I don't mean to heart your moral - but if you don't know any VHDL you have A LOT of learning ahead.
As a starting step:
1. Make sure you're VERY familiar with how digital logic works (MUX, Flip Flop, Gates, etc...).
2. Learn the basic syntax rules of VHDL (what is an entity, architecture, signal, etc...).
3. Practice writing the simple digital logic from #1 with the knowledge you gained from #2.
4, During #3 Post very specific questions on this forum.
Good Luck!
