also be guaranteed.

Therefore, in the above state (1), when the first operation unit is the same as the second operation unit, the current command line is determined as the ready state; in the above (2), in the first operation unit and the second operation unit When the units are different, and the second command is processed by the second operation unit, the current command line is determined to be in a ready state.

In addition, each distribution circuit 10 in the at least one distribution circuit sends a first command to the first operation unit corresponding to the operation unit identifier after receiving the authorization permission signal returned by the arbitration circuit 30 based on the arbitration request signal.

The command distribution device may further include a command distribution interface 40; the distribution circuit 10 may be connected to the command distribution interface 40, and when sending the current command line to the first operation unit, the current command line and the operation unit identifier may be sent together To the command distribution interface 40 . Correspondingly, the command distribution interface 40 is connected to the bus, and based on the identification of the operation unit, sends the current command line to the first operation unit connected to the bus through the bus.

In addition, the command distribution interface 40 can also be connected to the arbitration circuit 30; the distribution circuit 10 sends the current command line and the operation unit identifier to the arbitration circuit 30 after receiving the permission permission signal; the arbitration circuit 30 sends the current command line and the operation unit identifier to the arbitration circuit 30; The identifier is sent to the command distribution interface 40 together, and then the command distribution interface 40 sends the current command line to the first operation unit connected to the bus through the bus based on the operation unit identifier.

The command distribution interface 40 may be connected, for example, to a bus interface of a bus. The command distribution interface 40 sends the current command line and the operation unit identifier to the bus interface, and the bus interface sends the current command line to the first operation unit through the bus and the operation unit identifier.

3 is a schematic structural diagram of a distribution circuit 10 provided by the disclosed embodiment. In this embodiment, the distribution circuit 10 includes a parsing circuit 101 and a command line buffer 102; the parsing circuit 101 and the command line buffer 102 and the at least one information buffer 20 is connected;

The parsing circuit 101 is used to read the current command line of the first command from the command queue, and determine whether the current command line is the first command line; in the case that the current command line is the first command line, based on the first command line carried The arithmetic unit identifier, reads the command quantity and the command number threshold from the first information buffer corresponding to the arithmetic unit identifier; In the case that the command quantity is less than the command number threshold, send the first line command line to the command line buffer 102;

The command line buffer 102 is configured to send an arbitration request signal to the arbitration circuit after receiving the first line of the command line sent by the parsing circuit 101 .

For example, in FIG. 3 , parsing circuit 0 is connected to command line buffer 0 , and parsing circuit 1 is connected to command line buffer 1 .

The process of reading the command queue by the parsing circuit 101 includes, for example: the parsing circuit 101 monitors the level state between it and the command queue, and monitors the level state between it and the command line buffer 102; The level state of the command line indicates that there is a command to be sent in the command queue, and the level state between the command line buffer 102 and the command line buffer 102 indicates that the command line buffer 102 is empty, then the current command line is read from the command queue.

In addition, the process of reading the command queue by the parsing circuit 101 may further include: when the command queue stores the command to be sent, sending a first level signal to the parsing circuit 101, where the first level signal represents that the command to be sent is stored in the command queue ; After receiving the first level signal, the parsing circuit 101 sends a second level signal to the command line buffer 102. After the command line buffer 102 receives the second level signal, there is no signal in the command line buffer 102. In the case of storing any command line, a third level signal is sent to the parsing circuit 101. After receiving the third level signal, the parsing circuit 101 feeds back the fourth level signal to the command queue, and the command queue receives the fourth level signal. After the signal is sent, the parsing circuit 101 sends the current command line among the plurality of command lines to be sent.

When the command line buffer 102 stores a command line, it feeds back a fifth level signal to the parsing circuit 101. After receiving the fifth level signal, the parsing circuit 101 feeds back a sixth level signal to the command queue, and the command queue After receiving the sixth level signal, continue to send the first level signal to the analysis circuit 101 until the fourth level signal fed back by the analysis circuit 101 is received.

It should be noted that the above-mentioned sending of the first level signal, the second level signal, the third level signal, the fourth level signal, the fifth level signal, and the sixth level signal may be a transmission state, or may It is the corresponding circuit module that maintains the state corresponding to the level signal. For example, if the first level signal sent by the command queue to the parsing circuit 101 is a high level, then the command queue may send a high level to the parsing circuit 101 once every clock cycle, or the command queue may keep a high level all the time. state.

