Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, data transmission between modules through a bus is high in reliability, but the bus needs to be occupied, when the bus is busy, data transmission needs to wait, timeliness is low, and when a large amount of data needs to be transmitted between two modules, bus time is always occupied, so that the bus is busy for a long time, and other modules cannot be used. The method is simple through data transmission between the modules in an FIFO mode, the two modules are connected only through the FIFO mode, and other information interaction is avoided. In order to overcome the technical problem, the application provides a method for transmitting data between modules in a chip, which can initiate data transmission at any time without occupying a bus, and improves the efficiency of data transmission between modules in the chip.
The embodiment of the application discloses a method for transmitting data between modules in a chip, which is applied to a first target module in the chip, and as shown in fig. 1, the method can include the following steps:
step S11: and receiving a data transmission request sent by the second target module in the chip through the self request interface.
In this embodiment, a first target module in the chip is a data sending end, which may also be referred to as a requested end, and the first target module obtains, through a request interface configured in advance, a data transmission request sent by a second target module in the chip through its own request interface, where the second target module is a data receiving end, which may also be referred to as a requested end. That is to say, each of the modules in the chip is configured with a respective request interface, and the request interface is used for sending a data transmission request to another module or receiving a data transmission request sent by another module.
Step S12: and sending a request response to a response interface of the second target module through a response interface of the second target module according to the data transmission request so as to establish communication connection between the first target module and the second target module.
In this embodiment, after receiving the data transmission request, the first target module sends a request response to a response interface of the second target module through its own response interface, where the request response is used to characterize and accept the data transmission request of the second target module, so as to establish a communication connection between the first target module and the second target module. That is, each of the on-chip modules is configured with a respective reply interface for sending a reply response to the other module.
In this embodiment, the sending a request response to the response interface of the second target module through the response interface thereof to establish a communication connection between the first target module and the second target module may include: sending a request response to a response interface of the second target module through a response interface of the second target module; and receiving a data response corresponding to the request response, fed back by the second target module, through the response interface of the second target module to establish communication connection between the first target module and the second target module.
It can be understood that, in the process of establishing a communication connection between a first target module and a second target module, in the first step, the second target module sends a data transmission request to the first target module through a request interface of the second target module; secondly, after receiving the data transmission request, the first target module sends a request response to the second target module through a response interface of the first target module; and thirdly, after receiving the request response, the second target module sends a data response interface to the first target module through a response interface of the second target module so as to represent that the data is ready to be received, and the first target module can start to transmit the data to the second target module until the communication connection between the first target module and the second target module is successfully established.
Step S13: and sending target data corresponding to the data transmission request to a data transmission interface of the second target module through a data transmission interface of the second target module according to the communication connection.
In this embodiment, after the communication connection is successfully established, the first target module transmits the data and the target data corresponding to the data transmission request to the second target module through the data transmission interface of the first target module and the data transmission interface of the second target module. That is, each of the modules in the chip is configured with its own data transmission interface, and the response interface is used for data transmission with other modules.
In this embodiment, the sending, by the data transmission interface of the second target module, the target data corresponding to the data transmission request to the data transmission interface of the second target module may include: acquiring a data volume acquisition request sent by the second target module through a response interface of the second target module; the data volume acquisition request is a request generated by the second target module according to the data processing state of the second target module; determining the size of target data according to the data volume acquisition request, and determining corresponding target data according to the data transmission request; and generating a data packet to be sent according to the size of the target data based on the target data, and sending the data packet to be sent to a data transmission interface of the second target module through a data transmission interface of the data packet to be sent. It can be understood that, in this embodiment, the feedback variable window mechanism is implemented by responding to the data amount obtaining request sent by the interface, where the size of the window is several data transmissions at a time, and the feedback variable window is a variable size that can change several data transmissions at a time. Therefore, the size of single data transmission can be flexibly adjusted, in the prior art, the fixed window is set to be too small, if a sending end sends a datum, a receiving end confirms to receive the datum, the cost is too large, and the transmission rate can be reduced; if the window is set to be too large, for example, 100 data are transmitted each time, and the receiving end can only receive and process 50 data, which may cause data loss and congestion, therefore, the feedback variable window is adopted in the embodiment to effectively solve the problem.
In this embodiment, before receiving, through the request interface of the second target module, a data transmission request sent by the second target module through the request interface of the second target module, the method may further include: configuring respective input and output type interfaces for the target modules in the chip according to preset interface configuration information so that the first target module and the second target module both comprise the request interface, the response interface and the data transmission interface; the interface configuration information includes an interface format and an interface number. Namely, each module in the chip is configured with a respective request interface, a response interface and a data transmission interface, and the types of the three interfaces are input and output type interfaces, namely, half-duplex communication can be supported. In addition, the first target module and the second target module in this embodiment are only generic, and any one module in the chip can be used as a request end and a requested end.
In this embodiment, configuring respective input/output type interfaces for the target modules in the chip according to the preset interface configuration information may include: configuring a request interface for a target module in the chip according to the request interface configuration parameters in the preset interface configuration information to obtain the request interface; configuring an ACK response interface for a target module in the chip according to a response interface configuration parameter in the preset interface configuration information to obtain the response interface; the response interface configuration parameters comprise a request format corresponding to the request response, a request format corresponding to the data response, and a request format corresponding to the data volume acquisition request; and configuring a data interface for the target module in the chip according to the data interface configuration parameters in the preset interface configuration information to obtain the data transmission interface.
