[0020] In order to better understand the technical solutions provided by the embodiments of this specification, the technical solutions of the embodiments of this specification are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0021] In this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements limited by the statement "comprise one..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements. The term "more than two" includes two or more than two situations.

[0022] In the traditional computing architecture, a computer includes a processor and a memory. The processor is used to perform data calculations, and the memory is used to store data. When the computer performs data processing, it needs to obtain data from the memory, transmit it to the processor for data calculation, and store the calculated data back into the memory. For example, in the process of neural network calculation, when the forward propagation calculation is performed in the processor, the input value is calculated in the neurons of the input layer, the calculation result is obtained, and the calculation result is stored in the memory. When the activation function is used to convert the calculation result, the processor extracts the calculation result from the memory, and further uses the activation function to convert the calculation result to obtain the final result value. Since the numerical values ​​in the general neural network calculation process are relatively large, the frequent transmission between the processor and the memory increases the time of data processing and increases the computing power consumption of the computer.

[0023] Figure 1 The structure of an in-memory computing device provided by an embodiment of the present application is shown. Figure 1 .like Figure 1 As shown, the present application provides an in-memory computing device, including at least one storage computing block 11, the storage computing block includes a connected storage computing module 12 and an activation module 13; the storage computing module 12 includes a first computing unit 121 and multiple storage computing units 122, and the storage computing units in the same storage computing module are all connected to the first computing unit; the activation module 13 includes multiple activation units 131, the activation unit 131 includes an activation function, the first computing unit 121 is connected to the activation unit 131, and the activation function is used to perform an activation operation on the operation result output by the first computing unit 121 to obtain a result value of the in-memory computing device.

[0024] This embodiment designs an in-memory computing device, which is a new type of computing architecture that aims to integrate data processing and storage functions in the same physical location, that is, the storage and computing block can perform data computing and data storage. The storage and computing block of the in-memory computing device mainly includes a connected storage and computing module and an activation module, which are used to perform neural network tasks.

[0025] The storage and calculation module performs in-memory calculations on input values ​​when performing neural network tasks. The in-memory module includes a first calculation unit and multiple storage and calculation units. The multiple storage and calculation units perform calculations as each neuron in the neural network task. The first calculation unit is used to simultaneously connect multiple storage and calculation units, and is used to perform comprehensive calculations on the results calculated by each storage and calculation unit. The result obtained by the calculation is used as the calculation result of the storage and calculation unit. The storage and calculation device proposed in this embodiment can directly input the calculation result into the activation unit for activation calculation after the storage and calculation unit calculates and obtains the calculation result, without inputting the calculation result into the memory, and can further perform the activation operation after performing the storage and retrieval operations. The in-memory calculation device of this embodiment can perform neural network tasks without the participation of the memory, and can effectively reduce the delay and power consumption when processing neural network tasks.

[0026] In some embodiments, the storage and computing unit stores stored data, and the storage and computing unit is used to determine the product result of the stored data and the input data after obtaining the input data. The first computing unit is used to accumulate the product results output by multiple storage and computing units to obtain the computing result.

[0027] Each storage unit can be used as a storage unit, which has stored data stored inside and can further perform calculation functions. After the storage unit obtains the input value, the storage unit can perform a calculation process in combination with the input value and the stored data stored in itself. For example, the storage unit can perform a product calculation of the input value and the stored data, and the obtained product calculation result is used as the calculation result of the storage unit itself.

[0028] The first operation unit is connected to a plurality of storage and calculation units. After each storage and calculation unit obtains a calculation result, the first operation unit obtains the calculation results of each operation unit connected thereto and performs a comprehensive calculation. Exemplarily, the first operation unit may be an addition tree, which accumulates the obtained calculation results, and the obtained accumulated value is used as the calculation result of the addition tree.

[0029] In some embodiments, the result value includes a first result value and a second result value; The activation function is used to identify the identification value in the identification bit of the operation result. If the identification value meets the first condition, the activation function is used to perform a first activation operation on the operation result to obtain a first result value; if the identification value meets the second condition, the activation function is used to perform a second activation operation on the operation result to obtain a second result value.

[0030] After the storage module outputs the operation result, the activation unit is used to perform an activation operation on the operation result using the activation function. The activation unit in this embodiment can perform at least two activation operations on the operation result. The first activation operation can directly output the operation result output by the storage module, and the second operation result can set the operation result output by the storage module to 0. Exemplarily, the activation function contained in the activation unit can be a rectified linear unit (ReLU) function, and the activation operation performed can effectively solve the gradient vanishing problem, accelerate model training, and improve model sparsity and accuracy.

[0031] The activation unit has certain judgment conditions when determining whether to execute the first activation operation or the second operation result. When the first condition is met, the first activation operation is executed, and when the second condition is met, the second operation result is executed, so that the activation unit can select the appropriate type of activation operation according to the operation result of the storage module. In this embodiment, the activation unit realizes the selection of the activation operation by identifying the value of the operation result identification bit, so as to reasonably select the type of activation operation. In some embodiments, the identification bit includes the highest bit of the operation result.

