摘要
基于AT89S52单片机和EPM7128SLC84可编程逻辑器件实现LED显示屏的硬件设计。EPM7128SLC84的应用,简化了系统的结构,提高了显示扫描速度。采用VerilogHDL对EPM7128SLC84进行编程,实现LED显示屏扫描控制模块的软件设计。
Design of LED display is based on AT89S52 and EPM7128LS CPLD. The application of EPM7128LS can simplify the system's structure. In the meantime, display scanning velocity is also improved. EPM7128LS is programmed with Verilog HDL. By this way, software design of the scan control unit of LED display is implemented.
