Abstract: An electronic system interconnect. The interconnect comprises a first node and a second node coupled to the first node. The interconnect is initially configured to include the first and second nodes. A third node is added to the interconnect after the interconnect is initially configured, and the first node responds to the addition of the third node by initiating a new connect handshake with the third node. The first node begins by transmitting a first signal to the third node. The first node signals that the third node has been added to the interconnect if the third node responds to the first signal by transmitting a second signal. The first node causes the interconnect to be reconfigured if the third node transmits a third signal in response to receiving the first signal.

The registered hosts are selectively configured to be able to communicate with one or more of the peripheral devices. Communications between applications and the peripherals are transparent in that they operate as if directly attached to a USB port on the host computer.

Abstract: A processor communication register (PCR) contained within a multiprocessor cluster system provides enhanced processor communication. The PCR stores information that is useful in pipelined or parallel multi-processing. Each processor cluster has exclusive rights to store to a sector within the PCR and has continuous access to read its contents. Each processor cluster updates its exclusive sector within the PCR, instantly allowing all of the other processors within the cluster network to see the change within the PCR data, and bypassing the cache subsystem. Efficiency is enhanced within the processor cluster network by providing processor communications to be immediately networked and transferred into all processors without momentarily restricting access to the information or forcing all the processors to be continually contending for the same cache line, and thereby overwhelming the interconnect and memory system with an endless stream of load, store and invalidate commands.

Abstract: The objective of the present invention is to provide a data transfer control device and electronic equipment that guarantee stable operation even if a reset that clears the node topology information occurs. When a CPU (firmware) of a data transfer control device in accordance with the IEEE 1394 standard issues a data transfer start (or resume) command during a bus reset period, the execution of that command is canceled. The fact that the command has been canceled is informed to the CPU by an interrupt. The command is canceled by using a signal that is active during the bus reset period to mask a signal that goes active when a command is issued. When a pause command is issued, the transfer processing pauses at a previously determined pause location. Transfer data is automatically divided into a series of packets to be transferred continuously by the hardware.

Abstract: One embodiment of the present invention provides a system for enhancing the effective timing margins and the reliability of a digital system bus. The system monitors the digital system bus to determine the data flow between devices on the digital system bus. If an absence of data flow is detected, the system generates a pseudo-data signal to replace the normal data signal on the digital system bus. This pseudo-data signal is broadcast on the digital system bus, in order to keep the digital system bus active, thereby preventing subsequent transmissions from suffering from effects caused by an inactive digital system bus.

Abstract: Copy capability moved into the SAN fabric and provided as a data mover service. A well-known address is utilized to receive copy commands from the hosts. Each switch in the fabric contains a front end or service interface. The service interface of the switch connected to the host receives the copy command and manages access control or zoning and LUN mapping. LUN mapping and zoning are based on shared databases. Maintaining single, shared databases among the switches for LUN mapping and zoning greatly reduces administrator burden. By decoupling the need for the host to talk to the copy engine, zoning is greatly simplified as only the switches will be able to send commands to the copy engine, so the copy engine need only be zoned to have access to all of the desired storage devices, with no host access to the copy engine. Assuming correct zoning, the service interface will perform any necessary LUN mapping on the received copy command and forward the command to a copy engine to perform the copy operation.
