If you are not satisfied or couldn’t understood any topic in above videos,you can refer those in below courses.

Some other sources:

course1

course2

course3

course4

Computer Organization by Prof. S. Raman

Answer by bikram sir

Nptel web course

carry and overflow

Assignments:

Do these only after you’re done with previous gate questions.

course1

course2

course3(Highly recommended to solve these assignments)

course4


for some topics like arithmetic you can refer Carl hamacher ,Marris mano.

Note:The above sources are not exhaustive.

I may have missed some topics.But you can cover them through textbooks and while solving questions.

All the videos are taken from this course.Incase i have missed or misplaced any video links,you can refer the nptel course.

Completing Digital logic subject before starting this subject is highly recommended.

I will edit this blog if i find any good sources in future.

Thank you :)

Most people have trouble with Cache Misses. You can go through this:

A CPU uses two levels of caches L1 and L2. It executes two types of
jobs J1 and J2. Their details are as follows:
(A) J1 comes with a probability of 0:3 and requires 2000 memory references,
all for reading. For J1, there are 100 misses in L1 and 60
misses in L2.
(B) J2 comes with a probability of 0:7 and requires 3000 memory references,
all for reading. For J2, there are 50 misses in L1 and 70
misses in L2
The L1 hit time is 2 cycles and the L2 hit time is 10 cycles. The L2 miss
penalty is 200 cycles. What is the average memory access time?

 

Please Sir help me with this .. I am really getting confused about how to approach for this question .
