Hi,
so the math is clear so far (I hope).
Please provide clear descriptions, like
* one table row shows the contents (8 bytes, starting from left side) of one address (0...3)
(often bit order / byte order is descending, thus the other way round than in your example)
so the system should be (like may systems)
INPUT --> CALCULATE --> OUTPUT
you need to clarify:
* How do you access the input and the output?
* What if the sum of two numbers is an odd value?
* What is your system clock freuquency?
* What is the memory timing?
* What is the calculation timing?
