Abstract :
The leading zero anticipator (LZA) is a vital block in fast floating point addition and fused multiply-add (FMA) operations. So far, there is only one decimal LZA proposed in research literature. This paper introduces two decimal LZA designs, then a comparison between the three designs, the two proposed here and the previous proposed one, is performed.
