摘要： A data transfer method and apparatus are provided for transferring data in a computer system on a high-speed synchronous multi-drop bus. Multiple devices including at least a first group of a plurality of devices and a second group of at least one device are connected to the high-speed synchronous multi-drop bus. To transfer data between devices in the first group, a first unidirectional data valid signal is applied to each device in the second group. The data from a sending device in the first group is transferred to a designated device in the second group. A second unidirectional data valid signal is applied to each device in the first group. The data is transferred from the designated device in the second group to a selected device in the first group.

摘要： A method and apparatus for routing data between bus devices, where each bus device is connected to a centralized switch via a point-to-point bus connection. The plurality of point-to-point bus connections collectively form a system bus. After a command is issued on the system bus, each bus device responds to the issued command by transmitting an address status response to a response combining logic module. The response combining logic module identifies which of the bus devices responded with a positive acknowledgment to the issued command, then forwards a device identifier of the bus device responding with the positive acknowledgment to the switch. The switch uses the device identifier returned via the response combining logic to route the data transfer associated with the issued command.

摘要： An apparatus, program product and method initialize a redundant memory device by delaying the switchover of non-initialization fetch operations from a failed memory device to the redundant memory device until after initialization of the redundant memory device is complete. Consequently, during initialization, the non-initialization fetch operations are directed to the failed memory device, while non-initialization store operations are directed to the redundant device.

摘要： An improved computer memory subsystem determines the most efficient memory command to execute. The physical location and any address dependency of each incoming memory command to a memory controller is ascertained and that information accompanies the command for categorization into types of command. For each type of memory command, there exists a command FIFO and associated logic in which a programmable number of the memory commands are selected for comparison with each other, with the memory command currently executing, and with the memory command previously chosen for execution. The memory command having the least memory cycle performance penalty is selected for execution unless that memory command has an address dependency. If more than one memory command of that type has the least memory cycle performance penalty, then the oldest is selected for execution. Memory commands of that type are selected for execution each subsequent cycle until a valid memory command of that type is no longer available, or until a predetermined number has been executed, or until a memory command of another type has higher priority. If an address dependency exists between memory commands of different types, then memory commands of the same type of the oldest memory command is executed to avoid deadlock.

摘要： A shared bus non-sequential data ordering method and apparatus are provided. A maximum bus width value and a minimum transfer value are identified. A minimum number of sub-transfers is identified responsive to the identified maximum bus width value and the minimum transfer value. A bus unit having a maximum number of chips to receive and/or send data receives data in a predefined order during multiple sub-transfers. During each data sub-transfer, a corresponding predefined word is transferred to each chip of the bus unit.

摘要： A method and system for arbitrating data transfers between devices connected via electronically isolated buses at a switch. In accordance with the method and system of the present invention, multiple arbitration controllers are interposed between devices and a switch to which the devices are connected, wherein each of the multiple arbitration controllers are effective to select a data transfer operation and detect collisions between said selected data transfer operations. The switch is enabled for any selected data transfer operations between which collisions are not detected. The switch is also enabled for only one of the selected data transfer operations between which collisions are detected. Any selected data transfer operations for which the switch is not enabled are deferred. The deferred data transfer operations are prioritized within the multiple arbitration controllers, such that for a subsequent selection of the deferred data transfer operations, the switch is enabled for the deferred data transfer operations.
