标 题: 高人指点profiler数据的含义
发信站: BBS 水木清华站 (Thu Jun 6 23:44:01 2002)
用ccs设置了两个profiler的绿色的断点后就开始run，run了一会停下来
在statitics里面出了两行数据：
location count max min average total
XXXXX XX XX XX XXX XX
***** ** ** ** *** **
这些数据的含义是什么呀（主要是想知道它们和那两个断点的关系）
谢谢大虾.....

在CCS的Help上有相关的介绍！虽说是E文，但是不是很难！
Good Lucky！
The Profile Statistics window displays the results for each profile point.
Each point displays the number of times it has been hit and the statistics
on the number of cycles or other events that have elapsed since the previous
profile point was hit. The
statistics include the minimum, maximum, total, and average number of cycles.
The Profile Statistics window updates every time a profile point is hit,
but too many window updates can slow down the profiling performance.
There are two ways to reduce the number of times the window updates:
connect the window to a Probe Point, or
open and close the window as needed. When you connect the Profile Statistics
window to a Probe Point, it only updates when the Probe Point is hit.
Therefore, you have control over when in your application the Profile Statisticss window updates. This
window only displays profiler results and is not needed to collect profiler
statistics; therefore, it does not need to be open all the time.

^^^这个就是平均周期数，设为a

又你知道该函数每秒钟执行的次数，设为b，那么，该函数的运算量m为：
m=a*b/10^6(mips)
