Abstract: This paper introduces a new method, using Complex Programmable Logic Device to attach a precise time label for sample data in very high-speed sample data system. It has used MAX PLUS II to simulate the function and it has been proved to be accurate. The system has been applied in high-speed data sample board, which has been designed successfully.
