GPMC总线在AM3354与FPGA接口应用中的Android驱动实现

摘要

For the hardware platform of combining AM3354 processor with FPGA, a design of GPMC bus driver program in Android is proposed. The structure principle of GPMC bus and the design idea of system interface are discussed,and the development process and method of bus driver are analyzed. The design of GPMC bus driver program is completed in Android including the addition of the Linux kernel layer and the call of the Android HAL layer,and the key implement code is showed. GPMC bus driver program in Android system works well and finally achieves the intended goal.%针对以AM3354处理器与FPGA相结合的硬件平台,提出Android下GPMC总线驱动程序的设计方案.论述了GPMC总线结构原理,系统接口设计思路,分析了总线驱动程序的开发流程和方法.完成了Android下GPMC总线驱动程序的设计,包括Linux内核层的添加和Android HAL层的调用,并给出了关键实现代码.Android下GPMC总线驱动程序运行良好,达到预定目标.
