摘要： Data is transmitted between a first device and a second device connected by the communications channel in a computer system. The first device generates a first clock and the second device generates a second clock. The first clock is provided to the second device and the second clock is provided to the first device. Data received by the first device over the communications channel from the second device is synchronized to the first clock. The receiving logic in the first device includes a first-in-first-out buffer The received data is stored in a first-in-first-out buffer until the data is synchronized to the first clock. The first and second clocks have the same frequency.

摘要： Access to a bus in a computer system having a CPU and bus devices capable of running cycles on a bus is controlled by an arbiter. The arbiter grants access to the bus according to an arbitration scheme that depends on whether a request for the bus is pending from the CPU, in which a first arbitration scheme arbitrates between the bus devices, and wherein a second arbitration scheme arbitrates between the CPU and at least one other bus device if the CPU request is present.

摘要： A device causing a faulty condition in a computer system having devices is isolated by detecting for a faulty condition associated with the devices and identifying the device causing the faulty condition. The devices are coupled to a bus. The faulty condition includes a bus hang condition. The devices are turned off when a bus hang condition is detected. The devices are then turned back on to test the devices. Each device is tested by writing and reading its configuration space. Information on the bus associated with the faulty condition is stored. The stored information is retrieved after the faulty condition has occurred, with the stored information including address, data, and bus control information.

摘要： A computer system which includes a direct memory access (DMA) controller which can provide a 32 bit memory address and yet can also provide 24 bit memory address operation to remain compatible with previous systems. The DMA controller also monitors system operation and if only 24 bit address operations are occurring under the control of an external bus master or the DMA controller, the DMA controller drives the top memory address byte provided to a cache memory controller to help insure cache coherency. Additionally, the DMA controller can provide optimal time transfers for word width transfer between an odd starting memory address and an even starting input/output port.

摘要： Performance of a bus in a computer system is monitored. A predetermined total period is counted, and usage of the bus for data transfers during the total period is measured. The bus is monitored for active cycles and a period is counted in which the active cycles are present during the total period. The bus is monitored for data transfer cycles and a period is counted in which the data transfer cycles are present during the total period. Bus efficiency is measured based on the active period and data transfer period. Read data usage on the bus is also measured. A first amount of data read by a first device is monitored, and a second amount of read data used by a second bus device is monitored. The read efficiency is determined based on the first and second amounts.

摘要： Control is switched from a first server to a second server in a fault tolerant system. The first and second servers are coupled with an expansion bus in an expansion box for communication with the expansion bus. An indication is provided to the second server to indicate the activity state of the first server. Communication between the first server and the expansion box is disabled if the indication indicates the first server is inactive. Communication between the second server and the expansion bus is disabled if the indication indicates that the first server is active. Communication between the second server is enabled if the indication indicates that the first server is inactive. The indication includes a heartbeat message transmitted periodically to the second server. The expansion bus includes a PCI bus.
