For this project, I created code (in C++) to generate VHDL for a Dadda tree multiplier, VHDL for a Dadda tree squarer, and a GIF of the partial product reduction used in each.
You can use this link to a CGI program which will generate a GIF for you and send it to your browser window. - Temporarily unavailable.
