摘要: Cross-bar segment routing and access table address remapping functions are combined within a cross-bar of a system-on-a-chip. In this manner, address remapping may occur prior to segment routing. One or more access table caching registers may be included for each master port. The caching registers may allow for a rapid lookup of one or more access table entries associated with each master, as well as allow for the simultaneous lookup by multiple masters without adding ports to the access table. A segment identifier may be stored in the caching registers to indicate how to route a matching request to the appropriate slave segment.
