    摘要: A multi-port communications controller and variable protocol adapter is described. The adapter utilizes a user programmable pluggable programming cartridge for defining individual communications port data service characteristics. The port data service characteristics are interpreted by a microprocessor which manages the interchange from port to port and to or from memory or a host system. Direct memory access or interrupt driven memory access modes of operation are individually selectable for each individual in bound and out bound communications channel. The communications protocols employed at each port may be of any standard type with the microprocessor in the adapter making the appropriate conversion. Communication speeds can be automatically recognized and matched for each port also. An arbitration processor for both DMA and interrupt driven data transfer services is included as the heart of the communications adapter design to provide the capability of individualized control over each in bound and out bound channel's mode of data transfer service for the optimum mode of operation for each port and type of data service required.

    摘要: Bus interconnection between the system busses of a multi-port communications controller and the busses of one or more multi-port adapters is facilitated with a new architecture for providing an interconnection controller. A programmably adjustable adapter and port interface controller is combined via a scannerless communications controller with a bus interconnection control logic that handles both DMA and interrupt mode data transfers for a large number of channels. The invention provides an improved apparatus and method for transferring data to or from numerous communication channel devices within a processor based communications system in such a manner that the optimum mode of data transfer may be individually programmed for each channel as system environment conditions demand.

    摘要: In an arbitration apparatus and technique, the request lines from a plurality of potential requestors serve both as interrupt and DMA bus request signal lines to an arbitration device. The arbitration device selects among contending requestors on a priority basis and generates a grant signal interpreted by the requesting devices either as an interrupt grant or a bus grant depending upon whether or not an interrupt acknowledge signal is received. This effectively multiplexes the grant request lines from a plurality of requestors to greatly reduce interconnection complexity and cost. A single interrupt grant/bus grant multi-wire signal cable connects from the arbitration device to the individual requestors. A grant will appear on a single line thereof connected to an individual requestor that has been granted either an interrupt or access to the bus. Interrupt requests from the requestors are ORed together and simultaneously presented to a central controlling microprocessor. The arbitration device determines which requestor will be granted access and, under control of the central control microprocessor, the arbitrator gates an interrupt grant or a DMA grant signal to the device selected by the arbitration mechanism. The dual usage of the grant and request lines by the arbitration device represents a multiplexing feature to further reduce interconnections.

    摘要: A wood burning stove is disclosed which includes a stove housing that defines an upper zone comprising storage and exhaust chambers, and a lower zone for accommodating a wood burning fire. The exhaust and storage chambers are separated by a divider, both chambers having bottom openings that communicate directly with the top of the lower fire zone. Covering one opening in the housing and providing access to the fire zone is a fire door while another opening provides access at the top of the storage chamber and is covered by a wood fill door. The exhaust chamber communicates with and discharges smoke into a stovepipe or flue retaining chimney. A supply of logs is loaded into the storage chamber through its fill door. These feed automatically and sequentially by gravity from the storage chamber bottom into the fire zone for consumption by a fire burning therein. The frequency of wood loading operations is reduced in that a suitable supply of logs for burning and maintaining a continuous fire over a long period of time is provided in one loading operation.
