VLSI Signal Processing

Learners enrolled: 3369
Digital signal processing (DSP) has emerged over last two decades as the single most key component in all electronic applications, e.g., multimedia and mobile communications, video compression, digital still and network cameras, mobile phones, radar imaging, acoustic beamformers, GPS, biomedical signal processing etc. Most of these applications impose several challenges in the implementation of DSP systems, like capability to process high throughput data as demanded by the real time application, as well as requiring less power and less chip area.This course aims at providing a comprehensive coverage of some of the important techniques for designing efficient VLSI architectures for DSP. Towards this, architectural optimization at various levels will be considered. The course assumes minimal prerequisites - an undergraduate level knowledge of digital circuit design and elementary DSP operations is sufficient for one to be able to attend the course. Apart from regular students, participants from academia may thus find the course to be useful to develop similar courses at their respective institutions. Alternatively, the course may also be used as a reference by industrial professionals interested in VLSI design of signal processing and communication systems.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
Date and Time of Exams: 24 April 2022 Morning session 9am to 12 noon; Afternoon Session 2pm to 5pm.
Registration url: Announcements will be made when the registration form is open for registrations.
The online registration form has to be filled and the certification exam fee needs to be paid. More details will be made available when the exam registration form is published. If there are any changes, it will be mentioned then.
Please check the form for more details on the cities where the exams will be held, the conditions you agree to when you fill the form etc.


Average assignment score = 25% of average of best 6 assignments out of the total 8 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Certificate will have your name, photograph and the score in the final exam with the breakup.It will have the logos of NPTEL and IIT Kharagpur .It will be e-verifiable at nptel.ac.in/noc.

Only the e-certificate will be made available. Hard copies will not be dispatched.
