Abstract: A deep neural network hardware accelerator based on power exponent quantisation, relating to a deep neural network convolutional computing hardware acceleration processor structure, and relating to the technical fields of computing, calculating, and counting. The hardware accelerator comprises: an AXI-4 bus interface, an input cache area, an output cache area, a weighting cache area, a weighting index cache area, an encoding module, a configurable state controller module, and a PE array. The input cache area and the output cache area are designed as a line cache structure; an encoder encodes weightings according to an ordered quantisation set, the quantisation set storing the possible value of the absolute value of all of the weightings after quantisation. During the calculation of the accelerator, the PE unit reads data from the input cache area and the weighting index cache area to perform shift calculation, and sends the calculation result to the output cache area. The accelerator uses shift operations to replace floating point multiplication operations, reducing the requirements for computing resources, storage resources, and communication bandwidth, and thereby increasing the calculation efficiency of the accelerator.
