Problems solved by technology

From the perspective of application fields, there are two main routes for chips: one is the general-purpose chip route, such as the central processing unit (Centre Processing Unit, CPU), etc., which can provide great flexibility, but have effective computing power when dealing with specific field algorithms. The other is a dedicated chip route, such as tensor processing unit (TPU), etc., which can exert high effective computing power in some specific fields, but in the face of flexible and more general areas, they have poor or even incapable processing

Embodiment 1

[0066] The first input matrix can be a 3x6 matrix, for example

[0067] A plurality of operation units of the data operation circuit is a 3x6 array. The preset multiplication coefficient ai is 0.

[0068] When the instruction is to implement the ReLU function for each element of the first input matrix, the operation realized by the data operation unit is: the data operation unit PU in the first row and the first column receives the first row and the first column of the first input matrix Store the data a11 (the value is 0) into Rin1, compare the data a11 with the first preset constant (can be set to 0) stored in the first constant register CO, and control the switch S0 to select 1 according to the comparison result that the two are equal If the number port is connected, the output of Rout is Rin1, which is 0. The data operation unit PU in the first row and the second column receives the data a12 (the value is 7) in the first row and the second column of the first input mat...

Embodiment 2

[0071] The first input matrix can be a 3x6 matrix, for example

[0072] A plurality of operation units of the data operation circuit is a 3x6 array. The preset multiplication coefficient ai is 2.

[0073] When the instruction is to realize the PReLU function function for each element of the first input matrix, the operation realized by the data operation unit is:

[0074] The data operation unit PU in the first row and the first column receives the data a11 (the value is 0) in the first row and the first column of the first input matrix and stores it in Rin1, and combines the data a11 with the first preset stored in the first constant register CO. Set a constant (can be set to 0) for comparison, and according to the comparison result that the two are equal, the control switch S0 selects port 1 to be connected, then Rout outputs Rin1, which is 0. The data operation unit PU in the first row and the second column receives the data a12 (the value is 7) in the first row and the...

Embodiment 3

[0077] The first input matrix can be a 3x6 matrix, for example

[0078] If the arithmetic unit array in the data operation circuit is a 3x3 array, then the matrix will be divided into 3*3 groups for calculation.

[0079] When the instruction is to implement the ReLU function for each element of the first input matrix, the operation realized by the data operation unit is: the data operation unit PU in the first row and the first column receives the first row and the first column of the first input matrix Store the data a11 (the value is 0) into Rin1, compare the data a11 with the first preset constant (can be set to 0) stored in the first constant register CO, and control the switch S0 to select 1 according to the comparison result that the two are equal If the number port is connected, the output of Rout is Rin1, which is 0. By analogy, the arithmetic unit at the third row and the third column obtains the data at the third row and the third column of the output matrix.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data computing circuit, a data processing device, a chip, a card board and electronic equipment. Background technique [0002] With the development of science and technology, human society is rapidly entering the age of intelligence. An important feature of the intelligent era is that people obtain more and more types of data, and the amount of data obtained is increasing, while the requirements for processing data speed are getting higher and higher. [0003] Chips are the cornerstone of data processing, which fundamentally determines people's ability to process data. From the perspective of application fields, there are two main routes for chips: one is the general-purpose chip route, such as the central processing unit (Centre Processing Unit, CPU), etc., which can provide great flexibility, but have effective computing power when dealing with specific field algorit...
