Method and Related Apparatus for Internal Data Accessing of Computer System

Abstract

Method and related apparatus for internal data accessing of a computer system. In a computer system, a peripheral can issue accessing requests for system memory space with or without snooping the central processing unit (CPU). While serving a peripheral of single virtual channel utilizing a chipset supporting multiple virtual channels, the present invention assigns accessing requests to different processing queues according to their snooping/non-snooping attributes, such that reading/non-snooping requests are directly routed to system memory. Also responses from system memory and CPU will be buffered in the chipset respectively utilizing buffer resources of different virtual channels. By applying accessing routing dispatch, data accessing efficiency efficient will be increased.
