The following figure illustrates a bit-serial adder circuit. The operation of the system is described below 1. The two operand values are loaded into the two registers \( \mathrm{R} 1 \) and \( \mathrm{R} 2 \). 2. The controller receives start signal to launch the operation 3. The controller perform bit-wise addition, sequentially from bit 0 until bit \( n \). 4. After every addition, the result is stored in bit \( n \) of R1. Register shift is achieved with sh \( =1 \). 5. The controller checks if all bits of \( A \) have been processed 6. If true, the controller sets Done to 1 and return to it's initial state, waiting for the next input start 7. Else the controller continues to check the bits of \( A \) 1. The figure of the circuit is incomplete: add the missing components, define the function of the combination block make the right connections (3 pts) 2. Provide the design of the controller as Moore diagram ( 6 pts) 3. Convert your diagram into a Moore state transition table (3 pts) 4. Design your controller as microprogrammed unit (4 pts)
