中文摘要: 基于FPGA 嵌入式系统,在PowerPC 架构的Linux2.6 操作系统环境下,对通用输入输出接口(GPIO)控制器的驱动,采用平台设备机制进行中断控制管理。通过该管理机制,将GPIO 设备本身的资源注册进内核,由内核统一管理。在参照Linux2.6 内核源码有关平台设备驱动的基础上,编写和测试了GPIO 设备的驱动程序。该驱动程序已在Xilinx 公司FPGA 开发板ML403 上验证,并且稳定运行。
Abstract:Under the PowerPC architecture Linux2.6 operating system based on FPGA embedded system, the platform devices mechanism is used to control the driver of GPIO controller by interrupt. With this mechanism, the GPIO registers its own resources into the kernel, and generally managed by the kernel. In reference to the Linux2.6 kernel source about platform device driver, compiling and testing of the GPIO device driver. The driver has been verificated in the Xilinx company's FPGA development board ML403, and operates stably.
