Store queue for a tightly coupled multiple processor configuration with two-level cache buffer storage

Abstract From the Canadian patent

A multiprocessor system includes a system of store queues and write buffers in a hierarchical first level and second level memory system including a first level store queue for storing instructions and/or data from a processor of the multiprocessor system prior to storage in a first level of cache a, second level store queue for storing the instructions and/or data from the first level store queue and a plurality of write buffers for storing the instructions and/or data from the second level store queue prior to storage in a second level of cache. The multiprocessor system includes hierarchical levels of caches, including a first level of cache associated with each processor a, single …
