c) How do cache memories improve the performance of the computer and how is the performance of the cache determined? Explain fully associative mapping , Direct mapping and 2 way Set associative mapping techniques for cache memory in a computer system that has 24-bit logical address, with cache block size of 16 bytes and cache memory of 4 kilobytes. 5. a) Compare strobe and handshaking method of asynchronous transfer initiated by the source. b) What are the different methods of I/O transfer and explain how is data transfer is done using DMA. c) i) Based on Flynn’s classification which type of system uses pipelining to implemen t parallel processing? Why? Explain how instruction pipelining is implemented. With suitable examples discuss the problems associated with instruction pipelining and the methods to handle them. (OR) ii) Compare the various methods for performing a data transfer between input- output devices and memory. It is necessary to transfer 512 words from memory starting from address 4700 to a magnetic disk. The transfer is done by means of a DMA. Give the step by step account of the actions taken during the transfer. /END/ FD/JU

    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.
