7. List the various modes of I/O transfer and explain how transfer between memory and I/O device take place directly, giving one example for each. 8. Illustrate the strobe pulse method and handshaking method of asynchronous data transfer using suitable diagrams. 9. Describe the essential features of CISC and RISC processors. State the advantage of overlapped register windows in RISC processors. 10. List different machine cycles involved a typical instruction cycle. Explain the four segment instruction pipeline with a flow-diagram and timing diagram. 11. Illustrate the implementation of an instruction pipeline. Consider the four instructions in the following program. Suppose that the first instruction starts from step1 in a 4 segment pipeline, specify what operations are performed in the four segments during step 4. Load R1 M[10] Add R2 R2+M[10] Inc R3 R3+1 Store M[20] R3 With suitable examples discuss the problems associated with instruction pipelining and the methods to handle them. 12. What is instruction pipelining? Explain various hazards and technique to resolve them.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
