Abstract

A combining switch that reduces memory accesses, synchronizes parallel processors and is easy to implement, is achieved by configuring a plurality of parallel processing nodes in a ring arrangement and by implementing a synchronizing instruction for the switch that facilitates, rather than inhibits, parallel processing. According to the preferred embodiment of the invention the ring is a token ring and the synchronizing instruction is a Fetch-and-Add instruction.
