It enables
you to extract two 8-bit values from an operand and sign-extend
them to 16 bits each.
Syntax
unsigned int __sxtb16(unsigned int val
Where valval
Return value
The __sxtb16 intrinsic returns the 8-bit
values sign-extended to 16-bit values.
Examples
unsigned int sign_extend(unsigned int val)
{
unsigned int res;
res = __sxtb16(val1,val2); /* res[15:0] = SignExtended(val[7:0]
res[31:16] = SignExtended(val[23:16]
*/
return res;
}
