Problems solved by technology
[0002] The current calculation process of convolution operation can be performed by the central processing unit or network processor. When the current central processing unit performs a large amount of data operation, the speed is relatively slow; when the current network processor performs convolution operation, the operation steps are more complicated and cannot Give full play to the performance of the network processor

Embodiment Construction
[0024] The following describes the embodiments of the present application in detail.
[0025] see figure 1 , figure 1 It is a structural diagram of a network processor 100 of an electronic device provided in an embodiment of the present application. The network processor 100 includes a buffer 101, a processing engine 110, and the processing engine 110 includes at least one computing unit 111, and an accumulation register 112 and a virtual register 113 corresponding to each computing unit 111, and each computing unit includes a first storage unit A , the second storage unit B, wherein the data bit widths of the first storage unit A and the second storage unit B are the same; The DRAM acquires the image data and convolution kernel data to be processed; stores the data of each pixel of the image data to the buffer 101 in sequence according to the resolution of the image data, and repeatedly caches each pixel in the buffer according to the preset buffer strategy. The data of co...

The embodiment of the invention discloses a convolution operation method and a related product, and is applied to electronic equipment, and the method comprises the steps that the electronic equipmentdetects whether a currently processed pixel point set is the last to-be-processed pixel point set in a pixel point set sequence of a target image or not; if not, executing a preset convolution kerneltraversal operation process to obtain at least one output value corresponding to each pixel point in the currently processed pixel point set, and updating the currently processed pixel point set intoa next to-be-processed pixel point set in the pixel point set sequence; if yes, executing the convolution kernel traversal operation process to obtain at least one output value corresponding to eachpixel point in the currently processed pixel point set; and generating a convolution operation result according to the at least one output value corresponding to each pixel point. According to the embodiment of the invention, the performance of the network processor can be brought into full play, and the convolution operation speed is improved.
