Assignment No. 05
CS501: Advanced Computer Architecture
Total Marks: 20
Due Date: 03-07-13
Please read the following instructions carefully before assignment submission.
It should be clear that your assignment will not get any credit if:
The objective of this assignment is:
Suppose we have a benchmark that executes in 100 seconds of elapsed time, where 90 seconds is CPU time and the rest is I/O (Input/output) time. If CPU time improves by 50% per year for the next five years but I/O time doesn’t improve, how much faster will our program run at the end of five years?
You are required to calculate the CPU improved performance and improved elapsed time.
Question No 2: (4 marks)
Consider a 20 MIPS (Microprocessor without Interlocked Pipeline Stages) processor with several input devices attached to it, each running at 1000 characters per second. Assume that it takes 17 instructions to handle an interrupt. If the hardware interrupt response takes 1msec, what is the maximum number of devices that can be handled simultaneously?
NOTE: Theoretical answer will not be considered
Question No 3: (6 Marks)
If we want the lowest latency for an I/O operation to a single I/O device; while in terms of lowest impact on processor utilization from a single I/O device then what will be the orders/arrangements of Interrupt driven, DMA(Direct Memory Access) and polling in both scenarios? Explain reasons.
NOTE: Give answer within 3-5 lines. Otherwise answer will not be considered.
GOOD LUCK J
how much faster our program run at the end of five year?
chavlay zayada marti hooo....
dosro ko tens krny k liyaaa.....
very bad sir faiz khan apki zuban pak ko bat pak krny ki tmeez pak nai hy
Question no 2 is same as handouts
the question # 2 given in handouts and the question given in our assignment is same !! BFSS sister is right.
BFSS plzzz tell me the rite answerz!!!
which question ?
i think answer is correct in handout, plz compare ur statement of q no 2 in ur assignment and handout. ok
us nay bola theorey nai chalnay wali :-(
