20090210580 | EARLY TERMINATION OF AN I/O OPERATION IN AN I/O PROCESSING SYSTEM - A computer program product, apparatus, and method for handling early termination of an I/O operation at a channel subsystem in an I/O processing system are provided. The computer program product includes a tangible storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method. The method includes receiving a request to terminate an I/O operation, and transmitting an abort command to a control unit in communication with the channel subsystem in response to receiving the request to terminate the I/O operation. The method also includes transmitting a purge path command to purge a path associated with the I/O operation, where the purge path command includes an error code identifying the request to terminate the I/O operation. | 08-20-2009 |

20100262729 | CONFIGURABLE BUS TERMINATION FOR MULTI-CORE/MULTI-PACKAGE PROCESSOR CONFIGURATIONS - A multi-core/multi-package bus termination apparatus includes a configuration array and a plurality of drivers. The configuration array generates location/protocol signals that each direct one of the plurality of drivers on the bus to employ location-based bus termination or protocol-based bus termination. The plurality of drivers is coupled to the plurality of location/protocol signals, a plurality of location signals, a bus ownership signal, and a multi-package signal. Each of the plurality of drivers controls how one of a plurality of nodes is driven responsive to a first state of one of the plurality of location/protocol signals. Each has configurable multi-core/multi-package logic controls pull-up logic, first pull-down logic, and second pull-down logic according to location-based termination rules if the first state indicates the location-based termination, and controls the pull-up logic, the first pull-down logic, and the second pull-down logic according to protocol-based termination rules if the first state indicates the protocol-based termination. | 10-14-2010 |
20120110219 | DATA PROCESSING CIRCUIT AND DATA PROCESSING APPARATUS - According to one embodiment, a data processing circuit included in a data processing apparatus together with plural peripheral circuits including a peripheral circuit configured to output first data includes a processing unit and a stop unit. The processing unit subjects the first data to data processing according to a specified processing algorithm to obtain second data. The stop unit stops the output of the second data to the outside of the data processing circuit in a stop period excluding a period from the time when the plural peripheral circuits finish starting in specified start order until the time when a specified time elapses after the plural peripheral circuits finish stopping in specified stop order. | 05-03-2012 |
20120124252 | DATA TRANSFERRING APPARATUS AND CONTROL METHOD THEREOF - A data transferring apparatus, that is capable of connecting to at least one device and that transfers a request from a host to the device, obtains, in response to receiving a suspend request for suspending at least one of the devices from the host, configuration data of the target device (or port) for suspension indicated by the suspend request from the device, and saves the obtained configuration data. During resume, the saved configuration data is set in the device (or the port). | 05-17-2012 |
20120233361 | HOST DEVICE SUSPENDING COMMUNICATION LINK TO CLIENT DEVICE BASED ON CLIENT DEVICE NOTIFICATION - A communication link between a host device and a client device can be suspended based on a suspend request or notification provided by the client device. The suspend request can be transmitted by a client device to a host device if the client device determines that suspension is appropriate, and can be sent in response to receiving a polling request from the host device. After receiving a suspend request, the host device can initiate an operation to suspend the communication link between the devices. | 09-13-2012 |
20130124761 | METHOD AND APPARATUS FOR MAINTAINING NETWORK COMMUNICATION DURING MAINTENANCE - A communication method for use by an input/output (I/O) scanner coupled to a programmable logic controller (PLC) includes coupling at least one I/O module to a backplane, and coupling a maintenance module to the backplane. The communication method also includes selectively enabling and disabling communication between the backplane and the at least one I/O module by actuating a switch in the maintenance module such that network communication is maintained by a network interface regardless of whether communication between the backplane and the at least one I/O module is enabled. | 05-16-2013 |
20130262715 | ELECTRONIC APPARATUS AND HOST DETERMINATION METHOD - An electronic apparatus includes a plurality of interfaces and a host determination controller. To the plurality of interfaces, a plurality of host candidate devices are individually connected. The plurality of host candidate devices are each capable of serving as a host device that performs control. The host determination controller is configured to determine, based on a reception signal received from one of the plurality of host candidate devices, a predetermined host candidate device serving as a transmission source of the reception signal to be a host device, and to control a disconnection and a connection of at least one of the plurality of interfaces, the at least one of the plurality of interfaces corresponding to at least one of the other host candidate devices. | 10-03-2013 |
