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.
