The Research Of The Rebootload Technic In Locale Based On The Processor Of Image

This task gives the research to the way of locale relocation based on image process system of guided storehouse of guided missile, and the core of image processor mainly includes DSP and FPGA, and the two parts need some software to cooperative to make the system to be more flexible and have a powerful function, and the process for upgrade and rewriting we call it locale relocation.This article studies and discusses various schemes using different interface to relocate the system, and analyzes and compare its advantages and disadvantages, and finally realizes a scheme to relocate the primary system through USB 2.0 interface. Taking a piece of Xinlinx VirtexⅡ,series of FPGA ,as the core of the system ,connecting with a piece of 6200 DSP of TI, and USB 2.0 chipset complete the system′s expanding using EX-USB FX2 of Cypress, and give experimental research on predigested system.This article brings forward the way solving system relocation, and analyzes the advantages and disadvantages of each method through experiment. As the theoretic base ,we give some common introduce to the pivotal chipset used in the system ,such as USB 2.0 chipset,6200 series' DSP and FPGA of Xinlinx, and through FPGA inner logic it not only make Data Bus of 68103 connected with the XBUS interface of DSP, but also make the system relocated through the way by expanding USB in the original system ,and then the article analyzes the way of relocation of hardware and software when using USB 2.0 chipset, and detailed discusses the method to lead and relocate DSP.About system realization, the article divides it into two parts to introduce detailedly, that is USB 2.0 communications and relocation of DSP. About USB 2.0 communications, it introduces hardware connection between this chipset with FPGA which is the core chipset in the system, and the way of communications in each part of the system, and then emphatically introduces the design of correlative firmware and the design of drive and some applied software, which ensure the USB reliably communicating. About relocation of DSP, the system uses scheduling characteristics and the way of collocation, and it validate feasibility of this system though an examination.About system debugging, this article introduces some tools for exploitation and debugging used for this system including CCS, ISE and EZ-USB the debugging tool for USB, and the methods to solve any correlative problems meeting in debugging, and analyze the matters when happened during making the high-speed board.
