时间和一致性测试

分别测试了benchmark的时间(Cycles),及其执行的任务数(total number of tasks).

测试结果和问题

alpaca的cem.c时间和任务数都产生溢出. 除cem.c外,alpaca和latics的benchmark的执行流程一致.

[x] 下一步将调试修复alpaca的cem.c.逻辑上暂时还没发现问题.
[x] 以及时间计数Cycles溢出的问题

将MCLK的工作频率调整在8MHz（如果需要用到UART，相应地调整UART的参数，与频率对应），SMCLK，即计时器的驱动频率调整到1MHz，分频比保持不变，为64.

void clock_sys_init()
{
    CS_setDCOFreq(CS_DCORSEL_0, CS_DCOFSEL_6);                              // DCO in 8MHz
    CS_initClockSignal(CS_MCLK,   CS_DCOCLK_SELECT,   CS_CLOCK_DIVIDER_1);  // MCLK = DCO = 8MHz
    CS_initClockSignal(CS_SMCLK,  CS_DCOCLK_SELECT,   CS_CLOCK_DIVIDER_8);  // SMCLK = DCO/8 = 1MHz, x8 divided DCO
    CS_initClockSignal(CS_ACLK,   CS_VLOCLK_SELECT,   CS_CLOCK_DIVIDER_1);
    CS_turnOffLFXT();
}

这可以让时间测量的范围较之前再提升8倍（但是精度也会相应变为原来的1/8）。

另外，对于任务数溢出的问题，用float或者uin32_t即可。

备注

MCLK = 8MHz
需要把alpaca()和latics()分别测量.
- 如果连续测量,会出现以下问题,原因不明:

latics(错误点): current testbench: 0.Cycles: 242048.the total number of tasks: 0.
