NRDecSqrt64 and NRDecSqrt128 IP core units are DFP Square Root designs, offered in 64-bit and 128-bit versions. The unit computes the square root of a vector Operand. Inputs are encoded in Decimal Interchange Format.
The square root unit is based on the Newton-Raphson iterative¬† method. It computes the final result in 2 iterations for the 64-bit version and in 3 iterations for the 128-bit version. The product is fully compliant with the IEEE 754-2008 Standard.
