Abstract

As the interface between applications and processor, system software plays an important role in maintaining the stabilization of processor and improving the performance of applications. In this paper, ways to resolve cache synonyms in Godson-2 processor and methods to decrease performance loss resulting from TLB miss, such as augmenting the page size, software TLB and FAST_TLB_REFILL, are described. And a way of Uncache Accelerate for improving performance of video output is depicted. Experimental results show that these kinds of methods in system software can benefit the stabilization and performance of the computer system.
- Godson-2 processor,
- cache synonyms,
- software TLB,
