Abstract: An address boundary detector is disclosed that functions with an arithmetic logic unit (ALU) in a computer processor while the ALU generates addresses by adding an offset or displacement to a base address. The detector monitors bits of addresses to determine whether a data item can be completely stored within the same block or page of memory as that addressed by the base address from which it was derived.
