基于C54X的DSP载波数字解调系统的设计，该硬件系统工作稳定，可以实现信号的实时处理，如可以实现语音信号的实时处理，通信信号的实时调制解调灯。在此基础上，为了验证DSP芯片的高性能，在此硬件平台上实现了两个具体应用：一个是高性能的FIR数字滤波器；一个是2FSK数字解调算法的实现。-C54X DSP-based carrier digital demodulation system design, the hardware system stability, can achieve the real-time signal processing and if we can achieve the real-time speech signal processing, real-time communications signal modulation and demodulation of signals. On this basis, in order to verify the high performance DSP chips, the hardware platform to achieve two specific applications : is a high-performance FIR digital filter; is a two FSK digital demodulation algorithm.
