Abstract
A processor capable of efficiently evaluating constant powers of an operand such as the reciprocal and reciprocal square root is disclosed. The processor comprises a multiplier that is configured to perform iterative multiplication operations to evaluate constant powers of an operand such as the reciprocal and reciprocal square root. Intermediate products that are formed may be rounded and normalized in two paths, one assuming an overflow will occur, and then compressed and stored for use in the next iteration. The processor comprises a multiplier capable of performing signed and unsigned scalar and vector multiplication is disclosed. The multiplier may performing rounded by adding a rounding constant.
