摘　　要：介绍一种基于现场可编程门阵列(FPGA)的多通道电子数片机设计方案.系统利用FPGA丰富的逻辑资源和快速并行处理能力实现信号调理、逻辑判断、对象控制等功能.片上嵌入了CPU软核负责参数处理及数据通信.在对系统控制要求和影响性能指标因素的分析基础上,论述了FPGA中控制逻辑的设计和可编程片上系统(SOPC)的构成,并给出了部分电路的原理图和仿真波形.A design project based on Field Programmable Gate Array （FPGA） for multi-channel electronic tablet counter is introduced. The project takes the advantage of abundant logical resource and high-speed parallel processing capability of FPGA to carry out a number of functions such as signal regulation, logical judgment and object control. An embedded soft-core of CPU is used to implement the data processing and communication. Based upon the analysis about the requirements of the system control and the key factors affecting the system performance, the detailed illustration on the systematic configuration of system on programmable chip （SOPC） and the logic control circuits in the FPGA is provided associated with some circuits schematic diagrams and the simulation waveforms.
