Background technique

With the development of complex semiconductor technology, the research and development of integrated circuits have gradually deepened, and the demand for very large-scale integrated circuits has also increased.

The number of transistors contained in VLSI circuits is very large. As a result, the power consumption of VLSI circuits will become larger and larger. Among them, the VLSI caused by excessive transient current (DI/DT) The overload operation of many loads in integrated circuits causes problems such as heat generation, etc., and excessive transient current will also cause an instant drop in the supply voltage. An excessively low supply voltage will cause functional errors in very large scale integrated circuits, leading to There will be serious consequences.

For this reason, in the design of general-purpose graphics processing units (GPGPU), the method of reducing the input frequency is usually used to reduce the transient current; or when designing the overall VLSI circuit, hardware devices are added to control the transient current to stabilize the overall load. normal work.

However, using the frequency reduction method will not only affect the performance of VLSI, but also increase the frequency control requirements; and adding hardware equipment will not only affect the stability of the circuit current due to the increase in devices, but also increase the packaging and testing requirements. Difficulty.

Therefore, how to control the transient current while ensuring the performance of the integrated circuit has become an urgent technical problem that needs to be solved.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

Figure 1 exemplarily shows a schematic diagram of the internal basic architecture of a GPGPU. As shown in Figure 1, the basic architecture may include: a resource allocation module 01 and a data processing unit 02.

In very large-scale integrated circuits, especially in general-purpose graphics processing units (GPGPU), the data processing unit (DU) 02 is the basic module that builds the entire GPGPU and is the smallest independent functional unit.

The resource allocation module 01 is responsible for allocating computing tasks to the data processing unit 02. The data processing unit 02 completes the process of executing computing tasks such as fetching, decoding, executing and writing back according to the computing tasks assigned by the resource allocation module 01 .

Among them, the computing tasks allocated by the resource allocation module 01 come from the computing task requests issued by the processing program. When the processing program finds that the integrated circuit needs to perform computing tasks, it sends the computing task request to the resource allocation module 01. The resource allocation module 01 receives the Upon receipt of the computing task request, the computing task is assigned to the data processing unit 02.

When the data processing unit 02 receives the computing task, it gradually starts to execute the computing task within a certain time (window period).

It is easy to understand that during the window period, when the data processing unit 02 is started, a large transient current will be generated, and the loss caused by the transient current will account for the vast majority of the power consumption of the GPGPU. When multiple data When the processing units 02 perform processing tasks at the same time, there will be two or more data processing units 02 starting at the same time within a window period, that is, the window periods of different data processing units 02 may overlap, and the window periods of each data processing unit 02 may overlap. Overlapping window periods will cause the transient current to further increase, which will not only have a great impact on the power consumption of the GPGPU, but also cause functional errors in the VLSI circuit, thereby affecting the performance of the GPGPU chip.

The window period represents the time interval between the initial startup time of a data processing unit 02 and the stable operation time. A data processing unit 02 is triggered to start by a computing task within a window period and gradually runs until stable.

Specifically, please refer to FIG. 2 , which is a schematic diagram illustrating the relationship between the time when the data processing unit of the GPGPU loads a task and time.

In order to facilitate the explanation of the specific conditions of each data processing unit DU when loading tasks, only the working conditions of some data processing units DU are shown in Figure 2.

As shown in the figure, DU0 receives the computing task assigned by the resource allocation module 02 at time 5, and is triggered to start according to the computing task DU0. During the window period, DU0 begins to run gradually until time 9 is fully loaded, and then Stable operation. After the time interval T after DU0 is triggered to start, DU1 is assigned to the computing task at time 6 and starts running until it reaches full load and stable operation at time 10. Similarly, DU2 and DU3 will gradually run within their respective window periods after receiving the assigned computing tasks until they reach full load computing and operate stably.

It can be seen that within the time interval of a window period, that is, the time period from the trigger time 5 of DU0 to the stable time 9 of DU0 in Figure 2, four data processing units 02 are running at the same time, including: DU0, DU1, and DU2 and DU3, so that within the time interval of a window period, the transient current generated when four data processing units 02 are running at the same time will be included, and due to the time intervals between different data processing units 02, all data The proportion of the total time required by the processing unit 02 to execute the computing task is very small. Therefore, the execution of the computing tasks by multiple data processing units 02 can be regarded as being executed simultaneously. Then the transient state generated by the multiple data processing units 02 The accumulation of current can also be regarded as the transient current generated at the same time, which will cause a sharp increase in the transient current at a certain moment.

Specifically, please refer to FIG. 3 , which exemplarily shows a schematic diagram of basic transient current changes when the data processing unit loads a task.

