  • Patent number: 4313160
    Abstract: An improved distributed input/output system is disclosed for controlling numerous high speed peripheral devices (both low speed, medium speed, and high speed) and the transfer of data signals, status signals, and control signals between those devices and a general purpose digital computer. The control system described includes a direct-memory-access multiplexer which can accommodate a plurality of low or medium-speed input/output services and also high-speed input/output devices under the control of separate programmable microcoded peripheral-unit controllers. The direct-memory-access multiplexer of this invention is fully compatible with controllers that can also be used with an indirect-memory access multiplexer. Each controller, being an element of a distributed system, is adapted to be located at an individual peripheral device and each is connected to the multiplexer by an identical ribbon cable.

  • Patent number: 4261034
    Abstract: A special broadcast communication link is provided between a central processing unit and plural computer peripheral devices, the communication link being in addition to normal data and addressing communication lines, and providing a distributed control channel which is used to inhibit selected classes of interrupt signals from controllers associated with the peripheral devices in accordance with an interrupt classification system. This communication channel permits the central processing unit to issue a data command which selectively inhibits the peripheral devices from issuing selected classes of interrupt signals.

  • Patent number: 4245300
    Abstract: The input/output system for a computer of this invention permits a peripheral device and its associated peripheral processor to be connected either (a) directly to the central processor unit of the computer, or (b) to a remote hardware peripheral control device which permits the central processor unit to directly control the peripheral processor, or (c) to a remote input/output controller which controls the peripheral processor independently of the central processor unit of the computer. The input/output system of this invention permits the use of the same software set stored in memory to control the input/output operations of a selected peripheral device regardless of where the peripheral device is connected.

  • Patent number: 4124889
    Abstract: A distributed input/output system is disclosed for controlling numerous peripheral devices and the transfer of data signals and control signals between those devices and a general purpose digital computer. The control system described includes a multiplexer which can accommodate as many as eight input/output devices under the control of separate programmable microcoded peripheral-unit controllers. Each controller is adapted to be located at or on an individual peripheral device and each is connected to the multiplexer by an identical ribbon cable that is employed to carry both signals and power. Each controller employs a substantially identical microengine, that is, a microcoded processor, currently of five integrated circuit chips. The peripheral-unit controllers may be configured somewhat differently depending upon whether the peripheral device utilizes data signals in parallel or in series.
