  • Memory access control circuit
    Patent number: 4549273
    Abstract: A circuit which controls access of host and remote processors to a single memory. A first flip-flop indicates acceptance or refusal of the processor's memory access requests. A second flip-flop provides a wait signal to the host processor when the remote processor is accessing the memory. A gating circuit causes the first flip-flop to accept the remote processor's access request when both the host and remote processors request memory access at the same time.

  • Computer channel access circuit for multiple input-output devices
    Patent number: 4314164
    Abstract: An access circuit for use in a computer input-output channel. Retriggerable mono-stable multivibrators are used to provide access timing periods during which an input-output device can access a computer channel to the exclusion of other input-output devices.

  • Noise eliminator circuit
    Patent number: 4282488
    Abstract: A noise eliminator circuit for use in a decoding circuit. A flip-flop is used to delay a first pulse train by the pulse width of a second pulse train so that pulse level transitions of the first pulse train occur non-coincident with the pulse level transitions of a synchronously generated third pulse train.
