  • Patent number: 5649155
    Abstract: In a cache memory system, continuation registers are provided to abbreviated address data identifying the line position in the cache memory from which data is fetched. When data is fetched from a line in said cache memory, the bin number and line position identification of the line in the cache memory are saved in a continuation register. Then, subsequently, when data is fetched from the same line, it is fetched by a continuation request wherein the data saved in the continuation register is used to access the cache memory. The continuation registers provide the abbreviated address data for comparison in both PSC (program store compare) and OSC (operand store compare).

  • Patent number: 5417235
    Abstract: Micromachined microvalves are held both open and closed electrostatically to maintain uniform gas microflow and improve closure characteristics. A microflow controller containing such a valve is combined with a predetermined restricted flow path. Multiple valve/restrictive flow path combinations are integrated on a binary flow path basis. Single and/or multiple valve actuation provides precise but variable flow control. Temperature and pressure sensors can be integrally included. Various valve and controller configurations, and methods of controlling them and forming them, are disclosed.
