Patent number: 5535333Abstract: A system and method for controlling a communications adapter interface such that supplemental data can be interleaved with data being transferred. The interleaving is performed in a manner such that the supplemental data is transparent to the data mover portion of the communications adapter. The supplemental data can be transferred in either read or write cycles that are interleaved at the beginning, in the middle, or at the end of data bursts or block data transfers. As a result of the interleaving, the slave interface bus is more fully utilized because arbitration and bus ownership changes do not create unused cycles. The interleaving is accomplished by temporarily halting an existing transfer of data and transferring the requested supplemental data while the data transfer is halted. After the supplemental data is transferred, the transfer of the balance of the data block is then allowed to continue.Type: GrantFiled: March 30, 1993Date of Patent: July 9, 1996Assignee: International Business Machines CorporationInventors: James J. Allen, Jr., Ronald J. Cooper, Douglas H. Cox, William L. McNeil, Herbert Rivera-Sanchez, Terri L. Tomlinson

Patent number: 5286438Abstract: The method of fabricating a complex part made of composite material and having a plurality of panels oriented in diverse angular relationship, and utilizing a plurality of conformable cauls upon which the composite material is individually laid up and which cauls cooperate to form one of the molds used in the co-curing of the individually laid-up composite materials.Type: GrantFiled: June 12, 1992Date of Patent: February 15, 1994Assignee: United Technologies CorporationInventors: Alexander C. Dublinski, Ronald J. Cooper, Edward J. Fabian, Gary J. Jacaruso, Philip J. Ramey, Darryl M. Toni, Matthew T. Turner

Patent number: 4870566Abstract: A communications concentrator and message multiplexer featuring direct access from the communications adapters to main memory via direct memory access means which eliminates the usual scanner or polling facility in a concentrator or multiplexer is described. A control microprocessor manages the allocation of memory, the conversion of message protocols and the servicing of interrupts to a plurality of port interface adapter microprocessors. The interface adapter microprocessors directly set up and control the DMA operation instead of having the DMA operation controlled by the control processor. One of the port adapters serves as a service adapter over a dedicated interface allowing a remote disgnostician access to internal registers in the control processor system, access to a dedicated read only storage for servicing, and logical interface to the main control processor for the purpose of entering instructions and directing functional operations to test each component of the system.Type: GrantFiled: August 27, 1984Date of Patent: September 26, 1989Assignee: International Business Machines Corp.Inventors: Ronald J. Cooper, Mario A. Marsico, Richard C. Matlack, Jr., John C. Pescatore, Robert L. Smith, Jr.

Patent number: 4837677Abstract: 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.Type: GrantFiled: June 14, 1985Date of Patent: June 6, 1989Assignee: International Business Machines CorporationInventors: Gilbert S. Burrus, Jr., Ronald J. Cooper, Michael R. Marr, Mario A. Marsico, John C. Pescatore, Paul D. Sullivan

Patent number: 4751634Abstract: 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.Type: GrantFiled: June 14, 1985Date of Patent: June 14, 1988Assignee: International Business Machines CorporationInventors: Gilbert S. Burrus, Jr., Ronald J. Cooper, Michael R. Marr, Mario A. Marsico, John C. Pescatore, Paul D. Sullivan

Patent number: 4716523Abstract: Both DMA access and character interrupt driven access modes of service are provided to multiple communication ports by an integrated arbitration DMA/interrupt controller utilizing its own resident randomly accessible memory. Pipelined logic control architecture for handling service mode adaptations for each individual port and for managing memory accesses to main system memory enables the use of the random access memory with its inherent time delays in a manner that virtually eliminates the effect of any time delay in overall memory access throughput.Type: GrantFiled: June 14, 1985Date of Patent: December 29, 1987Assignee: International Business Machines CorporationInventors: Gilbert S. Burrus, Jr., Ronald J. Cooper, Michael R. Marr, John C. Pescatore, Mario A. Marsico

Patent number: 4648029Abstract: 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.Type: GrantFiled: August 27, 1984Date of Patent: March 3, 1987Assignee: International Business Machines CorporationInventors: Ronald J. Cooper, Mario A. Marsico, John C. Pescatore, Paul D. Sullivan

Patent number: 4627054Abstract: A multiprocessor array is described in which a central controlling microprocessor interfaces over commonly connected address and data busses to a plurality of peripheral microprocessors. A memory mapped I/O interface controls access to and from the busses for mutual receipt and exchange of signals between the processors and mutual exchange and receipt of data among the processors. The individual processors are selectively isolatable by a plurality of three state switch means connected between each processor and the interconnecting data and address busses. Error detection and control logic is connected via control lines to the individual processors and responsive to an error indication thereof, activates a multipoint error signal to all said microprocessors over a control line, which signal is interpreted by the processor then controlling said busses as a signal to deactivate its operation and as a signal at said control microprocessor to invoke an interrupt for analyzing the causes of said error.Type: GrantFiled: August 27, 1984Date of Patent: December 2, 1986Assignee: International Business Machines CorporationInventors: Ronald J. Cooper, Mario A. Marsico, John C. Pescatore
