Abstract
A method and apparatus for efficiently controlling the access to a cached shared resource such as dynamic random access memory (DRAM). The access is effected in a pseudo-concurrent manner by two devices such as a central processing unit (CPU) and a bus master agent. While one device accesses data stored in the DRAM, the other device accesses a copy of the DRAM data which is stored in the cache of the shared resource.
