CCS中使用DSP定时器的计时程序，可以精确计算某一段程序的执行时间

#include <csl_timer.h>TIMER_Handle hTimer0;TIMER_Config TimerConfig ={TIMER_CTL_RMK(TIMER_CTL_SPND_EMUSTOP,TIMER_CTL_INVINP_NO,TIMER_CTL_CLKSRC_CPUOVR8,//定时器的频率是CPU频率的1/8TIMER_CTL_CP_PULSE,TIMER_CTL_HLD_NO,//时钟有效TIMER_CTL_GO_NO,//时钟没有开启TIMER_CTL_PWID_TWO,TIMER_CTL_DATOUT_1,TIMER_CTL_INVOUT_YES,TIMER_CTL_FUNC_TOUT),0xffffffff,//定时器计数值，一旦达到该值就会产生中断，该计数值可以最大计数57秒不中断0x0//计数器初值};void Timer0_Cnt(){float timecnt,timeval;hTimer0 = TIMER_open(TIMER_DEV0,TIMER_OPEN_RESET);//打开定时器0，返回操作句柄TIMER_config(hTimer0,&TimerConfig);//使用配置结构体配置定时器0TIMER_start(hTimer0);//开始计数/***********此处为要计时的程序段***********/timecnt = TIMER_getCount(hTimer0);//获取定时器的计数值TIMER_pause(hTimer0);//停止计数timeval = (float)(timecnt*8/600000000);//将计数值转化为时间值printf("The time spended is %fs",timeval);//打印程序运行时间}
