Explicit multi-core Cache consistency active management method facing flow application

Disclosed is an explicit multi-core Cache consistency active management method facing flow application. The method comprises the steps that private data Cache set an optional total state descriptor and a shared data function digit of an identification Cache to the read-write state of shared data; the total state descriptor is used for identifying the operational state of the whole private data Cache to the shared data currently, Y groups are configured according to the number requirement for simultaneous locking of the Cache, the feature information of each locking area is stored in each group, and a shared address section or locking sign information can be achieved; the shared data function digit is a two-dimensional array register, the width is N, and the depth is M; the N is used for distinguishing N different locking shared data areas corresponding to lines or blocks of the Cache, and the M is the same as the number of the lines or the blocks of the private data Cache to identify the corresponding lines or the blocks of the Cache to determine whether the shared data need to be read and written or not. The explicit multi-core Cache consistency active management method facing the flow application has the advantages of being simple in principle, convenient to operate, small in price for hardware implementation, good in expandability, strong in configurability, capable of improving system efficiency and the like.
