IWR6843: 液压例程的RADARDEMO_highAccuRangeProc_rangeEst函数有具体的说明吗?比较难理解。

Part Number: IWR6843

你好!

1.:\mmwave_industrial_toolbox_4_7_0\labs\level_sensing\68xx_high_accuracy里面RADARDEMO_hightAccuRangeProc_priv.c里面的函数RADARDEMO_highAccuRangeProc_rangeEst

有没有具体的详细说明或者流程文档参考?

2.另外该函数里面的_norm()具体是怎么运算的?

TMS320C6000 Optimizing Compiler文档只有这样的说明:

Returns the number of bits up to the first nonredundant sign bit of src。

在:j  = 30 - _norm(highAccuRangeHandle->fft1DSize);后面打断点,查看highAccuRangeHandle->fft1DSize为512,j=0?
