NOC INTERFACE PROTOCOL ADAPTIVE TO VARIED HOST INTERFACE PROTOCOLS

摘要

Systems and methods described herein are directed to solutions for Network on Chip (NoC) interconnects that support a variety of different component protocols each having different sets of data and/or metadata even after the NoC is designed and finalized. Example implementations include, automatically changing format of packets received from an originating SoC component by an originating bridge based on a NoC interface protocol and then transmitting the packet across the NoC interconnect to a destination bridge. The format may again be changed based on the protocol of the destination SoC component. The proposed protocol can be configured to map various transactions presented to it, be they packets belonging to the physical, data link layer, network layer or transport layer. As part of the mapping process, virtual channels for latency or deadlock avoidance may be created and may be maintained for the entire life of the packet within the NoC.
