    摘要: A computing system includes a memory bus, a main memory (12), an I/O adapter (13) and a processor (10,11). The main memory (12), the I/O adapter (13) and the processor (10,11) are connected to the bus. The I/O adapter (13) includes a translation map (19). The translation map (19) maps I/O page numbers to memory address page numbers. The translation map (19) includes coherence indices. The processor (10,11) includes a cache (17,18) and an instruction execution means. The instruction execution means generates coherence indices to be stored in the translation map (19). The instruction execution means performs in hardware (36) a hash operation to generate the coherence indices.
