Abstract: A non-keyboard computer peripheral device represents itself to a host computer as having a keyboard function in addition to representing its actual function. Keyboard status signals are generated by the host computer in response to a user pressing different keys on an actual keyboard. The peripheral device uses the keyboard status signals to identify different peripheral device operations selected by the user. In one example, a radio receiving device represents itself to the host computer as including the keyboard function. Pressing a button on the receiving device causes the receiving device to send a sequence of keystroke commands to the host computer that cause the host computer to initiate software applications and to display operating instructions to a user. A series of further binding operations are then executed in accordance with the displayed operating instructions.

Abstract: An X display may be dynamically rerouted to a different graphics terminal, or to several graphics terminals, without disrupting X clients. The corresponding X server architecture includes a static, protocol router part which acts as an endpoint for client connections and which routes X protocol to one or more X server displays, and a dynamic X display part which maintains the state and contents of the display. An X display may maintain its state and display contents entirely in memory without any need for physical display or input devices, in which case it is termed a “headless X display” and provides a virtual X server display that appears to the host as if it were a user-interactive display. The architecture allows for any number of X displays to be attached to the protocol router for multi-user, fault tolerant or suspend/resume functionality.

Abstract: An access monitoring section (11) obtains access information including an address conforming to an address stored in a monitoring address setting section (10) from an access signal output from a CPU (1) to a peripheral device (3). An access judging section (13) compares the access information received from the access monitoring section (11) and the last access information stored in an access storing section (12), and stores the obtained access information in the access storing section (12) and requests the transmission of an exception generation notification to an exception generating section (14) when the received access information is different from the last access information while excluding the last access information stored in the access storing section (12) from access information to be compared when the received access information is the same as the last access information. By this construction, throughput can be reduced at the time of emulation and the peripheral device can be efficiently emulated.

Abstract: Emulating a NIC for packet transmission on hardware RSS unaware NICs in a multi-core system enables each of a plurality of slave packet engines to emulate a NIC for packet transmissions locally even though the actual NIC transmissions from the queue are handled by a master packet engine only. Each slave packet engine treats a local software-implemented transmission queue as a device queue and uses the local queue to keep track of status of data from the packet engine in the device output queue, handled by the master packet engine on behalf of the slave packet engines. As the master packet engine transmits the data from the queue and the status of the queue changes, the master packet engine and the slave packet engines may use pointers to keep track of which data packets are transmitted, which data packets are drained and which data packets are still in the queue.
