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.
