Coherency for Multiprocessor Virtual Address Caches

  title={Coherency for Multiprocessor Virtual Address Caches},
  author={James R. Goodman},
A multiprocessor cache memory system is described that supplies data to the processor based on virtual addresses, but maintains consistency in the main memory, both across caches and across virtual address spaces. Pages in the same or different address spaces may be mapped to share a single physical page. The same hardware is used for maintaining consistency both among caches and among virtual addresses. Three different notions of a cache "block" are defined: (1) the unit for transferring data… CONTINUE READING
