The Design And Implementation Of Multifunction DSP Development And Experimental Platform

This dissertation designs and implements the Multifunction DSP experimental platform based on the frame of DSP+CPLD by analyzing the requirements of the digital signal processor integrated system and the real needs of leakage signal processing.The idea of modularization design is mainly infused in the hardware designs of this experiment platform. It contains two parts:one is the minimum system module, which takes TMS320VC5416-160 as the core chip; the other is the system host board. The first part constitutes a suite of the independent DSP control system, which carries out the functions of the real-time programming, debugging, simulation and BOOTLOADER loading with the JTAG interface on CCS platform. The hardware resources of the system host board include the keyboard matrix module, the liquid-crystal display module, the dual channel audio signal acquisition and processing module, the power supply module, CPLD control module and etc. The programs of software are written with C language, assemble language and hybrid programming. In addition to the general routine of the experiments, the BOOTLOADER loading of DSP and composite application between modules are added.The most important distinguished characteristic of this experiment platform is that it designs two sets of TLV320AIC10 data acquisition chips matching with the DSP, which can manage the data real-time acquisition and process of the dual channel audio. It offers a rich hardware support for specialists to program and design, such as:collecting data acquisition, filtering (FIR, IIR), removing noise, correlation operating, coding and decoding, FFT transformation and etc. This dissertation focuses on the hardware circuit designing and the software programming designing proposal of the liquid-crystal display module on this platform, as well as the BOOTLOADER designing method on the DSP control system. The programming skills of downloading the BOOT header with twice time downloading method are successful implemented into the user programs. This dissertation not only came true the effective bootloader loading and running, but also explained the puzzles in the process of BOOT designing and loading to research personnel. The rich hardware and software resources as well as advanced design concepts spur it to a multi-function DSP development and experiment platform with effective, perfect in shape and function, friendly interface.
