Real number

Question

Hi I´m a begginer and

I´m trying to do the LMS algorithm in VHDL (least mean square), and i have to use real numbers... i have to use the function "IF" with them and some operations (* ,/, + ,-)...

Wich libraries i have to use?

How can the quartus II suport them?

thanks

Quartus is supporting float arithmetics with some ALTFPxx MegaFunctions. But they have to be instantiated as components and can't be inferred from operators in HDL code. I'm not aware of any synthesis tool, that is offering direct float support.
