Simultaneous eviction and cleaning operations in a cache

Abstract

Embodiments provide a method comprising receiving, at a cache associated with a central processing unit that is disposed on an integrated circuit, a request to perform a cache operation on the cache; in response to receiving and processing the request, determining that first data cached in a first cache line of the cache is to be written to a memory that is coupled to the integrated circuit; identifying a second cache line in the cache, the second cache line being complimentary to the first cache line; transmitting a single memory instruction from the cache to the memory to write to the memory (i) the first data from the first cache line and (ii) second data from the second cache line; and invalidating the first data in the first cache line, without invalidating the second data in the second cache line.

Dependencies are inferred from the claim text.
