The sequential and indeterminate behavior of an end-around-carry (EAC) adder is examined. This behavior is commonly overlooked in the literature. Design modifications to impose determinism are provided. These modifications also eliminate the troublesome negative zero found in the one's complement number system.
Index Terms:
End-around-carry (EAC) adder, negative zero, one's complement arithmetic.
