Polynomial Evaluation

Hello, I'm totally new to VHDL and i'm trying to do a polynonamial evaluation. In particular I have a signed 16 bit value (x) and I want to obtain y=d*x^3+c*x^2+b*x+a. I have created a sig...

Instead of asking us if it works - how about testing it yourself and learning the tools?

I'm doing it Tricky. I'm using Quartus II with the university Program VWF. But I'm totally new also to it. I started with vhdl and testbench two days ago.. Also a little hint could give me the right direction.

@Kaz, I need only 16 bit at the final sum as I have a 16 bit dac so at the output of the polynomial I MUST have a 16 bit signal.

So as I have understood from your last post I do not need the leading zeros in the signals input of the sum and also at the output signal.. Am I right ?

Thank you for your time !
