摘要
目前各种LED显示器常采用8位/16位的微处理器,由于其运行速度、寻址能力和功耗等问题,已难满足显示区域较大、显示内容切换频繁的相对较复杂的应用场合。采用32位ARM嵌入式微处理器S3C4510B和32位FPGA扫描驱动电路芯片PolarPro QL1P300,选用IS61C1024静态RAM作为缓存器,组成由多块大屏幕LED显示器构成了新的显示系统。该系统在不增加成本的情况下,可支持更大可视区域的稳定显示,存储更多显示内容。
Now 8-bit or 16-bit microprocessors are often used to control the large LED display screens. Because of some problems existing in the microprocessor system such as running speed, addressing capacity and power lost, it is difficult to satisfy the requirements in the complex occasions of larger display area and the contents of display switched more frequently, A display system formed easily with large LED display screens was designed with 32-bite embedded microprocessor S3C4510B and 32-bit FPGA scanning drive circuit chip, and IS61C1024 static RAM was chosen as the buffer. The system can support steady display with bigger displaying area and store more display contents while adding no more costs.
