But in the system with a lot of high-speed real-time data, due to a single chip processing speed limit is ragged. In order to solve these problems, this paper puts forward a DSP control based on the design of the LCD screen, effective to solve the above problems. This paper put forward based on DSP control liquid crystal display (LCD) digital simulation clock design. Through to the digital signal processor (DSP) TMS320L VC5416PGE and LCD module LCM12864ZK analysis and research, using the least TMS320L VC5416PGE DSP system board has constructed a time display system, adopting LCM12864ZK LCD module show time, with buttons settling time. This clock system including the realization of hardware circuit and system programming design two parts. On liquid crystal display clock system hardware principle and main program flow chart are presented, and gives the timer and initial program according to LCD module interface, speaking, reading and writing in digital signal processor (DSP) the timing write TMS320L VC5416PGE on liquid cr
