Carefully read each sentence in this question. You may agree/disagree with each sentence (consider each sentence separately) if you have a good justification for doing so (not in more than 2 lines for each sentence). “A daisy chaining technique could result in starvation.” “The received data is saved in contiguous memory regions in DMA transfer.” “The most difficult method of device identification is multiple interrupt lines.” “An interrupt request takes longer for the CPU to handle than a DMA request.” “The architecture of InfiniBand operation is layered.”
Question 5 Multiple Choice: We have been assigned the task of selecting an interface language for a disk controller that must count disk reads. In particular, the controller must count how many reads have occurred since the last write to the disk and confirm that the count of reads does not exceed 1,000,000. Two proposals have been made. Method C uses C++ while Method R uses regular expressions. Then I would use Method C because Method R would translate into a finite automaton with at least 1,000,000 states. I cannot use Method C because it is not able to keep track of the count of reads. I would use Method C because Method R cannot keep track of the count of reads. I cannot use Method R because regular expressions cannot represent integers.

Question 4: There is an application that requires the hardware: an Intel 8031, a Program ROM of 8Kx8, a Data ROM of 4Kx8 for look-up tables, TWO Data RAMs of 8Kx8. The memory map of the design should be: Program ROM should start at address 0000μ. Then, the Data ROM should come above the Program ROM. Finally the Data RAMs must go to the top of the memory map. There should be no gaps between the memory addresses of the external ROMs or RAMS. A. Using logic gates, draw the pin connections of the design. Label your diagram fully. B. Calculate the address space of the ROMs and RAMs of your design. C. Show the design's address space on a memory map, starting with 0000μ at the bottom and FFFFH at the top.

3. An external event is sensed using polling with period P. It takes 100 cycles to processthe event. Processor frequency is 48 MHz. Before starting a new period, the previouspolling task should have finished. The relative deadline for processing an event is 10μs.(a) Determine the range of feasible polling periods? (b) Suppose now that an unrelated interrupt may occur and the interrupt has higher priority than the code for processing the polling event. Including all overhead, it takes 40 cycles to process the interrupt. The minimum time between two subsequent interrupts is T. Suppose that T is larger than 140 cycles. Determine the range of feasible polling periods.

A disk has a capacity of two tera-byte size. Say the file system uses a multi-level inode structure for locating the data blocks of afile.The inode stores pointers to data blocks, including a single indirect block, a double indirect block, and several direct blocks in the 64 B of available space.Now, it is given that the disk has a block size of 512 B. The maximum file size that can be stored in such a file system in MB (round off upto 2 decimal places).
