介绍基于S3C44B0控制的大型LED显示系统。数据传输采用并行总线方式，并提出将LED显示模块厦显示锁存单元虚拟地视为一段连续的存储单元，利用S3C44B0内部DMA控制器进行数据传输和控制，节省使用指令传输数据额外的软件开销，使其具有传输速度快、效率高的特点，以达到用单CPU系统代替多机系统控制LED显示系统的目的。
-S3C44B0 introduced based on the control of large-scale LED display system. Parallel data bus mode, and LED display module will show the latch unit building be regarded as a continuous period of virtual storage unit, the use of S3C44B0 internal DMA controller for data transmission and control, to save data using the command additional software overhead to have a transmission speed, high efficiency, so as to achieve a single CPU system to replace multi-system control purpose LED display systems.
