Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope of the present disclosure.

Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
In the deep learning algorithm, a mainstream language model (such as BERT, ERNIE and the like) includes a large amount of matrix multiplication, vector calculation and other operations, a mainstream machine vision model (such as RESNET, MASK-RCNN, YOLO, SSD and the like) also includes a large amount of convolution operations, and the convolution operations are usually realized by converting into matrix operations. Therefore, the deep learning chip generally provides a dedicated arithmetic device such as a matrix multiplication device and a vector calculation device for accelerating the deep learning algorithm.
While providing extremely high computational power for matrix multiplication and vector calculation, these arithmetic devices also consume a large amount of power. Under different scenes and chip heat dissipation conditions, related technicians often need to adjust the power consumption levels of different computing devices according to actual conditions and computing needs, so that the performance reduction of the computing device caused by overhigh power consumption is avoided.
In the related art, for monitoring and adjusting the power consumption of the computing device in the chip, the current change of the whole chip is usually detected through the power management chip of the board card, and the frequency of the whole chip is adjusted accordingly. The method usually needs a host to actively control the frequency switching of the chip, or the frequency switching is carried out through an MCU in the chip, so that the delay is higher; the frequency switching can affect all devices of the whole deep learning chip, and the performance of other modules such as access and control is limited while the power consumption of the arithmetic device such as matrix multiplication and transposition is limited.
The embodiment of the disclosure provides a power consumption control method for an arithmetic device, which evaluates the power consumption level of the arithmetic device by acquiring the number of data request signals in a certain period based on the relationship between the data request signals of input data of the arithmetic device and the power consumption of the device, adjusts the power consumption of the device in a mode of adjusting the working frequency of the arithmetic device, can judge the power consumption of the device efficiently through simple logic, and improve the efficiency of power consumption adjustment.
According to an embodiment of the present disclosure, as shown in fig. 1, there is provided a power consumption control method for an arithmetic device, which may include: step S101, acquiring a first number of data request signals in a power consumption evaluation period, wherein the power consumption evaluation period comprises a plurality of continuous operation periods with a first preset number, and the data request signals are used for requesting input data of an operation device; step S102, acquiring an average power consumption representation value of the operation device in a power consumption evaluation period based on the first quantity; step S103, acquiring a power consumption evaluation result in a power consumption evaluation period based on the average power consumption characterization value and a preset power consumption threshold value; and step S104, adjusting the working frequency of the arithmetic device based on the power consumption evaluation result.
Therefore, the power consumption level of the arithmetic device is evaluated by acquiring the number of the data request signals in a certain period, and the power consumption of the arithmetic device is adjusted in a mode of adjusting the working frequency of the arithmetic device, so that the power consumption of the efficient evaluation device can be judged through simple logic, and the efficiency of power consumption adjustment is improved.
Fig. 2 shows a schematic structural diagram of a chip provided with a power consumption control device according to an embodiment of the present disclosure.
In some embodiments, as shown in fig. 2, the instruction generating device 210 disposed in the chip issues the operation instruction to the instruction parsing device 220, and the instruction parsing device 220 parses the operation instruction to generate a computation enable signal corresponding to at least one operation cycle and a data request signal for requesting computation of each operation cycle. In each operation cycle, the instruction parsing device 220 sends a calculation enable signal and a data request signal to the operation device 230 and the storage device 250, respectively, and the storage device 250 sends input data to the operation device 230 to complete calculation based on the data request signal and stores output data output by the operation device 230.
In some embodiments, the power consumption control device 240 of the embodiments of the present disclosure may be connected to the instruction parsing device 220, so as to implement power consumption control on the computing device 230 corresponding to the instruction parsing device 220. Specifically, in each operation cycle, the instruction parsing device 220 simultaneously sends a data request signal to the power consumption control device 240, and the power consumption control device 240 obtains the power consumption level of the operation device 230 based on the number statistics of the signals.
