Design and Realization of WiFi Module on Loongson-3A Architecture

摘要:

为提高军用国产计算机的移动计算能力,提出一种在龙芯3A体系架构下WiFi模块的软硬件设计方法;在硬件设计部分,该WiFi模块围绕AR9285芯片展开设计,通过PCI-E总线与北桥进行连接；在软件设计部分,通过在PMON中添加WiFi模块驱动,实现初始化、数据发送和接收等功能;验证结果表明,移动计算机能够通过WiFi模块远程加载操作系统内核,无线网络数据响应时间约为1.5 ms。

Abstract:

To improve the mobile computing ability of military computer, a new hardware and software design method of WiFi module on Loongson-3A architecture is proposed. The hardware design of WiFi module is based on AR8285 chip. The software design is based on WiFi driver in PMON, include the function of initialization、send and receive data. The result proves the wifi module can work stably, can effectively improve the mobile computing ability.
