Help me implement some DSP concepts in VHDL

[Padfoot3]

Hello,
Can anyone tell me how to go about implementing this equation in VHDL:
y = a0*x0+a1*x1+a2*x2+...
where a0,a1 ... are constants

Do I have to read the values of x and a from a text file ? Or can I specify the values in the code itself?

Borh is possible. In a real design the xn would be derived from an input signal, I guess. Or are you talking about simulated signals?

You should firstly think of a suitable numeric format for signals and constants. The IEEE fixed point package is a convenient way-
