hi,

i need to write a code for finding the square root of the number in verilog and code must be sinthesizable in FPGA . Did anybody suggest me what is the best methode to find square root of a number (fastest methode) . THE NUMBER SHOULD BE LARGE. what about cordaic algoritham is it fast???
is there any readymaid code for this???
is it possible to find square root including fractional part .

eg: sqrt of 8 =2.83 like this .plz give me some guidence.
thanks & regards

Hi,
Are you have plan to use IEEE-754 floating point format? Your input format is not clear.

Re: square root of a number..............

whether you want floating point or integer, xilinx and altera provide cores to do such a thing already.
 

In his previous thread, dipin was dealing with the Xilinx ddivider core. Presumed, this is also a Xilinx related problem, it seems a small step to review the list of available math functions from Xilinx, and ask specific questions if necessary.

Or if it's a homework problem demanding the implementation of a squareroot algorithm from the scratch, to specify the input and output formats and other features (optimization speed versus area, sequential solution possible?) precisely.
