PROGRAMMING ASSIGNMENT WITH REPORT

UFCF93-30-1 CNS: Course Work 2 Specification, Feb 2021

This assignment is divided into two tasks. Tasks1 is a research survey report whereas Task2 is related to programming. The tasks are described as follows:

• The central computer at GCET maintains the records for each of its students. Each student is identified by a 6-digit registration number. Consider there are 500 students in total. Write a program that asks the student for six-digit registration number and finds the memory location assigned to its records. Please write a report on increasing use of solid-state memory devices in the modern computers. [Marks 30]

• 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:

1. Design FSM for the Figure 1 [Marks 10]
2. Simulate the Figure 1 using C.                                                             [Marks 15]
3. Write 400 words report on shift and rotate registers and their function in the computer network systems             [Marks 20]
4. Using a. & b. design FSM for 8-bit shift register and simulate it using C, that can multiply or divide the 8-bit number by 4.                                                    [Marks 25]

• Correct Terminology
• It should be phrased in third person
• References (must be peer reviewed journals and conferences)
• Citations Marks [0 -15]

1. The marks for the program can be given as:

• C code (Efficient logic, use of loops and conditional statements) and testing

Marks [0-10]

• Short description of code Marks [0-5]

2. The marks for Task 2 are distributed in the following table.
