In digital electronics and modern computer hardware, a flip-flop is sequential digital circuit used as a basic memory element. It has two stable states and can be used to store state information. One of its states represents ‘1’ while the other represents ‘0’. The most common types of flip-flops are SR-flip-flop, JK-flip-flop, and D flip-flop. When used in a finite-state machine, the output and next state depend not only on its current input, but also on its current state (and hence, previous inputs).

Figure 1 D-Flip-flop with clock pulse (CP)
Figure 1 shows a D flip-flop with clock pulse (CP). D is directly passed from stage1 to stage 2 through NAND gate and passed as inverted through gate 5 and gate 4. The input D is always sampled when the system CP is 1.
Considering the memory element in Figure 1, perform the following tasks:
- Design FSM for the Figure 1
- Simulate the Figure 1 using C.
- Write 400 words report on shift and rotate registers and their function in the
computer network systems - Using a. & b. design FSM for 3-bit shift register and simulate it using C, that can multiply or divide the 3-bit number by 2.
