HHMA: A Hierarchical Hybrid Memory Architecture Sharing Multi-Port Memory

Rational memory architecture plays more and more roles on improving parallel communication performance of multi processor system. A hierarchical hybrid memory architecture constructed by sharing multi-port memory, HHMA, is proposed in this article. In HHMA, multi-port memories are adopted as the shared memory for processor nodes in different groups. The high parallelism of multi-port memory assures processor nodes to access memory at high parallel degree. Experiments showed that the node parallel degree when accessing shared memory in HHMA is higher than 90%.
