Question Paper
Discuss Fixed Point and Floating Point number representation with suitable examples.
How is performance measurement performed for processor level design
Show the data flow in different registers used in shift and add multiplication hardware for multiplying 13 and 12.
What types of instructions should be included in a general purpose processor's instruction set? Categorise them.
What is CISC? Explain its characteristics.
With a suitable diagram, explain the addition of two floating point numbers with the help of pipeline process.
4. Draw a space-time diagram for a six-segment pipelining showing the time it takes to process eight tasks. A non-pipeline system takes 50 ns to process a task. The same task can be produced in a six-segment pipeline with a clock cycle of 10 ns. Determine the speed-up ratio of the pipeline for 100 tasks. What is the maximum speed-up that can be achieved?
Explain the function of cache memory. How is it implemented?
How can virtual memory offer more memory than is really present in the primary memory to the software developer?
What do you mean by 'locality of reference' How many 128 x 8 RAM chips are needed to provide a memory capacity of 1024 bytes?
Explain the concept behind the address translation or address mapping.
A direct mapped cache has the following parameters
Cache size K words
Blocksize =128 words
Main memory size =64 K words
Specify the number of bits in TAG, BLOCK and WORD in main memory.
What are the various modes of data transfer between CPU and I/O devices?
What is the need of I/O controller?
Explain bus arbitration· using Polling works with necessary diagram. What is the advantage of Polling works over Daisy chaining?
9. With a neat block diagram, explain how DMA controller is initiated for DMA data transfer.
10. Write short notes on any two of the following:
Pipeline Processing
Associative Memory
Isolated versus Memory Mapped I/O
