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.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to reduce read-modify-write cycles for non-aligned writes. An example apparatus includes a memory that includes a plurality of memory banks, an interface configured to be coupled to a central processing unit, the interface to obtain a write operation from the central processing unit, wherein the write operation is to write a subset of the plurality of memory banks, and bank processing logic coupled to the interface and to the memory, the bank processing logic to determine the subset of the plurality of memory banks to write based on the write operation, and determine whether to cause a read operation to be performed in response to the write operation based on whether a number of addresses in the subset of the plurality of memory banks to write satisfies a threshold.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed facilitate read-modify-write support in a coherent victim cache with parallel data paths. An example apparatus includes a random-access memory configured to be coupled to a central processing unit via a first interface and a second interface, the random-access memory configured to obtain a read request indicating a first address to read via a snoop interface, an address encoder coupled to the random-access memory, the address encoder to, when the random-access memory indicates a hit of the read request, generate a second address corresponding to a victim cache based on the first address, and a multiplexer coupled to the victim cache to transmit a response including data obtained from the second address of the victim cache.
