摘要

Topic Method and the device for stride profiling of software application are offered.SolutionsWith one example of the system, the hardware performance counter is used in order to report with instruction address and the data address which it is related to the memory access order which occurred due to a some event such as data cash mistake. When the same instruction address is related to the data address of two or more, difference between two data addresses is reported. When the data address difference of those two or more is recorded vis-a-vis the same order, the system decides the stride which it is related to the order which becomes greatest common divisor of the difference of two or more. This stride, in order to optimize data cash pre- fetch, can also be used by the compiler. Furthermore, also the overhead which accompanies watching the address of data cash mistake by repeating with inspection phase and sukitsupingu phase, can decrease. Data cash mistake is found more than between sukitsupingu phase between inspection phase.
