ABSTRACT:
A data cache unit associated with a processor, the data cache unit including a multi-ported non-blocking cache receiving a data access request from a lower level device in the processor. A memory scheduling window includes at least one row of entries, wherein each entry includes an address field holding an address of the access request. A conflict map field within at least some of the entries is coupled to a conflict checking unit. The conflict checking unit responds to the address fields by setting bits in the conflict map fields to indicate intra-row conflicts between entries. A picker coupled to the memory scheduling window responds to the conflict map fields so as to identify groups of non-conflicting entries to launch in parallel at the multi-ported non-blocking cache.
