PCI Bus Prototyping Card (1)
The development of a PCI based expansion card is relatively complex and usually needs a large investment of time and money before success is achieved. The PCI prototyping card presented here offers a more convenient solution. Its pre-configured PCI decoder and 16 bit wide data bus together with a series of port addresses allows you to concentrate on development and testing of your prototype circuit without getting bogged down in the detail of the PCI bus standard.The Peripheral Component Interconnect or PCI Bus is a relative newcomer to the computer interface world but has rapidly replaced the older and well known ISA Bus. One attractive feature for peripheral designers is that this bus is used not only for IBM compatible PCs but also for workstations and Apple Macintosh systems. Basically, the interface is a very powerful multiplexed 32/64 bit wide address/data bus. One of the original aims of this bus standard was to ensure that it would not become obsolete overnight and would still be in use after many generations of processor have come and gone.
