Abstract: A hardware architecture that may include: a host, a frontal engine, a parietal engine, a renderer engine, an occipital engine, a temporal engine, and a memory. The frontal engine may obtain a 5D tensor from the host and divide it into several groups of tensors. These groups of tensors may be sent or transmitted to the parietal engine, and the parietal engine may take the groups of tensors to further divide them into several tensors. The parietal engine may send these tensors to the renderer engine for execution and may send a partial amount of tensors to the occipital engine. The occipital engine may accumulate the partial amount of tensors and may execute them. The occipital engine may send the output feature as the final tensor to the temporal engine. The temporal engine may compress the final tensor before storing or saving it to the memory.

Abstract: A data reuse method based on a convolutional neural network accelerator includes a tile scanning module receiving command information of a command module, the command information comprising a size of a CNN job to be divided into tile blocks; a tile scanning module according to a tile. The size of the tile generates the coordinates of the tile block and sends it to the memory request module; the memory request module generates a memory read request and sends the memory read request to the memory module; the memory module sequentially returns the tile block data to the input activation In the weight buffer unit, the input activation weight buffer unit saves the received tile block data to implement data reuse and transmits the received tile block data to the calculation processing unit PE.
