Perf在龙芯2F上的设计与实现
Design and Implementation of Perf on Loongson 2F
摘要
Abstract
This paper designs and implements Perf on Loongson 2F. Perf is a tuning tool on linux. It analyses the implementation of Perf, and modifies the codes related to hardware architecture. It designs functions to control the performance counter in Loongson 2F and handle the overflow interruptions. The results of matrix multiplication sampled by Perf are close to the theoretical values, and more accurate than these sampled by Oprofile.关键词