As shown in the figure, when the integrated circuit needs to perform task calculations, the resource allocation module 01 allocates the calculation tasks, and multiple data processing units 02 are triggered by the calculation tasks. At time 1340, a huge transient current change will occur. The transient current is the accumulation of transient currents loading tasks when multiple data processing units 02 execute computing tasks.

On the one hand, excessive transient current will cause overload operation of many loads on the integrated circuit, resulting in losses of these loads, such as overheating of the internal environment of the integrated circuit. On the other hand, excessive transient current will also cause an instant drop in the supply voltage. If the voltage is lower than some threshold voltage, it will cause functional errors of the internal components of the integrated circuit, bringing serious consequences. Therefore, controlling transient current is a very critical issue in integrated circuits.

In order to solve the aforementioned problems, embodiments of the present application provide a transient current control method, which can control the transient current while ensuring the performance of the integrated circuit.

In order to illustrate the implementation of the embodiment of the present application, please refer to Figures 4-6. Figure 4 shows a flow chart of the transient current control method provided by the embodiment of the present application; Figure 5 exemplarily shows the implementation of the present application. A schematic diagram of the relationship between the data processing unit loading tasks and time for the transient current control method provided in the example;

FIG. 6 is a schematic diagram illustrating the change of the transient current when the data processing unit loads a task under the transient current control method provided by the embodiment of the present application.

As shown in Figure 4, the transient current control method provided by the embodiment of the present application is suitable for the resource allocation module of the integrated circuit and may include the following steps:

In step S10, a data processing unit calling request is received.

It is easy to understand that the data processing unit call request is sent by the handler through the processor.

It should be noted that when multiple data processing unit call requests are received, the resource allocation module receives them one by one. This application explains based on the currently received data processing unit call request.

In step S11, based on the data processing unit calling request, an extended calling time interval between each data processing unit that currently needs to be called is determined, and the extended calling time interval is greater than the standard calling time interval.

The data processing unit 02 that needs to be called is determined based on the data processing unit call request. It is easy to understand that one data processing unit call request needs to call multiple data processing units 02 according to the computing task requirements that need to be completed.

Each data processing unit 02 needs to be loaded in sequence to complete the call, so there will be a call time interval between each data processing unit 02. Therefore, the call time interval needs to be determined. In order to control the transient current, the call time interval is to extend the call time interval. .

It should be noted that the standard calling time interval is determined during integrated circuit design. When each data processing unit 02 loads and performs computing tasks one by one, the time interval between adjacent data processing units 02 is triggered.

The extended calling time interval is greater than the standard calling time interval. Specifically, it can be determined as an integer multiple of the standard calling time interval as needed, such as: 2 times, 3 times, etc.

In this way, the calling time interval can be extended by just a very simple operation.

In a specific implementation, extending the calling time interval includes preset extending the calling time interval, that is, extending the calling time interval determined in advance. As long as it is determined that the calling time interval needs to be extended, the calling time interval can be preset to be extended, so that Determination of extended call intervals is achieved very quickly.

When presetting, you can increase the integer multiple of the standard calling time interval according to the standard calling time interval to obtain the preset extended calling time interval. In this way, it can be ensured that only one data processing unit 02 is triggered within an extended calling time interval. Slow down the rising trend of transient current and ensure the normal operation of the internal devices of the integrated circuit.

Of course, in other specific implementations, the extended call time interval also includes non-preset extended call time intervals, which are temporarily determined as needed. For example, different extended call time intervals can be determined based on different requests. For example, the software program can determine different extended call time intervals based on the received The number of data processing unit call requests is set by itself.

In step S12, calling requests are sent to each of the data processing units in sequence according to the extended calling time interval.

Extend the calling time interval to the standard calling time interval and further extend the original triggering time of the next data processing unit 02, that is, ensure that the next data processing unit (DU1 shown in Figure 5) is triggered and started. At that time, the previous data processing unit (DU0 shown in Figure 5) has basically reached stable operation within the extended calling time interval, so that there is only one or a smaller number of data processing units 02 loading and starting at the same time.

When the extended call time interval is equal to or greater than the load start time of one data processing unit 02, there is only one load start of the data processing unit 02 within the extended call time interval; when the extended call time interval is greater than the standard call time interval but less than one During the loading start time of data processing unit 02, within the extended call time interval, the number of data processing units 02 that load and start at the same time is greater than 1, but less than the number at the standard call time interval.

By staggering the triggering runtimes of the various data processing units 02 so that only a smaller number of starting data processing units 02 are included in an extended call time interval, the transients generated during an extended call time interval are The current is only generated by a small number of data processing units 02, and each data processing unit 02 is executed one after another according to the extended calling time interval. The changing trend of the transient current will be slow and will not change greatly.

