The Design And Application Of The Multiple DSP Parallel Processing System Based On The Standard PC/104 Bus

Aiming at the application in the area of the integrated navigation ,this paper developed a multiple DSP parallel processing system based on the standard PC/104 bus .In addition ,this paper applied the embedded multiple DSP parallel processing system into the inertial/gravity match integrated navigation and tested the multiple DSP parallel processing system's capability when it was applied into the area of the integrated navigation.This paper mainly focused on the following aspects:(1) Research and develop the hardware platform of the multiple DSP parallel processing system based on the standard PC/104 bus .Analyzed some multiple DSP parallel processing system's structure ,this paper chose the distributed and memory share structure .This system's design is divided into three parts :host,distributed processing and coding of the system's interface .(2) Research and develop the software platform of the embedded multiple DSP parallel processing system .This section resolved some questions like communication and data exchange between PC/104 computer and DSP.(3) Analyze and research the inertial/gravity match integrated navigation system ,and develop the program in C language according to the navigation arithmetic.This program developed in PC platform was divided into three parts :inertial navigation,gravity match,Kalman filter .(4) In order to apply the integrated navigation system into the multiple DSP parallel processing system ,this paper redesigned the program ,including modified the programs of th inertial navigation,gravity match and Kalman filter ,and add the system control.At last ,this paper successfully applied the multiple DSP parallel processing system based on the standard PC/104 bus into the integrated navigation .
