ABSTRACT:
The expression A+sign(A), where A is a signed binary integer represented in 2's complement form, sign(A) is equal to one when A is greater than zero, sign(A) is equal to zero when A is zero, and sign(A) is equal to negative one when A is less than zero, is calculated by bit-complementingA, bit-complementing(A+1) when A is less than zero, bit-complementing A when A is equal to zero, bit-complementing(A-1) when A is greater than zero and odd, and bit-complementingall bits except a least significant bit of A when A is greater than zero and even. Zero detect for A is provided by determining whether a first carry-out bit from (A+0) and a second carry-out bit from (A+1) have different logical values. In this manner, A+sign(A) can be calculated by a general purpose computer in a single instruction cycle.
