}
else
{
adapt = 2;
}
}
2、改編后的代碼：
adapt = (ltpg>LTP_GAIN_THR1) + (ltpg>LTP_GAIN_THR2);
（二）
1、源代碼：
if (adapt == 0)
{
if (filt>5443)
{
result = 0;
}
else
{
if (filt < 0)
{
result = 16384;
}
else
{
filt = _sshl (filt, 18)>>16; // Q15
result = _ssub (16384, _smpy(24660, filt)>>16);
}
}
}
else
{
result = 0;
}
2、改編后的代碼：
filt1 = _sshl (filt, 18)>>16;
tmp = _smpy(24660, filt1)>>16;
result = _ssub(16384, tmp * (filt>=0));
result = result * (!((adapt!=0)||(filt>5443)));
（三）
1、源代碼：
static Word16 saturate(Word32 L_var1)
{
Word16 swOut;
if (L_var1 > SW_MAX)
{
swOut = SW_MAX;
giOverflow = 1;
}
else if (L_var1 < SW_MIN)
{
swOut = SW_MIN;
giOverflow = 1;
}
else
swOut = (Word16) L_var1; /* automatic type conversion */
return (swOut);
}
2、改編后的代碼：
static inli
