fractional* VectorCorrelate (int numElems1, int numElems2, fractional* dstV,
fractional* srcV1, fractional* srcV2);
Arguments
Parameters Description
numElems1
Number of elements in the source one vector (N)
numElems2
Number of elements in the source two vector (M, with M ≤ N)
dstV
Pointer to the destination vector (of size N+M-1)
srcV1
Pointer to the source one vector
srcV2
Pointer to the source two vector
Returns
Pointer to the base address of the destination vector.
Remarks
The number of elements in the source two vector must be less than or equal to the number of
elements in the source one vector.
The destination vector must already exist, with exactly numElems1+numElems2-1 number of
elements.
This function can be self-applicable.
This function uses VectorConvolve.

Note :
1. The above-mentioned program word and cycle counts pertain solely to VectorCorrelate.
However, as this function inherently utilizes VectorConvolve, the respective counts for
VectorConvolve must also be considered.
2. In the description of VectorConvolve, the number of cycles reported includes four cycles
of C-function call overhead. Thus, the number of actual cycles from VectorConvolve to
add to VectorCorrelate is four less than whatever number is reported for a stand-alone
VectorConvolve.
System resource usage
The below system resource usages are excluded from those of the VectorConvolve function.
• W0…W7 - used, not restored
• REPEATinstruction(s) usage – None
2.3.5. VectorDotProduct
Description
VectorDotProduct computes the sum of the products between the corresponding elements of the
source one and source two vectors.
