1553b Bus Interface Board Based On The Pci Bus Design

In recent years, the integrated avionics system has been continuously developed and improved with the development of science and technology. Since the 1553B bus interface board plays a key role in the realization of integrated avionics system, its design is quite important. Meanwhile, because of the PCI local bus' s special design which is independent of CPU and also because of such advantages as the high performance, low cost and open architecture, PCI local bus becomes so popular that currently has become the actual PC bus standard.This thesis is concerned with the hardware and software design of the 1553B bus interface board based on PCI bus and it can be divided into six chapters. Chapter One summarizes the main content and the significance of the research; Chapter Two introduces PCI bus and 1553B bus in detail; Chapter Three gives a general presentation of the design principle and introduces the PCI bus interface chip S5920 and 1553B bus protocol chip BU-61580 in detail, which make a basis for the hardware and e software design in the following chapters; Chapter Four shows how to design the board' s hardware by using PCI bus interface chip S5920 and 1553B bus protocol chip BU-61580; Chapter Five deals with the concept and design method of VxD (virtual device driver), as well as the communication method between the user' s application and the device driver; the last chapter, Chapter Six mainly puts forward some suggestions on how to improve the system.
