Abstract
A computer system has a central processing unit, a north bridge electrically connected to the central processing unit, memory electrically connected to the north bridge, a south bridge electrically connected to the north bridge, and a peripheral device electrically connected to the south bridge. The south bridge includes a register for storings a plurality of pre-fetched read data to provide the pre-fetched read data to the peripheral device. The north bridge has an address queue module for storing an address of the pre-fetched read data, and a snooping module for checking whether a data value corresponding to the address is updated by the CPU. The north bridge assists the south bridge in obtaining and maintaining the pre-fetched read data for high efficiency and accuracy of read caching of the south bridge.
