Abstract:
A method for computing the alignment sticky bit in floating-point operations is provided. The method includes computing a pre-computed sticky bit. A significand is aligned based on an alignment counter. A shifter sticky OR is computed. The alignment sticky bit is computed based on the pre-computed sticky bit by ORing the pre-computed sticky bit and the shifter sticky OR when the alignment counter comprises a value greater than or equal to a predefined value.
