US 2013/0086296 A1 · Providing Multiple Decode Options For A System-On-Chip (SoC) Fabric

Abstract

In one embodiment, a system-on-chip (SoC) can be configured to receive a request from a master agent in a fabric coupled to the master agent, send a show command grant to the master agent responsive to selection of the request by the fabric, receive a command portion of a transaction corresponding to the request in the fabric and determine a target agent to receive the transaction based on the command portion, and thereafter send a transaction grant to the master agent for the transaction. Other embodiments are described and claimed.
