According to a presently preferred embodiment of the present invention, a method for processing a incoming signal comprising the steps of selecting from a first signal a first plurality of bits of signal information to be processed, selecting from a second signal a second plurality of bits of signal information to be processed, reading the first plurality of bits of signal information into contiguous memory space so as to form a first word, reading the second plurality of bits of signal information into contiguous memory space so as to form a second word, causing a first logical AND operation to be performed on the second word with a mask, causing a first logical OR operation between the first word and the complement of the mask, causing a first EXCLUSIVE OR operation between the first word and the complement of the second word, causing a second logical AND operation between the results of the first EXCLUSIVE OR operation and the complement of the mask, subtracting the results of the first logical AND operation from the results of the first logical OR operation, and causing a second EXCLUSIVE OR operation to be performed on said results of the first subtraction operation with the results of the second AND operation.
