PART- B
1. Explain in detail about memory Technologies
2. Expain in detail about memory Hierarchy with neat diagram
3. Describe the basic operations of cache in detail with diagram
4. Discuss the various mapping schemes used in cache design(10)
A byte addressable computer has a small data cache capable of holding eight 32-bit words. Each cache block contains 132-bit word. When a given program is executed, the processor reads data from the following sequence of hex addresses – 200, 204, 208, 20C, 2F4, 2F0, 200, 204,218, 21C, 24C, 2F4. The pattern is repeated four times. Assuming that the cache is initially empty, show the contents of the cache at the end of each pass, and compute the hit rate for a direct mapped cache. (6)
5. Discuss the methods used to measure and improve the performance of the cache.
6. Explain the virtual memory address translation and TLB withnecessary diagram.
7. Draw the typical block diagram of a DMA controller and explain how it is used for direct data transfer between memory and peripherals.
8. Explain in detail about interrupts with diagram
9. Describe in detail about programmedInput/Output with neat diagram
10.Explain in detail about I/O processor.
