  • Cache memory consistency control with explicit software instructions
    Patent number: 4713755
    Abstract: Memory integrity is maintained in a system with a hierarchical memory using a set of explicit cache control instructions. The caches in the system have two status flags, a valid bit and a dirty bit, with each block of information stored. The operating system executes selected cache control instructions to ensure memory integrity whenever there is a possibility that integrity could be compromised.
