  • Multiple function array based application specific integrated circuit
    Patent number: 6157051
    Abstract: An array based application specific integrated circuit includes four application specific integrated circuits on one die. Each of the four application specific integrated circuits functions in a certain mode. Only one of the four application specific integrated circuits is activated at any time. Activation of a mode is determined by the configuration of mode selection circuitry of the array based application specific integrated circuit. The four modes are not interrelated, and the four application specific integrated circuits do not share transistors in the array based application specific integrated circuit. The four application specific integrated circuits may share input/output pins of the array based application specific integrated circuit.

  • Microprogrammable processor capable of accessing unused portions of control store as fast data memory
    Patent number: 5664169
    Abstract: A microprogrammable processor is capable of accessing unused portions of a control store as fast data memory. The microprogrammable processor includes a microsequencer that accesses microinstructions from either an internal control store or an external control store. These microinstructions control the operation of the microprogrammable processor. When the microsequencer accesses instructions from an internal control store, the microprogrammable processor is operable to access external control store as fast data memory.
