Square Root Implementation in LabvIEW FPGA
Print
This example shows one method for calculating a square root in LabVIEW FPGA. The VI finds the closest integer to the actual square root value and the remainder (error). It accepts a 32 bit unsigned integer and takes 18 clock cycles to execute. A slightly simpler version is also included which returns the next lower integer to the actual square root value. This implementation does not use two multipliers as the full version does.
This implementation is based on the following published article:
