ABSTRACT:
A computing system includes a memory bus, a main memory, an I/O adapter and a processor. The main memory, the I/O adapter and the processor are connected to the bus. The I/O adapter includes a translation map. The translation map maps I/O page numbers to memory address page numbers. The translation map includes coherence indices. The processor includes a cache and an instruction execution means. The instruction execution means generates coherence indices to be stored in the translation map. The instruction execution means performs in hardware a hash operation to generate the coherence indices.