In some embodiments, the power consumption control device 240 may count the data request signals of each operation cycle within a first preset number of consecutive operation cycles (i.e., power consumption evaluation cycles).
The length of the power consumption evaluation period may be adjusted by setting a first preset number, for example, the first preset number may be set to 8 operation periods. It can be understood that the related art can set the first preset number by itself according to actual requirements and conditions, such as the calculated requirements and the hardware heat dissipation conditions, and the like, without limitation.
In some embodiments, the arithmetic device may include a plurality of arithmetic sub-modules, and obtaining the average power consumption characterizing value of the arithmetic device during the power consumption evaluation period based on the first number may include: acquiring a second number of operation submodules in the operation device in the working state in the power consumption evaluation period based on the first number; and acquiring an average power consumption characterization value of the operation device in the power consumption evaluation period based on the second quantity.
Therefore, the number of the working calculation sub-modules in the calculation device in the period can be obtained based on the number of the data request signals, and the power consumption level of the calculation device in the period is represented by the number of the working calculation sub-modules. Therefore, the power consumption level of the arithmetic device can be efficiently obtained through simple logic operation, the real-time performance is higher, and the occupation of computing resources is less.
An arithmetic device usually includes a plurality of arithmetic sub-modules, and in an arithmetic cycle, if one arithmetic sub-module performs calculation, one or more pieces of input data, each of which is obtained by a different data request signal (that is, the number of input data is the same as the number of data request signals), must be acquired. Therefore, in one power consumption evaluation period, a certain corresponding relation exists between the first number of the data request signals and the second number of the operation sub-modules in the working state. And the average number (namely, the average power consumption characterization value) of the operation sub-modules in the working state in the power consumption evaluation period can characterize the average power consumption level of the operation device in the power consumption evaluation period.
Fig. 3 shows a block diagram of a vector calculation apparatus according to an exemplary embodiment of the present disclosure.
In an exemplary embodiment, the computing device may be, for example, a vector computing device 300 as shown in fig. 3. Vector computing devices are typically used to process operations between vectors or between vectors and scalars. As shown in fig. 3, the vector computing apparatus 300 includes K vector computing sub-modules, and each vector computing sub-module processes an operation between a pair of vectors or a vector and a scalar respectively in one operation cycle, that is, when one vector computing sub-module works, two input data are required to be input to the sub-module at the same time, and each input data corresponds to one data request signal.
Therefore, the corresponding relation exists between the number of the data request signals and the number of the vector calculation sub-modules in the working state, namely the number of the data request signals is 2 times of the number of the vector calculation sub-modules in the working state.
Therefore, by counting the first number of the data request signals in the power consumption evaluation period, the second number of the vector calculation sub-modules in the working state in the power consumption evaluation period can be obtained through the corresponding relation. Furthermore, the power consumption level of the vector computing device in the power consumption evaluation period can be reflected by acquiring the number of vector computing submodules (namely, average power consumption characterization values) which are in the working state in each computing period on average.
Fig. 4 shows a block diagram of a matrix multiplication apparatus according to an exemplary embodiment of the present disclosure.
In an exemplary embodiment, the arithmetic device may be, for example, a matrix multiplication device 300 as shown in fig. 4. The matrix multiplication device shown in fig. 4 includes M × N matrix multiplication submodules, which can support at most one matrix with M row vectors and one matrix with N column vectors to perform matrix inner product operation in one operation cycle, where M and N are positive integers greater than 1.
When the matrix multiplication device is applied to calculate a matrix A with M row vectors and a matrix B with N column vectors (wherein M is more than or equal to 1 and less than or equal to M, and N is more than or equal to 1 and less than or equal to N), M multiplied by N matrix multiplication sub-modules are required to carry out operation simultaneously.
When each matrix multiplication submodule performs operation, input data A (i) and input data B (j) (i belongs to [0, m ], j belongs to [0, n ]) are respectively obtained, each input data corresponds to one data request signal, and when m multiplied by n matrix multiplication submodules are required to perform operation simultaneously, the number of the data request signals is (m + n).
