Abstract:
This project presents a brief review of the main types of buses used in the computer explaining the features, characteristics and the historical progression include them, and what distinguishes each bus from others Particularly in terms of rate of data transfer speed, under which is the development and modernization in the buses to meet the steady progress in the speed of the microprocessor.
The focus was on the PCI local bus, by explaining its benefits and its importance and to highlight the points of superiority over other buses and to identify the input and output signals and processes addressing and configuration, read and write.
PCI sound blaster card has been connected (Interfacing) to a computer. And through the operations of read and write has changed the values of the registers for the sound card through a program written by (Assembly language) , causing a change in voice characteristics.
