STREAMING BRIDGE DESIGN WITH HOST INTERFACES AND NETWORK ON CHIP (NoC) LAYERS

摘要

Systems and methods described herein are directed to streaming bridge design implementations that help interconnect and transfer transaction packets between multiple source and destination host interfaces through a Network on Chip (NoC) interconnect, which includes a plurality of NoC router layers and virtual channels (VCs) connecting the router layers. Implementations are configured to support a variety of different traffic profiles, each having a different set of traffic flows. Streaming bridge design implementation can divide streaming bridge into a streaming TX bridge and a streaming RX bridge, wherein TX bridge is operatively coupled with host TX interfaces and RX bridge is operatively coupled with host RX interfaces, and where TX bridge forwards transaction packets from host TX interfaces to different router layers/VCs of NoC, and RX bridge, on the other hand, receives packets from NoC router layers/VCs and transmits the packets to host RX interfaces based on Quality of Service.

1. A method for transacting data from a source host to a destination host, the method comprising:
receiving, at a streaming TX bridge, one or more transaction packets and one or more traffic profiles from a plurality of source host interfaces; processing the one or more transaction packets at the streaming TX bridge based on the one or more traffic profiles to identify routing details for the one or more transaction packets; transmitting the one or more transaction packets based on the routing details; and receiving, at a streaming RX bridge, the one or more transaction packets for onward transmission to a plurality of destination host interfaces of the destination host.
