Honored ContributorAdding MSB of the truncated part has the same effect as what I'm doing. Yes you do not need that long of an adder as I did, I just was showing it for clarity. If you are using the MSB of the truncated part you need an if statement or an adder with a non constant however.
XXXX_XXXX_XXXX_XXXX truncate to 6+1 bit XXXX_XXX +0000_001 Throw away the LSB Versus XXXX_XXXX_XXXX_XXXX truncate 6 MSBs XXXX_XX +0000_0(MSB of truncated part) Use the whole result. Don't know which one would optimize better. Either one is probably about the same. /Boris
