Sending messages in a network-on-chip and providing a low power state for processing cores

Abstract

Subject matter disclosed herein relates to arrangements and techniques for sending messages directly among processing cores and directly among co-processors over a network-on-chip (NoC). More particularly, the present disclosure provides an Application Specific Integrated Circuit (ASIC) that includes processing cores coupled together with a NoC. Each processing core and co-processor includes two corresponding buffers. A first buffer is for sending messages and a second buffer is for receiving messages. Messages are sent from a processing core directly to another processing core through the NoC. Messages are also sent from a co-processor directly to another co-processor through the NoC.
