31.5.2 mips_vec_abs32
Description
Computes the absolute value of each element of indata and stores it to outdata. The number of samples to be processed is given by the parameter N.
Mathematically,
outdata[n] = abs(indata[N])

dsplib_dsp.h
Prototype
void
mips_vec_abs32
(
int32 *outdata,
int32 *indata,
int N
);
Argument
outdata: Output array of 32-bit fixed-point elements in Q31 format.
indata: Input array with 32-bit fixed-point elements in Q31 format.
N: Number of samples.
Return Value
None.
Remarks
- The pointers outdata and indata must be aligned on 4-byte boundaries.
- N must be larger than or equal to 4 and a multiple of 4.
