It enables
you to extract two 8-bit values from one operand, zero-extend them
to 16 bits each, and add the results to two 16-bit values from another
operand.
Syntax
unsigned int __uxtab16(unsigned int val1val2
Where val2val2
Return value
The __uxtab16 intrinsic returns the 8-bit
values in val2val1
Examples
unsigned int extend_add(unsigned int val1, unsigned int val2)
{
unsigned int res;
res = __uxtab16(val1,val2); /* res[15:0] = ZeroExt(val2[7:0] to 16 bits)
+ val1[15:0]
res[31:16] = ZeroExt(val2[31:16] to 16 bits)
+ val1[31:16]
*/
return res;
}
