HDL Design and Post Simulation of IrDA Circuit

Along with development of wireless communication technologies, IrDA transmission technique has been applied in an increasing number of relevant fields, resulting in urgent demands for more highly efficient designing and simulation methods. In this paper, the technology of IrDA protocol group is specifically described, an IrDA encoder and decoder circuit with HDL language is designed. The logic functions and timing sequence are consistent with the requirements of design specifications, and the result is confirmed by comparing the post simulation with the wave form. Using the HDL language, the proposed design is characterized in significant simplicity and efficiency. In addition, the proposed design can be readily implemented with PLD and a number of applications have been seen in embedded systems.
