Abstract
Optimizing transaction traffic on a System on a Chip (SoC) by using procedures such as expanding transactions and consolidating responses at nodes of an interconnect fabric for broadcasts, multi-casts, any-casts, source based routing type transactions, intra-streaming two or more transactions over a stream defined by a paired virtual channel-transaction class, trunking physical resources sharing common logical identifier, and using hashing to select among multiple physical resources sharing a common logical identifier.
Claims22
A System on Chip (SoC), comprising:
- an interconnect fabric;
- and
- a plurality of IP agents interconnected by the interconnect fabric, the plurality IP agents configured to be sources and destinations of transactional traffic transmitted over the interconnect fabric between the IP agents;
- wherein a first IP agent is configured to generate and send a Source Based Routing (SBR) transaction that specifies one or more destination IP agents among the plurality of IP agents on the SoC,
- wherein the interconnect fabric is configured to make a routing decision on how to route and deliver the SBR transaction over the interconnect fabric to the one or more destination IP agents among the plurality of IP agents on the SoC.
