Abstract
A method and apparatus for arbitrating access requests to a memory is accomplished which allows for the serialization of the memory access requests, when a memory access collision is detected. A memory access collision is detected when contemporaneous accesses to an identical memory block of the memory occur. Processing begins when a plurality of operations are received via a plurality of parallel pipelines, wherein at least some of the plurality of operations require memory access. The plurality of parallel pipelines are then monitored for memory access collisions. At least some of the plurality of pipelines are then serialized when a memory access collision is detected to ensure proper processing order of the plurality of operations involved in the memory access collision.
