Great course, but quite difficult. I recommend working through all of the problem sets. The video lectures are more important than the textbook readings.

Reviewed on Sep 17, 2017

This is a great course. I learned tremendously.

The only wish is that it is updated with the new materials and the new text book (H&P 6th, planned soon) in the near future.

Frequently asked questions

When will i have access to the lectures and assignments.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:

The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.

The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

Computer system architecture, assignments.

This section contains the problem sets assigned for the course. Each of the problem sets is related to a module. Although problem solutions do not have to be handed in (and consequently, are not graded), it is essential that students become thoroughly familiar with the material and therefore are encouraged to work through all problems.

The self-assessment test was handed out during the first lecture and used to assess each student’s preparation for the course. The test was due one week later in the lecture. The handouts were provided to students to assist them in completing the problem sets. Students were expected to study the handouts before solving the problems. Instructors may request the solutions for these assignments by using the MIT OpenCourseWare feedback form.

Computer Organization and Architecture is used to design computer systems. Computer Architecture is considered to be those attributes of a system that are visible to the user like addressing techniques, instruction sets, and bits used for data, and have a direct impact on the logic execution of a program, It defines the system in an abstract manner, It deals with What does the system do.

Whereas, Computer Organization is the way in which a system has to structure and It is operational units and the interconnections between them that achieve the architectural specifications, It is the realization of the abstract model, and It deals with How to implement the system.

In this Computer Organization and Architecture Tutorial, you’ll learn all the basic to advanced concepts like pipelining, microprogrammed control, computer architecture, instruction design, and format.

Important Notice:No CHANGE in NPTEL Exam Schedule for April 2024

Dear Student,

We wanted to take a moment to address an important matter regarding the upcoming election dates and their potential impact on your exam schedule.

• None of the election dates clash with scheduled exam dates. If we schedule additional dates, we will ensure they again do not clash with elections in your state. 
• Hence this is to confirm that there will be no changes to the exam dates and they are the same as previously scheduled. We may have exams in some cities on April 19 and April 26 depending on seat availability on scheduled dates. But again this will be done ensuring we don't conduct exams on election dates in your state. 
• Your academic progress and success remain our top priority, and we are committed to maintaining the integrity of the examination process.
• We have more than 6 lakh learners registered for April exams and logistics has been a huge challenge. We understand that some of you may need to travel to your native cities to participate in the voting process. Please remember that you selected your exam cities during registration, and it is crucial that you return to these cities to take your exams as scheduled. Since hall ticket and center allocation is under process, exam cities selected by you during exam registration cannot be changed now. 

Hence we kindly request that you make the necessary arrangements to ensure you can both exercise your right to vote and fulfill your academic obligations.

Warm Regards,

NPTEL Team.
