请问DSPC674X的库函数支持互相关函数吗?



如题,查看了c674x的dsplib,发现只有自相关函数void DSPF_sp_autocor(float *restrict r, float *restrict x, const int nx, const int nr);

然后还有一个卷积函数void DSPF_sp_convol(const float *x, const float *h, float *restrict y, const short nh, const short ny);

看了下相关和卷积都是乘累加运算,想问下dsp库的相关函数是只有自相关吗?互相关是这个卷积函数吗?还是没有互相关函数?

请求帮忙解答!谢谢!
