Function MLIB_MulSat_F16<br />

4.154.8 Code Example<br />

#include "mlib.h"<br />

tFrac16 f16In1;<br />

tFrac16 f16In2;<br />

tFrac32 f32Out;<br />

void main(void)<br />

{<br />

// first input = 0.8<br />

f16In1 = FRAC16 (0.8);<br />

}<br />

// second input = 0.75<br />

f16In2 = FRAC16 (0.75);<br />

// output should be 0x4ccccccc = FRAC32(0.6)<br />

f32Out = MLIB_MulSat_F32F16F16(f16In1,f16In2);<br />

// output should be 0x4ccccccc = FRAC32(0.6)<br />

f32Out = MLIB_MulSat (f32In1,f32In2,F32F16f16);<br />