In addition, the parsing circuit 101 is further configured to send the first line of the command line and the first pause instruction to the command line buffer when the number of commands is equal to the threshold of the number of commands; the command line buffer 102, after receiving the After the first line of the command line and the first pause instruction, the arbitration request signal is sent to the arbitration circuit by pause. The parsing circuit 101 monitors in real time whether the number of commands in the first information buffer has changed to be less than the threshold of the number of commands; after monitoring that the number of commands has changed to be less than the threshold of the number of commands, the parsing circuit 101 sends the first start to the command line buffer 102 command; after receiving the first start command, the command line buffer 102 sends an arbitration request signal to the arbitration circuit 30 .

After the distribution circuit 10 reads the current command line, it determines whether the current command line is the first command line of the first command. The arithmetic unit identifier, reads the number of commands and the threshold of the number of commands from the first information buffer corresponding to the identifier of the arithmetic unit; in the case that the number of commands is less than the threshold of the number of commands, determine whether the first line of the command line is in a ready state; The arbitration circuit 30 transmits an arbitration request signal.

For the ready state corresponding to the current command line, reference may be made to any one of the above states (1) to (2), which will not be repeated here.

In another embodiment of the present disclosure, the distribution circuit 10 further includes a command line counter 103 ; the command line counter 103 is connected to the parsing circuit 101 .

The parsing circuit 101 is configured to read the first count value from the command line counter 103 after reading the current command line from the command queue; when the first count value is less than the first preset value and greater than the original value, determine The current command line is the non-first command line in the first command.

The first preset value is determined based on the number of command line lines of the first command.

And the first preset value is related to the original value of the command line buffer 102 . Specifically, for the same command, for example, when the original value is m and the number of command lines of the command is n, the first preset value can be m+n; the original value can be set according to the actual situation, such as the original value It can be set to 0, or 1, etc., and can be set according to actual needs.

Wherein, the first value is set according to the specific application situation, for example, for the number of lines of the command line read by the recording parsing circuit 101 , the first value is, for example, 1.

In another embodiment of the present disclosure, when the first count value read by the parsing circuit 101 is equal to the first preset value, or equal to the original value, the parsing circuit 101 determines that the current command line is the first command line in the first command, Update the first preset value based on the number of command line lines of the first command and send a reset instruction to the command line counter 103, as shown in ⑥ in FIG. 3 ; after the command line counter 103 receives the reset instruction sent by the parsing circuit 101 , reset the first count value to the original value and then increase the first value.

In the case that the parsing circuit 101 determines that the current command line is the first line command of the first command, based on the operation unit identifier carried in the first line command line, the number of commands and the number of commands are read from the first information buffer corresponding to the operation unit identifier. Threshold; if the number of commands is less than the threshold of the number of commands, determine whether the first line of the command line is in a ready state; if so, send an arbitration request signal to the arbitration circuit 30 .

Referring to FIG. 3 , in another embodiment of the present disclosure, the distribution circuit 10 further includes a judgment circuit 104 .

The analysis circuit 101 is connected to the judgment circuit 104 .

The judgment circuit 104 is used to receive the arithmetic unit identifier sent by the parsing circuit 101, and based on the arithmetic unit identifier, it is judged that the first arithmetic unit corresponding to the first command and the second arithmetic unit corresponding to the second command that the command queue has recently sent are different, And when the second command is not processed by the second arithmetic unit, send a second pause command to the command line buffer 102;

The command line buffer 102 is further configured to suspend sending an arbitration request signal to the arbitration circuit 30 when the second suspend instruction sent by the judgment circuit 104 is received.

In another embodiment, the command counter 105 is further included in the distribution circuit 10 . The command counter 105 is connected to the judgment circuit 104 .

The judgment circuit 104 is further configured to read the second count value from the command counter 105 after receiving the operation unit identifier sent by the analysis circuit 101, and determine the first count value when the second count value is greater than the second preset value. The second command has not been processed by the second operation unit;

Among them, the command counter 105 is used to count the commands corresponding to the command queue that are currently sent but not yet processed.

After the judgment circuit 104 receives the operation unit identifier sent by the parsing circuit 101, it is determined that the received operation unit identifier is consistent with the second identifier of the second operation unit corresponding to the second command that the command queue has recently sent. That is, the ready state described in the above state (1), the judgment circuit 104 maintains a fixed level signal such as a high level. When the judgment circuit 104 is maintained at a high level, the command line buffer 102 receives the parsing circuit 101. After sending the current command line and the operation unit identifier, the arbitration request signal is sent to the arbitration circuit 30 as shown in ⑨ in FIG. 3 . The second identifier may be, for example, a binary array, which is used to represent the address of the second operation unit.

When the judging circuit 104 is kept at a high level, the command line buffer 102, after receiving the current command line and the arithmetic unit identifier sent by the parsing circuit 101, sends the The arbitration circuit 30 sends the arbitration request signal as shown in ⑨ in FIG. 3 .

