4-Bit Magnitude Comparator
COMPM4 is a 4-bit, magnitude comparator that compares two positive binary-weighted words A3 – A0 and B3 – B0, where A3 and B3 are the most significant bits. The greater-than output (GT) is High when A>B, and the less-than output (LT) is High when A<B. When the two words are equal, both GT and LT are Low. Equality can be measured with this macro by comparing both outputs with a NOR gate.