It can be understood that, for example, fig. 2 is a schematic diagram of a specific structure of an inter-module DATA transmission interface in a chip, where a request interface configured for each module may specifically be a request interface (REQ interface), and a response interface may specifically be an ack (acknowledgement) response interface and a DATA transmission interface (DATA interface). The REQ interface is configured to transmit a data transmission request signal, bit width is 1bit, a high level is defined as REQ valid, data transmission is requested, a low level is REQ invalid, no data transmission request exists, and the REQ needs to be kept in a high level valid state all the time in the data transmission process. The data transmission interface is used for transmitting data. Bit width is 1bit, and the serial transmission is carried out.
The ACK interface is used for responding to data transmission, the ACK is divided into a request response and a data response, and the specific interface format configuration may be:
ACK [0] represents a request response, the bit width is 1bit, the first target module sends the request response to the second target module, namely the requested module sends the request to the request module, and is used for responding the data transmission request, the high level indicates that the response is successful, otherwise, the request module does not receive the REQ request signal or the requested module cannot transmit the data;
ACK [1] represents data response, bit width is 1bit, the second target module sends the response to the first target module, namely the request module sends the response to the requested module, which is used for responding ACK [0], indicating that the requested end can start sending data, high level indicates response success, otherwise, the request module is no response, namely the request module does not receive response signal of ACK [0] or the request module does not prepare for receiving data;
and the ACK [ N:2] represents a data volume acquisition request, has configurable bit width and is used for feeding back a variable window to control data transmission.
It can be seen that ACK [0] and ACK [0] are request responses for connection establishment between two modules, and ACK [ N:2] is a feedback variable window response signal (N is a set bit width value) for feedback variable window setting control data transmission. Therefore, the speed of data transmission can be controlled by feeding back the setting of the variable window, data transmission is initiated by adopting a mode based on the REQ request, connection is established and data transmission is adjusted through the ACK response signal, and resource waste and transmission blockage are avoided.
In this embodiment, before acquiring the data volume acquisition request sent by the second target module through its own response interface, the method may further include: determining the size of primary data transmission according to the data transmission configuration information; and sending target data corresponding to the data transmission request to a data transmission interface of the second target module through a data transmission interface of the second target module according to the size of the first data transmission. In this embodiment, after acquiring the data volume acquisition request sent by the second target module through its own response interface, the method may further include: judging whether the size of the target data in the data volume acquisition request is zero or not; and if the size of the target data is zero, stopping sending the target data to the second target module.
For example, as shown in fig. 3, the workflow of the feedback variable window is as follows: when data is sent for the first time, the default window size is adopted, namely the default first data transmission size can be set to be 8 bits, at the moment, after the second target module receives the data, the data is responded through ACK [ N:2] and returned to the first target module, the content of the response signal is the number of the data which is expected to be transmitted for the next time, namely after the first 8-bit data is transmitted, if the second target module has the capacity to process more data, the response signals with the N of 16, 24 or 32 and the like are sent through the ACK [ N:2], and the first target module is told that the data with the number of bits can be sent for the next time; if the second target module is not capable of handling so much data or does not already need to transmit data at this point, the first target module is told to reduce data transmission by sending an acknowledgement signal of 4, 2, etc. via ACK N: 2. If ACK [ N:2] sends a response signal with N being 0, the first target module stops sending data after receiving the signal. If the first target module does not receive the ACK signal, the second target module fails to receive the ACK signal, and the first target module retransmits the ACK signal. By setting the feedback variable window, half-duplex data transmission is realized, the data transmission speed can be controlled, resource waste and transmission blockage are avoided, and the data transmission efficiency is improved.
FIG. 3 shows a specific timing diagram for inter-module data transmission within a chip:
(1) assuming that two modules need to perform data transmission, a first target module (a requested module, i.e. a data sending module, i.e. a sending end) and a second target module (a requested data transmission module, i.e. a data receiving module, i.e. a receiving end);
(2) when the receiving end needs the sending end to send data, the receiving end sends a REQ signal to the sending end;
(3) the sending end receives the REQ signal and sends an ACK [0] response signal to the receiving end according to the self condition;
(4) after receiving ACK [0], the receiving end sends ACK [1] response signal to the sending end according to self condition;
(5) after receiving ACK [1], the sending end starts to send data, and the first time sends 8-bit data;
(6) after receiving the data, the receiving end sends ACK [ N:2] to the sending module according to the self condition (if the receiving end needs a large amount of data transmission and has the capacity to process at the moment, a larger value of ACK [ N:2] can be sent to the sending module, if the receiving end does not have the capacity to process more data at the moment or does not need the data transmission, the value of ACK [ N:2] can be smaller or 0);
(7) after receiving ACK [ N:2], the sending end sets the number of data to be sent next time according to the value;
(8) and (5) repeating the steps (6) and (7) until ACK [ N:2] is 0, namely no data transmission is needed.
As can be seen from the above, in this embodiment, a first target module in a chip receives, through a request interface of the first target module, a data transmission request sent by a second target module in the chip through a request interface of the second target module; according to the data transmission request, sending a request response to a response interface of the second target module through a response interface of the second target module so as to establish communication connection between the first target module and the second target module; and sending target data corresponding to the data transmission request to a data transmission interface of the second target module through a data transmission interface of the second target module according to the communication connection. It can be seen from above that, the module is equipped with request interface, answer interface and data transmission interface in this embodiment in the chip, send or receive the data transmission request through self request interface between the different modules in the chip, simultaneously, send the answer response through self answer interface between the different modules in the chip to and carry out data transmission through self data transmission interface between the different modules in the chip, can need not to occupy the bus and initiate data transmission at any time, improved the data transmission efficiency between the modules in the chip.
