Modular interconnection architecture for expandable multiprocessor engine, implementing a virtual bus hierarchy comprising a plurality of levels, each level comprising the same basic element

摘要

The architecture has a first level of interconnection (MI) with connection agents linking multiprocessor modules and managing transactions between them, and a second level of interconnection (SI) with external connection nodes (NCEj) connecting nodes and managing transactions between them. Each external connection node has two identical agents (NCS'j, NCSj), connected back-to-back.
