g Sir Tariq..?

Today My CS501 final term paper Muhammad Shahroz Munir
38 MCQ from Past Paper Waqar Siddhu files ,Moazz file and zain nasar file
1 mcqs
powerpc 601 kis ki exmple ha

superscalar processors Ans ye paka aye g sab ko

Question 1.
Calculate time to read 64 KB (128 sectors) for the following disk parameters.
–180 GB, 3.5 inch disk
–12 platters, 24 surfaces
–7,200 RPM; (4 ms avg. latency)
–6 ms avg. seek (r/w)
–64 to 35 MB/s (internal)
–0.1 ms controller time
Solution
Disk latency = average seek time + average rotational delay + transfer time +
= 6 ms + 0.5 x 1/(7200 RPM) /(60000ms/M)) + 64 KB / (64 MB/s) + 0.1 ms
= 6 + 4.2 + 1.0 + 0.1 ms = 11.3 ms
question 2:
Recode the integer 485 according to Booth procedure.
Solution
Original number:
00111100101=256+128+64+32+4+1=485
Recoded Number:
_ _ _
01000101111=+512-32+8-4+2-1=485
Question 3
Asynchronous I/O and Synchronous I/O in operating system
In order to improve the I/O performance, parallelism is used.
For this, two approaches are available:
• Synchronous I/O
• Asynchronous I/O
Synchronous I/O
In this approach, operating system requests data and switches to another process. Until
the desire data arrived. Then the operating system switches back to the requesting
process.
Asynchronous I/O
This model is of the process to continue after making a request and it is not blocked until
it tries to read requested data.
Question 4:
Consider a 64KB direct-mapped cache with a line length of 32 bytes.
a. Determine the number of bits in the address that refer to the byte within a cache
line.
b. Determine the number of bits in the address required to select the cache line.
Solution

n=log2 of number of bytes in line
m=log2 of number of lines in cache
a. For the given cache, the number of bits in the address to determine the byte
within the line= n = log232 = 5
b. There are 64K/32= 2048 lines in the given cache. The number of bits required to
select the required line = m =log22048 = 11

Hence n=5 and m=11 for this example.
Question: 5
that we use the term ‘memory space’ instead of memory,
because not all the memory space has to be filled with memory chips for a particular
implementation, but it is still a resource available to the programmer.
Solution:
The Concept of Instruction Set Architecture (ISA)
Now that we have an understanding of some of the relevant key terms, we revert to the
assembly language programmer’s perception of the computer. The programmer’s view is
limited to the set of all the assembly instructions or commands that can the particular
computer at hand execute understood/, in addition to the resources that these instructions
may help manage. These resources include the memory space and the entire programmer
accessible registers. Note that we use the term ‘memory space’ instead of memory,
because not all the memory space has to be filled with memory chips for a particular
implementation, but it is still a resource available to the programmer.
This set of instructions or operations and the resources together form the instruction set
architecture (ISA). It is the ISA, which serves as an interface between the program and
the functional units of a computer, i.e., through which, the computer’s resources, are
accessed and controlled.
Question 6
where TCP/IP used ?
Question 7
wright down the two main function of branch instruction ?
Question 8
Examples of Hardware intrupt and Software intrupt