As shown in Figure 5, ST in the figure refers to the extended call time interval. Similarly, the extended call time interval accounts for a very small proportion in the total time range required when multiple data processing units 02 work simultaneously.

Specifically, when the data processing unit 02 is working, since the ST time period is greater than the standard calling time interval, within an ST time period, the number of loaded and started data processing units 02 is small, and the transient current generated is less data. The processing unit 02 is generated. When multiple data processing units 02 need to be called to work, the huge transient current generated due to the simultaneous interactive loading and startup of multiple data processing units 02 within the same window period can be mitigated, and power consumption can be reduced. At the same time, the performance of the integrated circuit is guaranteed.

In one embodiment, please refer to FIG. 6 , which is a schematic diagram of the change of the transient current when the data processing unit loads a task under the transient current control method provided by the embodiment of the present application.

As shown in the figure, when the same data processing unit 02 performs a computing task, since the transient current control method provided by the embodiment of the present application extends the time interval between the startup of adjacent data processing units 02, when the data processing unit 02 02 When the load is triggered by a computing task, the transient current generated in the transient current control method provided by the embodiment of the present application rises slowly. In this way, the situation of huge transient currents generated due to the short time interval when multiple data processing units 02 are triggered and started by the computing task is alleviated, thereby providing a load startup for each data processing unit 02 that performs the computing task. A stable working environment ensures that the data processing unit 02 can work normally.

Therefore, the transient current control method provided by the embodiment of the present application increases the probability of staggering the loading startup time of each data processing unit that needs to be called by extending the time interval when the data processing unit 02 performs the computing task, so as to reduce the risk of the data processing unit being called. The called data processing unit has the possibility of loading and starting other data processing units at the same time from startup to reaching a stable working state, thereby reducing the possibility that the transient current will increase instantaneously when multiple data processing units are started at the same time and damage the performance of the integrated circuit chip. situation occurs, reduce the loss of the load, improve the performance of the internal components of the integrated circuit, and extend the service life of the integrated circuit.

In order for the resource allocation module to more conveniently manage the startup time of the data processing unit, in some embodiments, please refer to FIG. 7 , which exemplarily shows another flow chart of the transient current control method provided by the embodiment of the present application. .

As shown in the figure, in order to determine the extension of the calling time interval, the transient current control method provided by the embodiment of the present application may also include the following steps:

In step S110, the number of data processing units that currently need to be called is determined according to the data processing unit calling request.

A data processing unit call request may only call one data processing unit DU to perform a computing task, or it may call two data processing units 02 or more data processing units 02 to perform a computing task. Therefore, it needs to be based on the data first. The processing unit call request determines the number of data processing units 02 that need to be called.

In step S111, it is determined whether the number of the data processing units is greater than a predetermined number. When the number of the data processing units is greater than the predetermined number, step S112 is executed; otherwise, step S113 is executed.

Based on the determined number of data processing units 02, determine whether it is greater than the predetermined number. If it is greater, then execute step S112 to extend the calling time interval between each data processing unit to prevent too many data processing units that are starting to load at the same time; Otherwise, step S13 is executed to determine the standard calling time interval between each data processing unit.

It should be noted that the predetermined number is an allowable value for the number of data processing units 02 that are in the startup loading state at the same time.

Before determining the extended time interval, the data processing unit 02 that needs to be called is judged, and the extended call time interval is accurately set based on the judgment result. In this way, the call to the data processing unit 02 can be more flexibly controlled.

If the predetermined number is too small, so that only a small number of data processing units need to be called, the calling time interval will also be extended. On the one hand, the control amount of the transient current is limited, and on the other hand, the startup time will be extended. In order to fully reflect For the control effect of transient current, in a specific implementation, the predetermined number can be at least 16, such as: 20, 80, etc., when the data processing unit call request is determined based on the number of computing tasks, only When less than a predetermined number of data processing units 02 are called, there is no need to extend the calling time interval.

In step S112, the extended call time interval between the respective data processing units is determined.

When the number of the data processing units is greater than the predetermined number, the calling time interval between each data processing unit is determined to be the extended calling time interval.

Of course, when subsequent calls are made to each data processing unit, the call request will be sent according to the extended call time interval.

In step S113, the standard calling time interval between the respective data processing units is determined.

When the number of the data processing units is greater than the predetermined number, the calling time interval between the respective data processing units is determined to be the standard calling time interval.

Of course, when subsequent calls are made to each data processing unit, the call request will be sent according to the standard calling time interval.