[0032] In the process of judging the value in the identification bit, in some embodiments, the first condition includes the identification value being 1, and the first activation operation is to set the operation result to 0; the second condition includes the identification value being 0, and the second activation operation is to set the operation result as the result value of the activation operation.

[0033] The activation unit can complete multiple types of activation operations by judging the value of the identification bit.

[0034] In some embodiments, each storage and calculation module is connected to a corresponding activation unit, and the first calculation unit is connected one-to-one with the activation unit.

[0035] like Figure 1 As shown, there is a one-to-one correspondence between the storage and computing module 12 and the activation unit 131. The calculation result obtained by each storage and computing unit 122 can be directly input into the corresponding activation unit 131 for activation operation, thereby ensuring the orderly execution of the in-memory calculation in the storage and computing block 11.

[0036] Figure 2 The structure of an in-memory computing device provided by an embodiment of the present application is shown. Figure 2 For example, Figure 2 As shown, in the same storage computing block, multiple storage computing units 122 are included. When performing neural network tasks, the storage computing units correspond to the multi-level neurons in the neural network structure. Therefore, in each storage computing block, each storage computing unit is set with a level value. The input value can perform multi-level operations through the storage computing unit. Each storage computing unit is sorted according to the level value, which can ensure that after the input value is input into the storage computing block, the input value can be quickly calculated through the storage computing unit in sequence.

[0037] In some embodiments, each storage and calculation block includes storage and calculation units with multiple levels of values, and the storage and calculation units are arranged according to the level value. The level value of the storage and calculation unit can be used to indicate the priority of the storage and calculation unit when executing the calculation. The calculation result of the high-level value storage and calculation unit can be used as the weighted value of the data stored in the low-level value storage and calculation unit. For example, Figure 2 As shown, the multiple storage and computing units 122 included in the storage and computing module 12 are respectively set to different levels: level 1, level 2, level 3 and level 4. The calculation priority of the storage and computing unit 122 at level 1 is the highest, and the calculation priority of the storage and computing unit 122 at level 4 is the lowest. The storage and computing units 122 can be controlled to start calculation in sequence according to the priorities of the storage and computing units 122 at level 1, level 2, level 3 and level 4.

[0038] In some embodiments, adjacent storage and computing units in different storage and computing modules are connected.

[0039] In adjacent storage and computing modules, storage and computing units of the same level value are connected.

[0040] When there are many input values, in order to realize parallel operation of input values, such as Figure 2 As shown, the in-memory computing device of this embodiment includes multiple memory computing blocks, and the memory computing units of the same level value in each memory computing block are connected. In order to improve efficiency, the input values ​​can be input into different memory computing units of the same level for separate calculations, which can effectively reduce the execution time when performing neural network tasks.

[0041] In some embodiments, an in-memory computing device, such as Figure 2As shown, it also includes: an input driver module 21, a word line driver module 22, a bit line driver module 23 and a row decoder 24; the input driver module 21 is connected to the storage and calculation unit 122, and the input driver module is used to input input data to the storage and calculation unit; the word line driver module 22 is connected to the storage and calculation unit 122, and the word line driver module is used to enable at least one storage and calculation unit when receiving a control signal; the bit line driver module 23 is connected to the storage and calculation unit 122, and the bit line driver module is used to write stored data to the storage and calculation unit; the row decoder 24 is connected to the word line driver module 22, and is used to convert the address signal of the storage and calculation unit into a control signal.

[0042] This embodiment further describes other related components of the in-memory computing device. The in-memory computing device is further provided with an input driver module, a word line driver module, a bit line driver module and a row decoder, which are used to support the memory computing module and the activation module to perform in-memory computing. Among them, the input driver module 21, the word line driver module 22, the bit line driver module 23 and the row decoder 24 receive timing control 25 from the clock.

[0043] The present application embodiment discloses an in-memory computing method, which is applied to an in-memory computing device, such as Figure 3 The flowchart of an in-memory computing method shown in FIG. 1 includes: Step 301, calling a target storage and computing block according to a received control signal, where the target storage and computing block is a storage and computing module corresponding to the instruction sequence of the control signal; Step 302, inputting input data to the storage unit in the target storage module according to the control signal; Step 303, obtaining result values ​​obtained by the target storage calculation module and the target activation module respectively, and the target activation module is used to activate the calculation result output by the target storage calculation module.

[0044] During the application of the in-memory calculation method, the storage unit in the storage calculation module stores stored data, and the target storage calculation block is called according to the control signal, so that the storage calculation module and the activation module in the target storage calculation block are in an activated state. Input data is input into the storage calculation unit in the target storage calculation module, and the storage calculation unit performs calculations based on the input data and the stored data, and the result values ​​calculated by multiple storage calculation units are comprehensively calculated by the first calculation unit, and the result of the comprehensive calculation is used as the calculation result of the target storage calculation module. After the target activation module obtains the calculation result from the target storage calculation module, it directly performs the activation operation. The target activation module can directly complete the activation function without the need for repeated data transmission by external devices, which can effectively reduce the delay and power consumption of the in-memory computing device when processing neural network tasks.
