The infrared remote system design based on FPGA

One design method of infrared remote control is introduced which is based on field programmable gate arrays FPGA devices. The paper gives a construction method for infrared remote system. The system uses PT2248 as a transmitter, MIM-R1AA38kHz integrated infrared receiver demodulator as a receiver. Then it explains how to use EDA technology top-down design approach to achieve infrared remote control decoder chip, decipher, key in, number reveal and alarm function of briefing on etc. The paper also details in features and performance of ALTERA DEII platform, at the same time use the Cyclone II ?of EP2C35F672C6N to realize the whole system on DE2 board with the EDA tools.
