Design and Implementation of the Infrared Remote-Controlled Digital Clock Based on FPGA

The digital clock is a clock designed by digital circuit. Now, there are some limitations in the use and regulation of the digital clock in the large square. In this paper, the infrared remote-controlled digital clock based on FPGA can solve this problem well. This digital clock is composed of three parts: infrared remote control module, main circuit of the digital clock and function modules. And it is designed by the VHDL hardware description language, in the Quartus II software development environment.In addition, the digital clock has many extended functions, such as the hour timekeeping, alarm clock and temperature measuring. Besides, it has many advantages, including stable system , simple structure, short development cycle, fast speed and the strong usability.
