Abstract
The present disclosure relates to an add and decode hardware logic circuit for adding two n bit inputs, A and B. A series of n logic stages are each configured to perform a first operation of propagating a result of a preceding stage on the condition that the sum of A[m] and B[m] is equal to 0, wherein 0<=m<n, perform a second operation of performing a bitwise left shift by 2of the result of the preceding stage on the condition that the sum of A[m] and B[m] is equal to 1, or perform a third operation of performing a bitwise left shift by 2of the result of the preceding stage on the condition that the sum of A[m] and B[m] is equal to 2. An output at the last stage provides a decoded sum of the inputs A and B.
