CS501 3 Advanced Computer Architecture Assignment solution fall december 2011

Question No.1:

Let us consider an I/O bus that can transfer 6 bytes of data in one bus cycle. presume that a designer is considering to attach the following two components to this bus:

Hard drive with a transfer rate of 80 M bytes/sec

Video card with a transfer rate of 200 M bytes/sec

What will be the implications if both of these components need to work simultaneously?

(The maximum frequency of the bus is 30 MHz)

Solution:

 The maximum frequency of the bus is 30 MHz. This means that the maximum bandwidth of this bus is 30 x 6 = 180 Mbytes/sec. Now, the demand for bandwidth from these two components will be 80 + 200 =280 Mbytes/sec which is more than the 180 Mbytes/sec that the bus can provide.

Thus, if the designer uses these two components with this bus, one or both of these components will be operating at reduced bandwidth.

Question No.2:

If a bus requires 15 nsec for bus requests, 10 nsec for arbitration and the average time to complete an operation is 10 nsec after the access to the bus has been granted, is it possible for such a bus to perform 40 million IOPS?

Solution:

For 40 million IOPS, the average time for each IOP is 1 / (40 x 10⁶) =25 nsec. Given the

information about the bus, the sum of the three times is 10 + 10 + 15 = 35 nsec for a

complete I/O operation. This means that the bus can perform a maximum of 1 / ( 35 x 10^-9 ) = 28.6 million IOPS.

Thus, it will not be able to perform 40 million IOPS.

CS402 theory of automata quizes

1. Two languages are said to belong to same class if they C when they run over an FA, that state  (May befinal State or not).
2. One language can have ……… CFG(s) (At least one)
3. If an FA has N state then it must accept the word of length (n+1)
4. In pumping lemma theorem (x y^n z) the range of n is (1,2,3,4,………)
5. For a non regular language there exist …… FA (NO)
6. If the intersection of two regular languages is regular then the complement of the intersection of these twolanguages is also regular (True)
7. According to Myhill Nerode theorem, if L generates finite no. of classes then L is.......(Regular)
8. The language generated by the CFG is called the language ……by the CFG (Produced) 
9. If L1 and L2 are regular languages then which statement is NOT true? (L1/L2 is always regular)
10. The values of input (say a & b) does not remain same in one cycle due to (clock pulse)
11. The reverse of the string sbfsbb over { sb, f, b } (bsbfsb)
12. In CFG, the symbols that cannot be replaced by anything are called Terminals
13. a^n b^n generates the ………… language (Non regular languages)
14. The production S --> SS | a | b | ^ can be expressed by RE (a+b)+
Any word generated by given CFG can also be expressed by (Syntax tree or Generation
tree or Derivation tree as well)
15. Set of all palindromes over {a,b}is regular (false)
16. The grammatical rules which involves meaning of words are called: (semantic)
17. An FA has same initial and final state, then it means that it has no final state. (false)
18. The same non terminals can be written in single line if they have more than one..........(Productions)
19. In pref(Q in R) Q is …… to (than) R (Q is not equal to R)
20. The complement of a regular language is also a regular (True)
21. There is at least one production that has one........on its left side. (None Terminal)
22. For language L defined over {a, b},then L partitions {a, b}* into …… classes (Distinct) 

cs602 3 Computer Graphics assignment solution fall december 2011

Question                                      20 marks

In the handouts of CS602 – Computer Graphics many examples are given in which GRAPHICS.H Header file is used. If you compile the given code in Dev-C++ IDE / Compiler the errors are reported because the given code is using GRAPHICS.H which is originally provided by Borland (www.borland.com). But there are ways to compile that code on Dev-C++. For this purpose you can consult the following tutorials:

1. http://vulms.vu.edu.pk/Courses/CS602/Downloads/DevCppTutorialGraphics_h.pdf
2. http://www.uniqueness-template.com/devcpp/

You are required to compile the given code after following the above tutorial and submit the following files in zip archive:

1. Dev-C++ Project File (e.g. Project1.dev)
2. C++ Source (e.g. main.cpp)
3. O/Object File (mian.o)
4. Makefile.win
5. Executable File (e.g. Project1.exe) it is much necessary as a proof that you have successfully compiled the code.
6. Microsoft Word File explaining the code.

Solution

download the "graphics.h" and "libbgi.a" from the following link.

http://www.cs.colorado.edu/~main/bgi/dev-c++/
or
http://www.uniqueness-template.com/devcpp/

copy "graphics.h" into "C:\Dev-Cpp\include\"

and

"libbgi.a" into "C:\Dev-Cpp\lib\".

open devcpp and start new project. choose windows application from new project dialog.

create new source file and paste the below code into it.
