  • Patent number: 6026481
    Abstract: A chip includes a programmable logic device and a microprocessor, wherein at least one of the associated registers of the microprocessor is distributed in the programmable logic device. The distributed register is coupled to both the microprocessor and the programmable logic device. In this manner, the microprocessor has the ability to access the register and place a value into the programmable logic device all in one clock cycle. Additionally, the logic functions in the programmable logic device are also advantageously available to the microprocessor.

  • Patent number: 4438492
    Abstract: A microprogram controller, in a microcomputer system used as an address sequencer intended for controlling the sequence of execution of microinstructions in a microprogram memory, is presented. The microprogram controller includes architecture that provides the capability to asynchronously receive indications of an event, break from the microinstruction sequence in response, branch to control of subroutine consisting of a predetermined microinstruction sequence directed to responding to the event, and returning to the interrupted sequence upon completion of the subroutine.
