31.5.3 mips_vec_add16

Description

Adds each element of indata1 to the corresponding element of indata2. The number of samples to be processed is given by the parameter N.

Mathematically,

outdata[n] = indata1[n]+indata2[n]

Include

dsplib_dsp.h

Prototype

void
mips_vec_add16
(
       int16 *outdata,
       int16 *indata1,
       int16 *indata2,
       int N
);

Argument

outdata: Output array of 16-bit fixed-point elements in Q15 format.

indata1: First input array with 16-bit fixed-point elements in Q15 format.

indata2: Second input array with 16-bit fixed-point elements in Q15 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.