Therefore, it can be seen that, by counting the first number of data request signals (the number of data request signals requesting a (i) and the number of data request signals requesting b (j)) in the power consumption evaluation period, and according to the above correspondence, the second number of matrix multiplication sub-modules in the power consumption evaluation period in the working state can be obtained. Furthermore, by obtaining the number of the matrix multiplication sub-modules (i.e. the average power consumption characterization value) which are in the working state in each operation cycle on average, the power consumption level of the matrix multiplication device in the power consumption evaluation cycle can be reflected.
Fig. 5 shows a block diagram of a power consumption control apparatus according to an embodiment of the present disclosure.
In some embodiments, the power consumption control apparatus 500 may first count the number of data request signals in each operation cycle through the counting module 510, so as to obtain the number of operation sub-modules (denoted as busy _ cnt) in an operating state in the operation cycle based on a predetermined corresponding relationship and send the number to the register for storage.
In some embodiments, each busy _ cnt for a first preset number of cycles may be stored in a register, then input to an adder for summation, then input to a divider for obtaining a corresponding average power consumption characterization value.
In some embodiments, it may be preferable to set the first preset number to 2 n (n is a positive integer), so that the average power consumption characteristic value (denoted as busy _ cnt _ avg) can be obtained by first performing an arithmetic right shift on each busy _ cnt by n bits (which is equivalent to dividing by a first preset number) by using the shift register 520 shown in fig. 5, and then transmitting each shifted busy _ cnt to the adder 530 for summing. Therefore, division calculation operation can be conveniently carried out through the shift register, the calculation efficiency is improved, and the calculation resources are saved.
In some embodiments, adjusting the operating frequency of the computing device based on the power consumption assessment result may include: adjusting a power consumption control signal value represented by a binary system based on a power consumption evaluation result, wherein the power consumption evaluation result indicates whether the power consumption of the computing device exceeds a preset power consumption threshold value, and the power consumption control signal value comprises a plurality of numerical values of a second preset number; and controlling the working frequency of the operation device in a next second preset number of operation cycles after the power consumption control signal value is adjusted based on a plurality of numerical bits in the adjusted power consumption control signal value, wherein the second preset number is less than or equal to the first preset number, the plurality of numerical bits comprise a first numerical bit of which the numerical value is the first value, and the number of the first numerical bit is used for indicating the number of operation cycles in which the operation device stops working in the next second preset number of operation cycles.
Therefore, a binary power consumption control signal value is adjusted through the power consumption evaluation result, the working frequency of the operation device is correspondingly adjusted based on the signal value, the operation can be realized through the existing components (such as a register, a comparator and the like), the structure is simple, and the cost is saved; meanwhile, the power consumption control logic is simple, and the efficiency and the real-time performance of power consumption adjustment can be further improved.
In some embodiments, as shown in fig. 5, the preset power consumption threshold may be stored in the first register 550 and support the related technical personnel to maintain the same based on actual situations, so that the value thereof is not limited herein.
The power consumption evaluation result may be obtained by comparing the average power consumption characterizing value (busy _ cnt _ avg) obtained from the adder 550 and the preset power consumption threshold value obtained from the first register 550 by the comparator 540. After obtaining the power consumption evaluation result, the comparator 540 sends the power consumption evaluation result to the second register 560, and the second register 560 adjusts the power consumption control signal value stored in the second register 560 according to the power consumption evaluation result.
In some embodiments, the plurality of numerical bits further includes a second numerical bit having a second value, and obtaining the power consumption evaluation result in the power consumption evaluation period based on the average power consumption characterizing value and the preset power consumption threshold value may include: responding to the fact that the average power consumption characteristic value is larger than or equal to a preset power consumption threshold value, and determining that the power consumption evaluation result is that the power consumption of the operation device is too high; and wherein the determining the binary-represented power consumption control signal value based on the power consumption assessment result may comprise: and adjusting a second numerical bit in the power consumption control signal value to the first numerical bit in response to determining that the power consumption evaluation result is that the power consumption of the arithmetic device is too high.
