中文摘要：
针对传统激光标刻机体积大，运行不稳定等缺点，提出使用嵌入式工控机加运动板卡的设计思路，设计基于CPLD的PC／104总线接口。采用握手通信思想，构造数据读／写权限寄存器，同时结合有艰状态机实现上、下住机数据并行传输。实验仿真证明，传输效果能达到快速稳定，并且实际标刻应用验证了该接口设计的可行性与有效性。
英文摘要：
Aiming at disadvantages Of the traditional laser marking machine such as bigger in size and running unstable,an idea that using embedded computer and the board of motion controller is proposed,and PC/104 interface based on CPLD is designed. Using the idea of handshake,a data register that decides readwrite is structured and data parallel transmission with the finite state machine is realized. The simulation proves that the data access is rapid and stable, The application results show that the design of interface is efficient and feasible.
