Research On Signal Processing Platform Based On Embedded System

The open computer system (include the embedded system) is combined with open embedded Linux, will bring a kind of brand-new design philosophy for communication equipment, reseach and development which will consume the electron, control system, and military apparatus products of future generation, and have very great application prospect in the above each field. The whole embedded apparatus includes for the hardware platform of the embedded processor and operating the embedded software on the embedded processor. We can develop the driver and application program on it if there are embedded operating systems.In the actual project of underwater acoustic, digital signal processor is used to realize the signal collection, processing, analyzing, etc. The ordinary computer finished some simple human-computer interaction functions, but cost paid at the same time is huge volume and very high power. For this reason, we can substitute the ordinary computer with the embedded system, for guaranteeing to have the same serviceability and dependability with the ordinary computer, have reduced the volume and power.This thesis takes this one as the background, have carried on research to the digital signal processing system based on embedded PXA255/Sitsang platform of Intel Company, the content studied includes the following several respect mainly: 1.Design and debug the digital signal platform that PXA255/Sitsang should expand.2.Setting-up in Linux operating system with PXA255/Sitsang platform development environment and programming of character device driver. 3.application program of control and display on the basis of the MiniGUI.
