Abstract

This invention provides a method and implementation of adding more devices to a Peripheral Component Interconnect (PCI) bus than the existing system arbiter can handle. It does so by sharing multiple request/grant pairs on one of the arbiter's request/grant lines. The invention provides methods and implementations of two kinds of fairness strategies to ensure that the devices that are sharing the one request/grant pair get fair access to the bus.
