龙芯2 号处理器系统优化关键技术摘　要　系统软件作为处理器和应用程序之间的接口,对于充分利用处理器的特性来维护处理器与应用

程序的稳定性和提高应用程序的性能起着极其重要的作用1 描述了在Linux 内核中解决龙芯2 号处理

器的Cache 别名问题的方法以及通过增加页的大小、软TLB 和FAST TLB REFILL 的方法减小TLB

失效的性能损失,还有Uncache Accelerate 对媒体播放软件的加速1 实验结果表明,在系统软件中增加

这些方法的支持,对系统的稳定性和性能都有较大的好-Godson-2 processor system optimization software summary of key technologies and applications as the processor interface between the processor to take full advantage of the characteristics of the application processor and the maintenance of stability and improve application performance plays a very important role in a descr iption of the Linux kernel to solve the Godson-2 processor Cache alias issues, as well as by increasing the page size, soft TLB and FAST TLB REFILL methods to reduce loss of TLB performance failure, as well as Uncache Accelerate Media Player software to speed up the 1 The experimental results show that an increase in the system software to support these methods, the system has greater stability and good performance
