Cache operation method, cache, computing device and system

Abstract

Embodiments of the present disclosure provide a cache operation method, a cache, a computing device and a system, and relate to the technical field of chips. The cache operation method is applied to a cache, the cache comprising a shared cache and an atomic cache. The shared cache comprises a plurality of shared cache blocks for storing data corresponding to different types of cache operation requests. The atomic cache comprises a plurality of atomic data cache blocks for storing atomic data corresponding to atomic operation requests. The cache operation method comprises: determining, according to a cache operation request sent by a computing unit, a first cache block for storing target data from the plurality of shared cache blocks, the target data being data corresponding to the cache operation request; determining whether a second cache block corresponding to the first cache block exists in the plurality of atomic data cache blocks of the atomic cache, the second cache block storing part of the data of the first cache block; and if the second cache block exists in the atomic cache, performing the cache operation request at least according to the second cache block.
