Abstract:
A system for transferring Peripheral Component Interconnect (PCI) formatted data over a non-PCI bus, the system comprising:a non-PCI bus comprising an address bus and a data bus for communicating addresses and data; a Peripheral Component Interconnect (PCI) compatible peripheral coupled to the non-PCI bus for transmitting and receiving PCI-compatible data; a slave device coupled to the non-PCI bus for receiving and transmitting PCI data and non-PCI data; a byte size control line driven by the PCI-compatible peripheral and coupled between the PCI-compatible peripheral and the slave device for indicating whether data appearing on the non-PCI bus is from the PCI-compatible peripheral; and a bus byte enable (BBE) driven by the PCI-compatible peripheral and coupled between the PCI-compatible peripheral and the slave device for indicating which bytes on the data bus are valid; wherein the slave device decodes the byte size control line and the BBE to accept only valid bytes of the PCI-compatible data appearing on the data bus.
