ABSTRACT:
A direct mapped cache with cache locking according to one embodiment of the present invention includes a physical address latch and a multiplexing means. The multiplexing means receives the physical address from the physical address latch and exchanges a physical address tag bit with a physical address index bit to generate a cache tag address and a cache index address to divide the cache into two halves, each half servicing a contiguous address range of main memory.
