APPARATUS AND METHODS FOR HARDWARE-EFFICIENT UNBIASED ROUNDING

摘要

A system and method for unbiased rounding away from, or toward, zero comprising apparatus for truncating N bits from an original M bit input number thereby to provide a M - N bit number, and apparatus for adding the equivalent value of '½' to the M - N bit number unless the input number is negative, or positive, respectively, and the N truncated bits represent exactly ½.
