基于双通道外部总线接口的LCD显示设计

Design and Implementation of LCD Display Based on Dual External Bus Interface

以带有双通道外部总线接口的AT91SAM9263芯片为例,提出一种新的利用双通道外部总线接口实现LCD显示的方法。给出硬件电路、bootloader和Linux kernel等的具体实现,并测试系统性能,说明了双通道外部总线接口在提升系统性能方面的重要作用。

Take an experiment with AT91SAM9263 which has dual external bus interfaces as an example,this paper proposes a novel method to realize LCD display with dual EBI.the mechanism of the design is demonstrated by describing the implementation of hardware circuit,bootloader and Linux kernel.The test result of the system proves that the dual EBI can improve the system's performance efficiently.
