ABSTRACT:
The processor's interrupt stack memory and cache memory share a common data memory and are accessed using virtual addresses. A separate address translation buffer (ATB) is used for both the interrupt stack memory and cache memory to perform the virtual address to real address translations which are required to access the common data memory. The cache ATB and a cache controller provide the addressing to access cache data words in the common memory; whereas the interrupt stack ATB alone provides the addressing necessary to access the interrupt stack data words in the common memory.
