Abstract: Methods, apparatus, systems and articles of manufacture to facilitate atomic compare and swap in cache for a coherent level 1 data cache system are disclosed. An example system includes a cache storage; a cache controller coupled to the cache storage wherein the cache controller is operable to: receive a memory operation that specifies a key, a memory address, and a first set of data; retrieve a second set of data corresponding to the memory address; compare the second set of data to the key; based on the second set of data corresponding to the key, cause the first set of data to be stored at the memory address; and based on the second set of data not corresponding to the key, complete the memory operation without causing the first set of data to be stored at the memory address.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to forward and invalidate inflight data in a store queue. An example apparatus includes a cache storage, a cache controller coupled to the cache storage and operable to receive a first memory operation, determine that the first memory operation corresponds to a read miss in the cache storage, determine a victim address in the cache storage to evict in response to the read miss, issue a read-invalidate command that specifies the victim address, compare the victim address to a set of addresses associated with a set of memory operations being processed by the cache controller, and in response to the victim address matching a first address of the set of addresses corresponding to a second memory operation of the set of memory operations, provide data associated with the second memory operation.
