摘　　要：本文以双核处理器OMAP-L138为核心,设计了一款新型的实时高速车载机车信号处理系统。该系统可以精确地研究与开发轨道信号的发送、接收、解调等工作。其独特的板卡式设计提高了系统的灵活性和扩展性。通过对ZPW2000A信号的解调证实了系统达到了预期目标。With the dual-core processor OMAP - L138 of TI company as the core, it was designed a new kind of high-speed on-board Locomotive Signal Processing System in real time. On the structure, the flexibility and extensibility was improved by the unique board card design of the System. In this article, the reach of the expected goal of the System was demonstrated through the implementation of ZPW2000A signal demodulation.
