How to implement a code that uses floating-point?

Hello, How should I do to implement in VHDL, a code that calculates the following equation: u(k) = 622,5u(k-1) + 0,6279u(k-2) + 651,2e(k) + 0,000814e(k-1) - 651,2e(k-2). I am a beginner in VHDL and d...

1. You will need to use the floating point IP cores. Have a read of the user guides: http://www.altera.co.uk/literature/ug/ug_altfp_mfug.pdf

2. It will be a std_logic_vector. THe IP cores do the work, you just wire them together.

No nios needed, a floating point calculation is perfectly usable. But expect the resource usage and latency to be quite large (probably >100 clk cycles of latency).
