Abstract: A method of parallel execution of a first and a second instruction in an in-order processor. Embodiments of the invention enable parallel execution of memory instructions that are stalled by cache memory misses. The in-order processor processes cache memory misses of instructions in parallel by overlapping the first cache memory miss with cache memory misses that occur after the first cache memory miss. Memory-level parallelism in the in-order processor can be increased when more parallel and outstanding cache memory misses are generated.
