Abstract
A circuit which concurrently performs bit shifting for floating point arithmetic and sticky bit determination. An input data operand is presented to the circuit along with a control signal which determines the number of digit positions to be shifted. While shifting of bits occurs to provide a shifted output operand, detection of bits which are shifted off from the output operand for the presence of sticky bits occurs. A shifted output operand and a sticky bit detect signal are provided substantially concurrently. An efficient layout of the circuit significantly minimizes the area required to implement both functions.
