LED display LED dot matrix modules or pixel unit consisting of a modern high - tech flat panel display screen . In recent years , LED display with its high brightness , low energy consumption , low failure rate , configuration flexibility , long service life , display diverse and rich display features in the design and application of rapid development. The same time, as technology continues to progress , LED display is moving high brightness , full color , standardization , standardization , diversification of product structure direction . With the continuous development of the information society , the LED display will get a broader space for development and application areas . The topic for the inadequacies of the existing LED display control system based on Ethernet physical -chip , FPGA and its control chip Fast Ethernet transmission sent the motherboard and the receiver between the motherboard control system . Meanwhile , the control system to continue to use the 32-bit high-performance ARM microprocessor chip as its control core , big screen dynamic display ; receiver board FPGA chip is responsible for generating the scan logic of the LED display . The program makes full use of the respective advantages of ARM and FPGA , system control functions and data processing functions more efficiently , so that the whole system more flexible configuration , resource richer , broader applicability and ease of use . According to the needs of the system , the subject considering the existing technical support , device characteristics , system cost , and facilitate the procurement of various factors , and select the appropriate device , complete control system hardware platform . Meanwhile, in the FPGA in the control system is divided into a number of functional modules, and the elaboration of the program of each part of the implementation . Finally, all functional modules in the system after a systemic simulation , synthesis, and hardware debugging , to achieve the desired objectives .
