Abstract

The Semantic Network Array Processor (SNAP) is a parallel architecture for knowledgerepresentation and reasoning that uses the marker-propagation paradigm. The primaryapplication areas of SNAP are natural language understanding and speech processing. Afirst-generation SNAP-1 system has been designed and constructed using an array of 144digital signal processors organized as 32 multiprocessing clusters with dedicatedcommunication units, a tiered synchronization scheme, and multiported memory network.Issues in the design, performance, and scalability of a marker-propagation architectureare addressed.
