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?
已经帮您升级到英文论坛,请关注:

你好!
查看文档中关于norm的说明,norm(highAccuRangeHandle->fft1DSize) = norm(512)应该是等于9,那么 j = 30 - _norm(highAccuRangeHandle->fft1DSize)应该是21,不是等于1,所以想问一下,为什么程序打断点的值是1?英文论坛的回复说是奇偶校验?如果是奇偶校验,那么norm(highAccuRangeHandle->fft1DSize的值应该是0,或者1?那么 j值应该是30或者29?
