摘要： Provided is a method of streaming transfer of data between a plurality of devices of a computer system. The method includes providing data to be sent from a source device to a target device and includes receiving, at the source device, one or more transfer credits from the target device. A transfer credit may be indicative of an amount of data that the target device is authorizing to be sent to the target device. The method also includes determining whether or not an accumulated transfer credit value satisfies a threshold value. If the accumulated transfer credit value satisfies the threshold value, the source device sends data to the target device and modifies the accumulated transfer credit value based on a quantity of data sent. If the accumulated transfer credit value does not satisfy the threshold value the source device does not send data to the target device.

摘要： A PCI bus to IEEE 1394 bus translator for coupling a PCI device to a host computer via an IEEE 1394 bus. The translator translates addresses of PCI bus cycles initiated by the PCI device into 1394 memory addresses and performs data transfers between the PCI device and host computer by exchanging 1394 request and response packets with the host computer using the translated 1394 memory address. The translator also translates 1394 memory addresses of 1394 request packets received from the host computer into PCI cycle addresses and performs data transfers between the PCI device and host computer by initiating PCI bus cycles targeted at the PCI device using the translated PCI bus cycle addresses. The translator posts data from sequential PCI bus write cycles initiated by the PCI device into a write-posting FIFO until granted ownership of the 1394 bus. The translator combines the PCI write cycle data into a single IEEE 1394 write request packet and transmits the packet on the 1394 bus to the host computer. The translator, if configured to a first mode, pipelines subsequent PCI bus write cycles by posting the PCI write cycle data into the write-posting FIFO once reception of the first 1394 write request packet has been acknowledged by the host computer but prior to the host computer responding with status indicating the completion of the write transaction, in particular whether or not a resource conflict occurred. In response to a PCI read cycle initiated by the PCI device, the translator pre-fetches a larger amount of data than specified in the PCI read cycle from the host computer into a pre-fetch FIFO in order to satisfy subsequent PCI read cycles which are in address sequence with the previous PCI read cycle. The translator pre-fetches more data from the host computer once the pre-fetch FIFO becomes a predetermined amount empty in order to pipeline the consumption of the pre-fetch data by the PCI device and the transmission of the pre-fetch data by the host computer to the translator.

摘要： A Wide Area Serial PCI system for connecting peripheral devices to a computer. The WASP system includes a host computer system connected through a serial bus to a remote device. The serial bus can range from several meters to several kilometers or more. The host computer system includes a CPU and memory, and also includes a first Peripheral Component Interconnect (PCI) bus, also referred to as the local PCI bus. A primary bridge according to the present invention is coupled to the first PCI bus. The primary bridge includes PCI interface circuitry for interfacing to the first PCI bus. The remote device is located remotely from the computer system and comprises a second or remote PCI bus and one or more peripheral devices coupled to the second PCI bus. The remote device also includes a secondary bridge coupled to the second PCI bus. The secondary bridge includes PCI interface circuitry for interfacing to the second PCI bus. The serial bus is coupled between the primary bridge and the secondary bridge. Each of the primary bridge and secondary bridge include parallel/serial transceivers for converting parallel data generated on the first PCI bus and second PCI bus, respectively, to serial data for transmission on the serial bus and for converting serial data received from the serial bus to parallel data for generation on the first PCI bus and second PCI bus, respectively. The primary bridge and the secondary bridge collectively implement a PCI—PCI bridge register set.

摘要： A mechanism for managing packetized data transfers in a system including a transmitting and a receiving device. The transmitting device may transmit data to the receiving device in a plurality of packets, each packet a predetermined number of data bytes wide. The transmitting device may include a transfer count unit to maintain a data transfer count based on a number of transmitted data bytes. The receiving device may program the transmitting device with a transfer count mark, which may be a number that corresponds to a specific count of the data transfer count. The transmitting device may calculate a difference between the data transfer count and the transfer count mark. If the difference between the transfer count and the transfer count mark is less than the predetermined number, the transmitting device may transmit a short data packet having less than the predetermined number of data bytes to the receiving device.