When the received data processing unit call request is to call less than or equal to the predetermined number of data processing units 02, transient current superposition will not occur within the original window period. At this time, the resource allocation module 02 There is no need to set the extended calling time interval, and the computing tasks can be directly assigned to the data processing unit 02.

When the received data processing unit calling request is to call more than a predetermined number of data processing units 02, the calling time interval is set to extend the triggering start time of two adjacent data processing units 02.

Therefore, when the data processing unit call request requires the resource allocation module 01 to call a large number of data processing units 02, the transient current control method provided by the embodiment of the present application is implemented, the transient current control mode is entered, and each data processing unit that needs to be called is staggered The calling time of 02 slows down the rise of transient current. When only a small number of data processing units 02 are needed, the calling method of the device itself is used, that is, the resource allocation module 01 directly sends a calling request to the data processing unit 02 without going through the transient current control provided by the embodiment of the present application. method, enter the transient current control mode, and then send a call request to the data processing unit 02. The sending of call requests can be controlled more flexibly.

In this way, when transient current control is required, the calling time interval can be extended to ensure the control effect while reducing unnecessary control and achieving more flexible control of the data processing unit 02 to perform computing tasks.

Of course, in other embodiments, regardless of the number of data processing units 02 required, the transient current control method provided by the embodiment of the present application can also be implemented, enter the transient current control mode, and realize the scheduling of the data processing units. This saves judgment time and also enables control of transient current.

In some embodiments, in order to improve the convenience of control and reduce the difficulty of adjusting the hardware structure, delay blocking software can be used to determine the extended call time interval between each data processing unit according to the data processing unit call request.

Use software programs to adjust the call interval extension. Based on the call request of the data processing unit, the delay blocking software determines the call interval extension, and then controls the call request to be sent to the data processing unit when the call interval is extended every interval. In this way, Without adding hardware facilities, it is more convenient and flexible to extend the call interval setting.

Of course, in other embodiments, the hardware facilities of the integrated circuit can also be changed, and hardware devices used for delay can be added to provide an extended call time interval for the integrated circuit device when it is working.

In this way, enough time can be reserved to ensure that the number of data processing units in the loading and startup state at the same time is small, thereby slowing down the impact of transient current and protecting the normal operation of the device.

In some embodiments, in order to achieve the convenience of sending call requests to each of the data processing units according to the extended call time interval, please refer to Figure 8. Figure 8 exemplarily shows the transient current control provided by the embodiment of the present application. A flowchart of the steps for sending a method call request.

As shown in the figure, in the transient current control method provided by the embodiment of the present application, the call request sending step may include:

In step S120, send the call request to the previous data processing unit in each of the data processing units, start the time interval timing, and stop sending the call to the later data processing unit in each of the data processing units. ask.

After completing the sending of the call request of the previous data processing unit, it is necessary to determine the timing of sending the call request of the subsequent data processing unit, so start the time interval timing. Of course, it is also necessary to stop sending the call request to each of the subsequent data processing units. The data processing unit sends the calling request.

Specifically, timing can be implemented through an existing timer in the resource allocation module.

In step S121, it is determined whether the time interval timing is equal to the extended calling time interval. If the determination result is yes, step S122 is executed; otherwise, step S123 is executed.

In step S122, the calling request is sent to the later data processing unit in each of the data processing units, and step S124 is executed.

When the time interval is equal to the extended calling time interval, the calling request is sent to the later data processing unit in each of the data processing units.

In step S123, the calling request is not sent to the later data processing unit among the respective data processing units.

When the time interval timing is not equal to the extended calling time interval, the calling request is not sent to the later data processing unit in each of the data processing units.

Of course, it is necessary to continue to wait and judge until the time interval is equal to the extended calling time interval, and step S122 is executed.

In step S124, it is determined whether the sending of the call request of each data processing unit is completed. If yes, step S126 is executed. If not, step S125 is executed.

In step S125, the latter data processing unit is regarded as the new previous data processing unit, and step 120 is executed.

In step S126, it ends.

In this way, it is easy to stagger the execution time of each data processing unit, so that within an extended call time interval, only a small number of data processing units are loaded and started, and the changing trend of the transient current is controlled to rise slowly, protecting The performance of the internal components of an integrated circuit.

In order to facilitate the control of sending call requests to the data processing unit, in a specific implementation, the call request sending register can be used:

To this end, start the time interval timing. You can stop sending the call request to the later data processing unit in each of the data processing units by setting the state of the call request sending register to the blocking state. When the time interval counts, When equal to the extended calling time interval, the calling request can be sent to the latter data processing unit among each of the data processing units by setting the state of the calling request sending register to a non-blocking state.

