ABSTRACT:
In one of the many embodiments disclosed herein, a method for dispatching read and write requests to a memory is disclosed which includes queuing at least one write request in a write queue and queuing an incoming read request in a read queue. The method also includes comparing the read request with at least one write request in the write queue to detect a matching write request, and if there is a matching write request, storing a write queue index of the matching write request as a first entry in an ordering queue. The method further includes dispatching the at least one write request to the memory in response to the first ordering queue entry.
