METHOD FOR AVOIDING OVERFLOW OF MULTIPLICATION OF ROOTS-OF-UNITY BY USING OVERFLOW SAFE APPROXIMATED VALUES TABLE |
摘要 |
An apparatus including a processor, a computer readable storage medium, and a lookup memory. The computer readable storage medium generally contains computer executable instruction that when executed by the processor perform operations involving fixed point multiplication. The lookup memory generally stores values used in the fixed point multiplication. The values stored in the lookup memory are approximated based upon a predetermined value to prevent overflow in the fixed point multiplication. |
