The proposed approach enables parallel execution of conventional lza and its error detection , so that the error - indication signal can be generated earlier in the stage of normalization , thus reducing the critical path and improving overall performance . the circuit implementation of this algorithm also shows its advantages of area and power compared with other previous work 本文提出了一種新型的基于錯(cuò)誤糾正機(jī)制的前導(dǎo)0預(yù)測(cè)算法,該算法在傳統(tǒng)非精確算法的基礎(chǔ)上增加了對(duì)其結(jié)果出錯(cuò)時(shí)的預(yù)判機(jī)制和規(guī)格化過(guò)程中的實(shí)時(shí)糾正機(jī)制,從而實(shí)現(xiàn)了尾數(shù)和規(guī)格化時(shí)的精確移位,降低了浮點(diǎn)加減運(yùn)算的關(guān)鍵路徑延遲。
