Abstract: In a transmitting terminal, a first displaying section displays, synchronously with a receiving terminal, a portion of content that has been transmitted to the receiving terminal. A second displaying section displays a portion of the content that has yet to be transmitted to the receiving terminal. A saving flag setting section sets a saving flag, the saving flag specifying whether to permit or prohibit the receiving terminal to save the content after the receiving terminal receives and displays the content. An adder adds the saving flag to the content; and a transmitter transmits the content to the receiving terminal with the saving flag.

Abstract: An electronic system comprises a defined number N of functional modules, including a defined number P of initiator modules and a defined number Q of target modules, where N, P and Q are integer numbers such that 2?P?N and 1?Q?N. In the event of a plurality of conflicting requests to access a common resource originating from a plurality of respective initiator modules, an arbitration unit grants an exclusive right of access to the resource to a defined one of these initiator modules. The arbitration unit is constructed either to apply a standard arbitration mechanism to these respective initiators, or to apply as a priority a specific arbitration mechanism only to the members of a subset of these initiator modules, for each of which it receives a linked privileged access signal.
Abstract: A system and method is disclosed for the handling of interrupts by the disabled logical processors of an information handling system or computer system. An interrupt service routine is written to the read-only portion of system memory. Upon receipt of an interrupt, each disabled logical processor branches to the hard coded interrupt service routine. The interrupt service routine can be written to read only memory because the context, current instruction, and return state of the disabled logical processor are known, and the disabled logical processor will not need to write to system memory during the execution of the interrupt service routine. Following the handling of the interrupt by another logical processor of the computer system, each disabled logical processor returns to the halt state.

Abstract: A multi-port processor architecture having a first bus, a second bus and a central processing unit. The central processing unit having a first and second ports coupled to first and second busses respectively. A first bus to second bus bi-directional interface couples the first bus to the second bus. Optionally, the first bus or the second bus can be connected to a memory. The architecture can include a third bus with a third bus to first bus bi-directional interface connecting the third bus to the first bus and a third bus to second bus bi-directional interface connecting the third bus to the second bus. If there are additional bus systems, the Nth port (where N is an integer greater than 2) is connected to the Nth port. The buses use bi-directional interfaces to communicate with each other without using CPU or memory resources, reducing memory access latency.

Abstract: A system memory includes a memory hub controller, a memory module accessible by the memory hub controller, and an expansion module having a processor circuit coupled to the memory module and also having access to the memory module. The memory hub controller is coupled to the memory hub through a first portion of a memory bus on which the memory requests from the memory hub controller and memory responses from the memory hub are coupled. A second portion of the memory bus couples the memory hub to the processor circuit and is used to couple memory requests from the processor circuit and memory responses provided by the memory hub to the processor circuit.
Abstract: A core logic device of a computer system includes a programmable interrupt controller (PIC), an input/output advanced programmable interrupt controller (I/O APIC) and a virtual wire unit. The PIC outputs a control signal to the virtual wire unit via an interrupt pin in response to an external interrupt signal asserted by a peripheral device before an operating system is loaded in the computer system. The virtual wire unit outputs an interrupt control packet to the CPU in response to the control signal wherein the interrupt vector contents carried by the interrupt control packet are ignored by the CPU. After the operating system is loaded in the computer system, the I/O APIC outputs another interrupt control packet to the CPU in response to the external interrupt signal.

Abstract: A plurality of memory modules used in a computer system each include a memory hub that is connected to a plurality of memory devices. The memory modules are connected to each other in series so that signals are coupled between the memory modules and the memory hub controller through any intervening memory modules. The signals are coupled to and from the memory modules through high-speed bit-lanes. In the a bit-lane connected to any of the memory hubs is inoperative, the memory hub re-routes signals that would be coupled through the inoperative bit-lane to an adjacent bit lane. When the signal reaches a memory hub in which the bit-lane is no longer inoperative, the memory hub routes the signal back to the original bit lane. In this manner, multiple bit-lane failures can be accommodated using a signal extra bit-lane.

Abstract: Devices are assigned to different buses at development time as well as dynamically during operation, based on actual performance. At development time, bus assignment can be determined based on experiments and direct observation of how devices behave in various configurations. At run time, load on each bus is preferably measured periodically, and when it is uneven, devices are reallocated to different buses. In an alternative embodiment, a user can specify a preference for using more or fewer buses in order to optimize operation for efficiency or lower power consumption.
