1.4.2.8 mchp_correlate_q31()

void mchp_correlate_q31 (const q31_t * pSrcA, uint32_t srcALen, const q31_t * pSrcB, uint32_t srcBLen, q31_t * pDst)

Correlation of Q31 sequences.

Parameters:
in	pSrcA	points to the first input sequence.
in	srcALen	length of the first input sequence.
in	pSrcB	points to the second input sequence.
in	srcBLen	length of the second input sequence.
out	pDst	points to the block of output data Length 2 * max(srcALen, srcBLen) - 1.

Note:

Implementation reverses pSrcB in-place before calling convolution. The const qualifier matches the ARM CMSIS-DSP API contract; callers should not rely on pSrcB being unmodified.
