FPGA的RC-6红外遥控多种协议解码设计

Design of RC-6 Infrared Remote Control Protocol Decoding Based on FPGA

随着消费电子的快速发展,红外遥控应用越来越广泛。目前红外解码基本采用专用解码芯片,对不同的红外遥控协议更改不方便,实现起来不灵活,而基于FPGA的红外解码设计可以方便应对这种情况。本文以RC-6作为应用红外遥控协议解码,阐述了如何方便地用FPGA实现RC-6解码,集成到系统中并显示它可以适应多种红外遥控协议系统,该方案占用资源少,实时性好,实现方便灵活。

With the rapid development of consumer electronics,infrared remote control is more and more widely used in our electrical equipment.In most of electrical equipment,the infrared decoder is based on a special chip,so it is not convenient to implement with difference infrared remote control protocol,and the infrared decoding design based on FPGA can be easily implemented in this case.Taking RC-6 infrared,a remote control protocol as an decode example,this paper shows how to implement RC-6 decode with FPGA and integrate it into the equipment system.It shows that it can be designed to match to difference of infrared remote control protocol systems,it takes less FPGA resources,has good real-time performance,and it is convenient and flexible to implement.