In another embodiment of the present disclosure, the judgment circuit 104 reads the second count value from the command counter 105 after receiving the operation unit identifier sent by the parsing circuit 101 , and when the second count value is greater than the second preset value In this case, it is determined that the second command that has been sent recently has not been processed by the second operation unit, and when the identifier of the operation unit is inconsistent with the second identifier of the second operation unit, the judgment circuit 104 sends the command to the command line buffer 102. The second pause command is shown in Figure 3

As shown, the command line buffer 102 suspends sending the arbitration request signal to the arbitration circuit 30 when receiving the second suspend instruction sent by the judgment circuit 104 .

The judgment circuit 104 monitors whether the second count value in the command counter 105 changes to the second preset value when it is determined that the second command has not been processed by the second arithmetic unit; and monitors the second count of the command counter 105 When the value changes to the second preset value, a second start command is sent to the command line buffer 102 as shown in FIG. 3

As shown; the command line buffer 102 sends an arbitration request signal to the arbitration circuit 30 after receiving the second start command.

After receiving the arbitration request signal sent by each command line buffer 102, the arbitration circuit 30 performs authority arbitration on each command line buffer 102, and based on the result of the authority arbitration, returns the authority permission to the command line buffer 102 that has obtained the sending authority The signal is shown in Figure 3

shown.

After receiving the permission permission signal returned by the arbitration circuit 30 based on the arbitration request signal, the command line buffer 102 sends the current command line to the first operation unit corresponding to the first command.

In a possible implementation manner, the command line buffer 102 sends the current command line and the arithmetic unit identifier of the first arithmetic unit to the arbitration circuit 30 after receiving the permission permission signal returned by the arbitration circuit 30 based on the arbitration request signal. 3 in

After receiving the current command line and the arithmetic unit identification, the arbitration circuit 30 sends the current command line and the arithmetic unit identification to the command distribution interface 40 as shown in Figure 3

shown; the command distribution interface 40 sends the current command line and the operation unit identification to the bus interface after receiving the current command line and the arithmetic unit identification as shown in Figure 3

After receiving the current command line and the operation unit identifier, the bus interface sends the current command line to the first operation unit based on the operation unit identifier.

Wherein, the bus is connected to each operation unit, and the bus selects the operation unit to be communicated through the identification of each operation unit.

In another possible implementation, the command line buffer 102 is connected to the command distribution interface 40; after receiving the permission permission signal returned by the arbitration circuit 30 based on the arbitration request signal, the command line buffer 102 sends the command distribution interface 40 The current command line and the operation unit identifier; the command distribution interface 40 sends the current command line and the operation unit identifier to the bus interface after receiving the current command line and the operation unit identifier; the bus interface receives the current command line and the operation unit identifier. After the unit identification, the current command line is sent to the first operation unit based on the operation unit identification.

In addition, the command line buffer 102 is connected to the information buffer 20; the parsing circuit 101 sends the command queue identifier of the command queue to the command line buffer 102 when it is determined that the current command line is the first command line in the first command; the command When the line buffer 102 sends the current command line to the first operation unit corresponding to the first command, it sends the command queue identifier to the first information buffer; wherein, the first information buffer is the information buffer corresponding to the first operation unit device 20.

shown.

The first information buffer receives the command queue identifier; and the confirmation information fed back after receiving the first operation unit to process the first command is as shown in Figure 3

After shown, based on the command queue identifier and the confirmation information, a third counting instruction is sent to the command counter 105 as shown in FIG. 3

As shown, the first information buffer updates the number of commands, for example, decrements the number of commands by 1, after receiving the confirmation information fed back after the first operation unit has processed the first command.

After receiving the third counting instruction sent by the first information buffer, the command counter 105 reduces the second counting value by the second value.

After the operation unit completes processing the command, the acknowledgement information fed back to the information buffer 20 may be, for example, an acknowledgement character (Acknowledge character, ACK).

In this way, the command counter 105 can count the commands corresponding to the command queue that are currently sent but not yet processed.

It should be noted that in Figure 3

It does not represent a specific processing sequence, but only to illustrate the processing logic in two cases where the current command line acquired by the distribution circuit 10 is the first command line or the non-first command line of the first command to be sent currently.

In addition, after each arbitration, the arbitration circuit 30 only returns a permission permission signal to one command line register 102 , that is, the right to use the bus can only be given to one command line register 102 at the same time. The arbitration logic of the arbitration circuit 30 may be defined based on the registers connected to the arbitration circuit 30, for example, arbitration is performed by dividing the command queues into levels, or arbitration is based on a polling manner, which is not limited here.

Those skilled in the art can understand that, in the above device of the specific embodiment, the writing order of each step does not mean a strict execution order but constitutes any limitation on the implementation process, and the specific execution order of each step should be based on its functions and possible Internal logic is determined.