In this way, by setting the state of the call request sending register to realize the sequential sending of the call request of the data processing unit, it will not affect the design of the internal circuit structure of the integrated circuit, and can also assist in the allocation of computing tasks of the resource allocation module 01, ensuring that the internal device performance.

In order to solve the aforementioned problems, embodiments of the present application also provide a transient current control device, which can be considered as a functional module required to implement the transient current control method provided by the embodiments of the present application. The device content described below may be mutually referenced with the method content described above.

As an optional implementation, FIG. 9 shows an optional structural block diagram of the transient current control device provided by the embodiment of the present application.

As shown in Figure 9, the transient current control device may include:

The receiving module 900 is adapted to receive a data processing unit call request;

The time interval determination module 901 is adapted to determine the extended call time interval between each data processing unit that currently needs to be called based on the data processing unit call request, and the extended call time interval is greater than the standard call time interval;

The sending module 902 is adapted to send calling requests to each of the data processing units in sequence according to the extended calling time interval.

The probability of staggering the loading and start-up times of each data processing unit that needs to be called can be increased to reduce the possibility that other data processing units are loaded and started at the same time during the period from startup to stable working state of the data processing unit being called, thereby reducing When multiple data processing units are started at the same time, the transient current increases instantaneously and destroys the performance of the integrated circuit chip. It reduces the loss of the load, improves the performance of the internal components of the integrated circuit, and extends the service life of the integrated circuit.

In one implementation, the time interval determination module 901 is adapted to determine, based on the data processing unit call request, the extended call time interval between each operating unit module that currently needs to be called, including:

The number of data processing units that currently need to be called is determined according to the data processing unit calling request; when the number of data processing units is greater than a predetermined number, an extended calling time interval between each data processing unit is determined.

When the GPGPU is calculating a computing task, the data processing unit call request received by the resource allocation module 02 may include a request to call only one data processing unit to perform the computing task, or may be a request to call two data processing units or more data processing units. Therefore, the data processing unit that needs to be called can be judged before determining the extended time interval, and the extended calling time interval can be accurately set based on the judgment result, which can more flexibly control the calling of the data processing unit unit.

Among them, the call requests of each data processing unit are received simultaneously.

Of course, in some embodiments, the extended call time interval obtained in the time interval determination module 901 can be determined by using delay blocking software according to the data processing unit call request to determine the extended call time interval between each data processing unit. .

Using software programs to adjust the extension of the call time interval can achieve a more flexible setting of the call time without adding hardware facilities.

In other embodiments, the extended calling time interval may also include a preset extended calling time interval.

That is, in addition to being set by the software program according to the number of call requests received by the data processing unit, the extended calling time interval can also be preset manually in advance. When preset, the standard calling time interval can be increased by an integer of the standard calling time interval. times to obtain the preset extended calling time interval. This ensures that within an extended calling time interval, only one data processing unit is gradually executing computing tasks to a stable state, thereby slowing down the rising trend of transient current and ensuring that the integrated circuit the normal operation of the internal devices.

It should be noted that the extended calling time interval can be an integer multiple of the standard calling time interval. In this way, enough time can be reserved to ensure that during the period when the operation of the first data processing unit reaches stability, the other data processing unit is not triggered to start, thereby mitigating the impact of transient current and protecting the normal operation of the device.

The sending module 902 is also suitable for:

Send the call request to the previous data processing unit in each of the data processing units, and start time interval timing;

When the time interval timing is equal to the extended calling time interval, the calling request is sent to the later data processing unit in each of the data processing units, and the later data processing unit is used as the new previous one. The data processing unit waits until the sending of the call request of each data processing unit is completed.

In this way, the execution time of each data processing unit can be staggered, so that within an extended call time interval, only one data processing unit is allowed to execute until stable, and the changing trend of the transient current is controlled to rise slowly, protecting the performance of the internal devices of the integrated circuit.

In order to implement the sending of call requests to each data processing unit according to the extended calling time interval, in a specific implementation, the sending module 902 is adapted to send calls to each of the data processing units in sequence according to the extended calling time interval. Requests include:

Stop sending the call request to the latter data processing unit in each of the data processing units by setting the state of the call request sending register to the blocking state;

When the time interval timing is equal to the extended calling time interval, the calling request is sent to the latter data processing unit in each of the data processing units by setting the state of the calling request sending register to a non-blocking state.

In this way, by setting the state of the register, the data processing unit call request is sent one after another, which will not affect the design of the internal circuit structure of the integrated circuit, and can also assist in the allocation of computing tasks of the resource allocation module 01, ensuring the performance of the internal devices of the integrated circuit. .
