摘　　要：介绍一种增量式编码器信号处理系统,实现了对编码器信号四倍频鉴相、计数以及复位等操作,最终计数结果可以通过EMIF接口上传至上位机。利用Modelsim仿真软件和测试平台进行了仿真测试,并对实验结果进行了分析。结果表明,该设计计数结果准确可靠,具有较强的抗干扰能力。A signal processing system of incremental encoder is introduced, which can realize the operations of fourfold fre- quency phase discrimination, counting and reset. The final counting results are uploaded to the upper computer via EMIF inter- face. The design was simulated with Modelsim software and tested on the test platform. The experimental results are analyzed, and show that the counting value of this design is accurate and reliable. The system has strong anti-interference ability.
