摘要
在CQ8401硬件平台和嵌入式Linux系统下,提出了NVRAM的实现方案,并设计实现了新的NVRAM的驱动。针对NVRAM的功能特性,利用嵌入式Linux平台,设计设备驱动程序与操作系统及外部设备的接口,实现了应用软件对硬件的正确的访问操作。对系统的性能进行了分析,并对结果进行了测试。该方法已成功运用于使用CQ8401开发板的网络路由器中,运行效果良好。
The realization of a approach of NVRAM, and its design of driver in the embedded Linux environment based on the CQ8401 platform is expounded. According to the characters of NVRAM, the interfaces between the device driver and system kernel, peripheral devices are also designed in embedded Linux. Application software operate the hardware correctly. The performance of system is analyzed and the result is tested. The solution is implemented in router with CQ8401 develop board and got good results.
