Division using a logarithmic-exponential transform to form a short reciprocal

Two trees are used sequentially to calculate an approximation to 1/A, where 1/spl les/A<2. These trees calculate the logarithm and exponential, and the division (reciprocation) process can be described by 1/A=e/sup -ln/A/. For bit skip accuracy of six to 10, this logarithmic-exponential method uses significantly less hardware with respect to the scheme in Mandelbaum (1993), and the delays may be greater or less, depending on the method used and the minimum bit skip.<
