17. DUCTION The PCI specification defines two types of PCI devices a target and a master A target is a device that accepts commands and responds to the requests of a master The master or bus master is a more intelligent device that can conduct processing independently of the bus or other devices A bus master device shares the bus with the main processor and targets Bus mastering allows a peripheral device to take control of the system bus and not rely on the central processor The 3C971 F adapter is a bus master device The PCI specification supports the following features a High performance The PCI local bus runs at a clock speed of 33 MHz and employs a 32 bit data bus that supports multiple peripheral components and add in cards at a peak bandwidth of 132 MBps up to an order of magnitude greater than that of other PC buses ISA EISA and MCA a Automatic configuration A PCI adapter has configuration specifications set in on board memory and provides installation information to the computer at start up m Shared slots The PCI specification calls for shared slots which denotes the shared expansion backplate slot This shared backplate slot provides access to one of two types of adapters a PCI adapter and an ISA adapter for example or a PCI adapter and an EISA adapter Only one adapter at a time can be installed in a shared slot Manufacturers are currently producing computers that support the PCI bus in conjunction
