Partial Question 12 Fill in multiple blanks. Consider the snapshot of this memory starting from the top cell at Address 1E1AH. 10011000 00010101 11011010 10100000 11000111 01010101 When performing a read of the 4th cell from the top (the first cell is at Address 1E1AH): 1) The Read Data input must be set to 110110101 2) The Write Data input must be set to 10011000 3) The Address bus must be set to 11000111 In response, the memory will output on the 00010101 bus the binary number 10100000 corresponding to the hexadecimal number 01010101 h. Answer 1:
Help me with these computer architecture questions, please. I need help with questions 3 and 4.
Please and thank you. 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.
Describe the role of encryption in securing data during transmission over the internet.
Let, in 8086 based system current SP value is FFFAh and the CS, IP and FL values are 7000h, 1000h and 1001h, respectively. Now, if at that instance an interrupt occurs, then show the stack increase and decrease scenario along with changes in SP values and stack contents.
(b) Read each sentence of this question carefully. You may agree/disagree with each sentence (treat each sentence independently) with proper reason (not in more than 2 lines for each sentence). “Daisy chaining scheme may cause starvation”. “In DMA transfer, the received data is stored at contiguous memory locations”. “Multiple interrupt line is the most difficult way of device identification”. “CPU requires more time to handle an interrupt request than a DMA request”. “InfiniBand operation has a layered approach architecture”.
If we take interrupt latency into consideration, how long does it take to switch between contexts, for instance?
The concepts of interrupt latency and context switching time are broken down into its constituent elements during the course of this article.
