Abstract

A cache includes a data memory, a tag memory, and a cache controller. The data memory includes a stack area storing, in a stack structure, data used by an external processor in a plurality of cache lines. The tag memory stores a tag entry including useless information indicating whether data stored in a corresponding cache line has been popped. The cache controller is configured to, when a pop request for data stored in the stack area is received, change the useless information of a cache line storing the data subject to the pop request, to a useless state.