In some embodiments, as shown in fig. 5, the second register 560 in the power consumption control apparatus 500 may store a power consumption control signal value having a second preset number of bits. The power consumption control signal value has a first value bit having a first value and a second value bit having a second value. The number of the first numerical bits indicates the number of cycles for the computing device to stop working in the power consumption adjustment period (i.e. the next second preset number of computing periods) after the power consumption control signal value is adjusted.
The second predetermined number needs to be less than or equal to the first predetermined number, thereby avoiding the need to evaluate and adjust the power consumption again when the adjustment effect has not yet occurred. It is understood that the second preset number can be set by a person skilled in the relevant art according to actual requirements, and is not limited herein.
For example, the first value may be "1", and the second value may be "0"; alternatively, the first value may be "0" and the second value may be "1"
In some embodiments, the power consumption control signal value stored in the second register 560 may be an 8-bit binary data (denoted as stall _ mask [7:0]), and its initial value is "00000000" (i.e., each bit is a second value), and the second register 560 may be an 8-bit register.
When the comparator 540 determines that the average power consumption characterization value (busy _ cnt _ avg) is greater than or equal to the preset power consumption threshold value through comparison, the result is correspondingly transmitted to the second register 560. The second register 560 adjusts, based on the result, one bit having an original value of "0" among the power consumption control signal values (stall _ mask [7:0]) maintained therein to "1", for example, the stall _ mask [7:0] is adjusted from an initial value of "00000000" to "00000001", and the power consumption control signal value indicates that the operation device stops operating in 1 operation cycle out of 8 operation cycles after the adjustment; for another example, the value of the power consumption control signal may indicate that the arithmetic device stops operating when 3 arithmetic cycles out of the adjusted 8 arithmetic cycles are set to "00000111" by "00000011" in the stall _ mask [7:0 ].
In some embodiments, the plurality of numerical bits further includes a second numerical bit having a second value, and obtaining the power consumption evaluation result in the power consumption evaluation period based on the average power consumption characterizing value and the preset power consumption threshold value may include: responding to the fact that the average power consumption characteristic value is smaller than a preset power consumption threshold value, and determining that the power consumption evaluation result is that the power consumption of the operation device is normal; and wherein the determining the binary-represented power consumption control signal value based on the power consumption assessment result may comprise: and adjusting one first numerical bit in the power consumption control signal value to be a second numerical bit in response to the power consumption evaluation result being that the power consumption of the arithmetic device is normal and the power consumption control signal value comprises the first numerical bit.
In some embodiments, when the comparator 540 determines that the average power consumption characterizing value (busy _ cnt _ avg) is smaller than the preset power consumption threshold value through comparison, the result is correspondingly transmitted to the second register 560. Based on the result, the second register 560 can adjust the power consumption control signal value (stall _ mask [7:0]) to maintain it accordingly.
When the original value in the stall _ mask [7:0] includes "1", a bit whose original value in the stall _ mask [7:0] is "1" may be adjusted to "0". For example, if stall _ mask [7:0] is adjusted from the initial value "00000111" to "00000011", the power consumption control signal value may indicate that the arithmetic device stops operating in 2 arithmetic cycles out of the adjusted 8 arithmetic cycles (3 cycles stop operating every 8 cycles before the adjustment).
In some embodiments, determining the binary-represented power consumption control signal value based on the power consumption evaluation result may further include: and in response to determining that the power consumption evaluation result is that the power consumption of the arithmetic device is normal and each numerical bit in the power consumption control signal value is the second numerical bit, determining that each numerical bit in the power consumption control signal value is still the second numerical bit.
