ABSTRACT:
A code conversion circuit comprising logic for converting an n-bit binary number having a sign bit in two's complement code to sign-magnitude code is provided where n is an integer. The logic identifies whether or not the binary number is positive or negative. Regardless of polarity, the sign bit and least significant bit are directly outputted. If the binary number is positive, all bits are outputted with unchanged logic states. If the binary number is negative, the least significant bit of the n magnitude bits which has a logic one value is identified. The remaining n magnitude bits of higher significance are inverted and outputted with the other magnitude bits.
