METHOD, APPARATUS AND COMPUTER PROGRAM FOR ROUTING DATA REQUEST IN SYSTEM-ON-CHIP

摘要

PROBLEM TO BE SOLVED: To improve system performance by making the routing of a data request within a system-on-chip (SOC) into a stream and minimizing hardware requisition. SOLUTION: Cross-bar segment routing and access table address remapping functions are combined within a cross-bar of a system-on-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, and 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. COPYRIGHT: (C)2010,JPO&INPIT
