Abstract: The present disclosure discloses example operation accelerators and compression methods. One example operation accelerator performs operations, including storing, in a first buffer, first input data. In a second buffer, weight data can be stored. A computation result is obtained by performing matrix multiplication on the first input data and the weight data by an operation circuit connected to the input buffer and the weight buffer. The computation result is compressed by a compression module to obtain compressed data. The compressed data can be stored into a memory outside the operation accelerator by a direct memory access controller (DMAC) connected to the compression module.
