The Research Of Spectral Correlation Platform Based On Embedded VxWorks

Embedded System Design plays an important role in modem electric design for its wildly application in national defense, communication, energy sources, industry and telecommunication which can be a signify innovative element in miniaturized and intellectualized equipment.This project aims at establishing a modularized, scalable hardware platform which uses the Embedded OS VxWorks and ARM micro-processor, for signal detection and parameter estimation in multitask environment basing on real-time system.First to present arithmetic which has been given emulator in Matlab, can be used in making sure of cyclic spectrum correlation technology to detect BPSK and estimate its paramet(?)r. Second to give a introduce of hardware platform design, that included S3C4510B chip as kernel and other function modules, so as to finally get a Embedded signal processing platform supplying network transmission.The design of this platform gives the relative information of BSP (Board Support Packet) and explains BSP for the operating system—Vxworks, the steps of its startup and emphasizes on the design of BSP for this platform. The design of the embedded network platform which used S3C4510B chip and Vxworks system is given. Realization theory of END in VxWorks Operating System and its architecture are analyzed. The way of how to develop the END for this platform is described reasonably. Later gives the model of application for signal detection and parameter estimation in multitask-environment of the Embedded OS VxWorks detailedly.Give a method of getting embedded system and signal processing together which goes throughout theory to platform. It can be a reference for other embedded platforms.
