Abstract
An integrated circuit including a circuit for determining shift overflow in a binary digital circuit having an n-bit shift data and an m-bit shift amount. The device has a logic array for producing an n-bit output from the m-bit shift amount; a conversion circuit for selectively converting the sign of an n-bit shift data; and a combination of OR and AND logical gates for logically combining the selectively converted n-bit shift data and the n-bit output producing an overflow output.
