| Abstract: | 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. |
