31.5.11 mips_vec_mulc16
Description
Multiplies each Q15 element of indata by the Q15 constant c and stores the results to outdata. The number of samples to be processed is given by the parameter N.
Mathematically,
outdata[n] = indata1[n] x c

(
int16 *outdata,
int16 *indata,
int16 c,
int N
);
Argument
outdata: Output array of 16-bit fixed-point elements in Q15 format.
indata: Input array with 16-bit fixed-point elements in Q15 format.
c: 16-bit fixed-point constant.
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.
