Abstract :
Current pipelinable dividers require very large lookup tables. We propose a cost-effective pipelinable divider that uses a modified Taylor-series expansion and has a smaller lookup table than other pipelinable dividers. The proposed divider requires about 27 percent less area than the pipelinable divider based on normal Taylor-series expansion in single precision.
