传统的大型LED显示屏系统以单片机MCU、ARM或PLD为核心控制芯片，以FPGA为核心的LED显示屏控制系统设计实现起来比较复杂，并且需要以高性能的FPGA芯片作为基础，而以微处理器为核心的LED显示屏控制系统不够灵活，在改变LED屏幕显示尺寸时，需要大幅修改系统设计，PLD虽在处理速度上有较大提高且能很好地控制多模块显示，但其在时序电路描述方面明显不如FPGA．提出了基于FPGA与单片机MCU的大型LED显示屏系统设计方案，该系统中FPGA为主控制单元，单片机为扫描控制单元，该方案简化电路，提高系统的灵活性和可靠性．实践仿真结果表明：系统显示内容较多，能较好地支持彩色显示，降低了功耗，实现了现场实时控制显示．

The traditional large-scale LED display monitor system takes monolithic integrated circuit MCU,ARM or PLD as the core control chip.It is complex to design the LED display monitor control system which takes FPGA as the core and the high performance FPGA chip is basic for the design.But the LED display monitor control system using microprocessor as the core is not nimble enough,so when changing the LED screen demonstration size,it＇s necessary to revise the system design a lot.Although PLD has a great enhancement in the processing speed and can control the multi-modules to demonstrate well,it is inferior to FPGA obviously in the sequence circuit description aspect.This paper proposes a large-scale LED display monitor system design plan based on FPGA and the monolithic integrated circuit MCU.In this system FPGA is the focus control unit,and the monolithic integrated circuit is the scanning control unit.This plan may simplify the circuit and enhance the system＇s flexibility and reliability.The practice simulation result indicates that the system has great demonstration content and can well support the color display and reduce the power loss.It realizes the on-the-spot real-time control demonstration.
