Abstract
A proximity interconnect module includes a plurality of processors operatively connected to a plurality of off-chip cache memories by proximity communication. Due to the high bandwidth capability of proximity interconnect, when an off-chip cache memory is searched for requested data, either the requested data is at the same time searched for in on-chip cache memories of the proximity interconnect module or the requested data is at the same time retrieved from main memory. This reduces latency by reducing serial operations.
