| 8. | The algorithm and its implementation of the leading zero anticipation are very vital for the performance of a high - speed floating - point adder in today s state of art microprocessor design . unfortunately , in predicting " shift amount " by a conventional lza design , the result could be off by one position . this paper presents a novel parallel error detection algorithm for a general - case lza
目前国际上已有很多算法对前导0预测算法进行了研究，但是出于设计方法和延迟等方面的限制，大部分前导0预测算法都为非精确算法，其预测结果可能与真实加法结果中前导0的个数产生一位的误差，这个误差需要在浮点加法的后规格化过程中进行修正，因此反过来又增加了浮点加减算法的关键路径延迟。 |
