1. Problem Specification:
Design a circuit that forms the sum of all the 2's complements integers stored in a linked-list structure starting at memory address 0. The linked-list structure is shown below:

All integers and pointers are 8-bit. The link-list is stored in a memory block with an 8-bit address port and 8-bit data port, as shown below. The pointer from the last element in the list is 0.

START
Resets to head of list and starts addition process.
DONE
Signals completion of addition.
R
Bus which hold the final result when DONE = 1.