In some embodiments, when the power consumption evaluation result obtained from the comparator 540 is that the average power consumption characterizing value (busy _ cnt _ avg) is smaller than the preset power consumption threshold value, and the original value of the power consumption control signal value stall _ mask [7:0] is the initial value of "000000000000", no adjustment may be made to the power consumption control signal value stall _ mask [7:0], and "000000000000" may still be maintained (i.e. the computing device operates normally in each of the following 8 computing cycles).
In some embodiments, controlling the operating frequency of the arithmetic device in a next second preset number of arithmetic cycles after the adjusting of the power consumption control signal value based on the plurality of numerical bits in the adjusted power consumption control signal value may include: generating an instruction issue blocking signal based on a third number of second numerical bits in the adjusted power consumption control signal value; and sending the instruction issuing blocking signal to an instruction analysis device used for sending the operation instruction to the operation device so as to prevent the instruction analysis device from stopping issuing the operation instruction in a third number of operation cycles in a next second preset number of operation cycles.
Therefore, based on the adjusted power consumption control signal value, an instruction issuing blocking signal is generated, so that the number of the periods for stopping issuing the instruction in the next power consumption adjusting period is reduced, the power consumption level of the operation device is controlled by adjusting the working frequency of the operation device, and the normal operation of other components (such as a storage device, a control device and the like) in the chip is not influenced while the power consumption level of the operation device is effectively controlled.
In some embodiments, as shown in fig. 5, after the power consumption control signal value in the second register 560 is adjusted, the second register 560 generates an instruction issue blocking signal based on the adjusted power consumption control signal value, and sends the instruction issue blocking signal to an instruction parsing apparatus (not shown).
In some embodiments, after receiving the instruction issue blocking signal, the instruction analysis device may know that the instruction (i.e., the calculation enable signal and the data request signal) needs to be stopped to issue in a next second predetermined number of operation cycles, so as to control the operation device to stop working in the cycle.
In some embodiments, after acquiring the information, the instruction parsing device may randomly select a period (the number is the same as the number of the first value in the power consumption control signal value) for stopping issuing the instruction.
In some embodiments, as shown in fig. 5, the second register 560 may also generate an instruction issue blocking signal 502 based on its stored power consumption control signal value 501, for example, if the power consumption control signal value 501 is "00001111", then the corresponding generated instruction issue blocking signal 502 is a corresponding window signal. After receiving the instruction issue blocking signal 502, the instruction analysis device may stop issuing instructions based on 4 operation cycles indicated by the window of the signal.
In some embodiments, the power consumption control method for an arithmetic device of an embodiment of the present disclosure may further include: after the power consumption control signal value is adjusted, responding to a third preset number of operation cycles, and then obtaining an average power consumption representation value of the operation device in the latest power consumption evaluation cycle to determine a power consumption evaluation result of the operation device in the latest power consumption evaluation cycle, wherein the third preset number is greater than or equal to the first preset number; and re-determining the power consumption control signal value based on a power consumption evaluation result of the operation device in the latest power consumption evaluation period.
Therefore, by setting the interval period (that is, the third preset number of operation periods), after the power consumption is adjusted once, the comparison of the power consumption data and the adjustment of the power consumption control signal value in the register are performed after the interval period, so that the frequency of the power consumption adjustment can be controlled based on the interval period, and the power consumption adjustment of the operation device can be made smoother.
In some embodiments, when a third preset number of operation cycles (i.e., interval cycles) are set, the average power consumption characterization value is not compared with the preset power consumption threshold value and the power consumption control signal value is not adjusted in the third preset number of operation cycles after the power consumption control signal value is adjusted once. In the interval period, the arithmetic device operates at the adjusted operating frequency.
In some embodiments, the third preset period may be greater than or equal to the first preset period, so that it can be avoided that when the next comparison is triggered, the obtained average power consumption characterization value is still the result of the last statistics, which affects the power consumption evaluation result and the power consumption adjustment effect of the comparison. It is understood that the third preset number can be set by a person skilled in the art according to actual requirements, and for example, can be an integer multiple of the first preset period, which is not limited herein.
