I don't know if this question is a good question to get answers or not but I am trying to honestly explain my situation.
I am studying 8085 microprocessor, so I am stumbled upon address decoding circuits. As I was looking over past year questions, I saw many questions like the one I asked above are being asked in exams.
Then, I started to read books and pdfs all over the internet and knew the uses of address decoding, and other basic concepts such as memory mapped i/0...etc
Now, my confusions are
1) How to find the ending address for these 2 devices?
2) How to design a proper circuit for it?
This may be too broad, but I believe that many students are facing similar problems. Though this is not the place for homework solving but due to lack of good materials around the web, I am here and I am optimistic to get a complete solution.
