Problems solved by technology
However, even if parallel computing is used, since the processor is limited by the capacity of internal register resources, the huge amount of data calculation may cause a large amount of data interaction between the processor and the external storage device, thereby reducing the calculation and processing of the device. efficiency
Due to the limited bandwidth of the input / output ("I / O") bus, severe I / O bottlenecks can occur, thus greatly reducing the efficiency of parallel computing
In addition, not only the bandwidth limitation of the I / O bus will become a performance bottleneck, but also a large amount of I / O memory access between the processor and the external storage device will also cause a large calculation and power consumption overhead

Description
technical field [0001] The present disclosure relates generally to the field of data processing. More specifically, the present disclosure relates to an integrated circuit device, an electronic device, a board, and a computing method. Background technique [0002] With the development of the field of artificial intelligence, the amount of computational data involved in large-scale neural networks is increasing, and the requirements for storage capacity are getting higher and higher, such as convolution weight gradients in backpropagation and other operations. In existing computing methods, processors such as a central processing unit (“CPU”) or a graphics processing unit (“GPU”) are usually used for computing. However, even if parallel computing is used, since the processor is limited by the capacity of internal register resources, the huge amount of data calculation may cause a large amount of data interaction between the processor and the external storage device, thereby ...
