<Li> Overflow, which indicates the result of an arithmetic operation has exceeded the numeric range of Y . </Li> <Li> Parity, which indicates whether an even or odd number of bits in Y are logic one . </Li> <P> At the end of each ALU operation, the status output signals are usually stored in external registers to make them available for future ALU operations (e.g., to implement multiple - precision arithmetic) or for controlling conditional branching . The collection of bit registers that store the status outputs are often treated as a single, multi-bit register, which is referred to as the "status register" or "condition code register". </P> <P> The status inputs allow additional information to be made available to the ALU when performing an operation . Typically, this is a single "carry - in" bit that is the stored carry - out from a previous ALU operation . </P>

Which of the following is the expansion of alu
