摘要:
A computer system has a processor bus under control of the microprocessor itself, and this bus communicates with main memory, providing high-performance access for most cache fill operations. In addition, the system includes one or more expansion buses, preferably of the PCI type in the example embodiment. A host-to-PCI bridge is used for coupling the processor bus to the expansion bus. Other buses may be coupled to the PCI bus via PCI-to-(E)ISA bridges, for example. The host-to-PCI bridge contains queues for posted writes and delayed read requests. All transactions are queued going through the bridge, upstream or downstream. According to a feature of the invention, provision is made for split transactions, i.e., a read request which is not satisfied while the processor requesting it is still on the bus, but instead the bus is relinquished and other transactions intervene before the read result is available. A contemporary microprocessor such as a P6 has a deferred transaction protocol to implement split transactions, but this protocol is not available on a PCI bus. Split transactions are done by a "retry" command on a PCI bus, wherein a read request that cannot be completed immediately is queued and a "retry" response is sent back to the requester on the bus; this instructs the requester to retry (send the same command again) at a later time. To avoid a situation where two processors issue locked cycles which are enqueued and retried in separate bridges, a "Superlock" signal is added to the processor bus, which is asserted by a bridge as soon as a locked transaction is enqueued, and thereafter neither bridge will accept a locked cycle issued by a processor, other than that locked read that was initiated by a processor and enqueued in the bridge and is being retried.

An apparatus and method are provided to perform a time multiplexing logic in a module, are provided including identifying a driving flop and a receiving flop in the module, receiving a modified input signal, and identifying a worst case timing path for the modified input signal to transmit from the driving flop to the receiving flop. The time multiplexing logic of the apparatus and method further identifies a predetermined point of the worst case timing path, and inserts a logic unit at the predetermined point allowing the time multiplexing logic circuit to process and output the modified input signal at a maximum frequency.

An apparatus and method are provided including a point-to-point cluster link configured to receive a data packet and determines a cyclic redundancy code check for the data packet. The point-to-point cluster link is configured to add a cyclic redundancy code check bit to the data packet transmitted to the point-to-point inter-cluster link, to clear the cyclic redundancy code check bit when the data packet is received, and to sample a cyclic redundancy code window to identify a corrupted data packet.

摘要:
A computer system adapted for hot-pluggable components such as memory modules that may be replaced, upgraded and/or added without disturbing normal operation of the computer system. A failing memory module may be replaced by copying its contents to a new memory module in a background operation while the computer system runs its operating system and applications programs. When all contents are copied to the new memory module, the failing memory module may be removed without having to shut down the computer system. Computer system memory may be upgraded or added to by inserting the new memory module(s) into vacant disconnected memory connectors, whereupon the computer system automatically recognizes the new memory module(s), synchronously connects the new memory module(s) to the computer system memory bus, initializes the new memory module(s), and then notifies the operating system that the new memory module(s) is available, all without disturbing normal operation of the computer system.
摘要:
The gas cushion serves to support a preheated glass sheet and is produced by a chamber, which is connected to a source (21) of compressed gas. The upper wall (10) of the chamber is adapted to the shape of the glass sheet and has a plurality of apertures for the passage of gas in the form of nozzles (14), which comprise an entry bore (22) and, following thereupon, a progressively widening exit hole (16) with a nozzle exit area (15). The upper wall (10) of the chamber has a greater degree of perforation (sum of the nozzle exit areas (15) in relation to the total area of the respective zone) in its edge zone (12, 13) than in its central zone (11). The nozzles ensure that no jet marks can arise. The gas of the gas cushion can also flow out undisturbed at the side, so that no cooling edges are present and the occurrence of cooling shadows is accordingly avoided.

摘要:
The glass sheets (2) of an asymmetric glass-sheet pair, which is intended for the production of laminated glass, are preheated in a preheating furnace (1) and then undergo a press-bending process in a press-bending station (4). By means of a temperature measuring point (11) arranged at the exit of the press-bending station, it is ensured that the glass sheets exhibit a uniform bending behaviour, in order to guarantee identical restoring forces during cooling. The temperature measuring point (11) is connected to a control device (16), which causes an intermediate cooling of the glass sheet heating more rapidly by means of an intermediate cooling installation (12, 13) in the pre-heating furnace and/or lengthens its dwell time in the press-bending station (4) by means of a timing control element (15).
