31.5.14 mips_vec_sub32
Description
Subtracts each element of indata2 from the corresponding element of indata1. The number of samples to be processed is given by the parameter N.
Mathematically,
outdata[n] = indata1[n] – indata2[n]

(
int32 *outdata,
int32 *indata1,
int32 *indata2,
int N
);
Argument
outdata: Output array of 32-bit fixed-point elements in Q31 format.
indata1: First input array with 32-bit fixed-point elements in Q31 format.
indata2: Second input array with 32-bit fixed-point elements in Q31 format.
N: Number of samples.
Return Value
None.
Remarks
- The pointers outdata, indata1, and indata2 must be aligned on 4-byte boundaries.
- N must be larger than or equal to 4 and a multiple of 4.
