1、XTime_GetTime()函数如何实现; 2、公式tUsed = ((tEnd-tCur)*1000000)/(COUNTS_PER_SECOND)的含义; 1、XTime_GetTime()的代码如下: /*** * * Get the time from the Cycle Counter Register. * * @param Pointer to the location to be updated with the time. * * @return None. * * @not...
一、API 头文件 “xtime_l.h” 函数XTime_GetTime(XTime * xtime),获取周期数 时钟频率宏 COUNTS_PER_SECOND 二、使用 #include "xtime_l.h"int main(){XTime tBegin, tEnd;unsigned int t_us;unsigned long long cycles;XTime_GetTime(&tBegin);/*do something*/XTime_GetTime(&tEnd);cycles = tEnd...
