Square Root operation has found its prominence in many digital signal processing but it is very elusive to implement on FPGA due to its complicated computations. Many iterative algorithms which include restoring and non-restoring algorithms, SRT were proposed. Most of them implement with slow or large components which are less suitable for real-time applications than the addition or multiply components. This paper deals with the novel algorithm of square root computation of double precision floating point division. Verilog Code is written and implemented on Virtex-5 FPGA series.
