Ground Rules

Online discussions

We will use Piazza as the primary mode of online discussion for this course. Please visit the course page and sign up as a student using the access code announced in class. Rather than emailing questions to the teaching staff, I encourage you to post your questions on Piazza.

Reading Material


Software needed for lab work

You will need to download and install the following software on your laptops for the lab assignments and for your final project.

Practice Questions and Exams

Please see last two years' (2016, 2017) course pages for old problem sets (practice and exam).

Lecture Schedule

DateTopics
Jan 5 Introduction, course logistics, motivation for turning algorithms to circuits, basic logic gates, truth-tables and designing circuits from them, introduction to Karnaugh maps (K-maps)
Jan 11 More on K-maps and optimizing inputs of AND/OR gates in two-level AND-OR circuits, design of some basic building blocks: half-adder, full-adder, n-bit ripple-carry adder, Discussion of nominal delays through ripple carry adder.
Jan 12 More on adders, design of n-bit carry lookahead adders and nominal delay analysis, design of n-bit comparators and multiplexors. Converting simple programs to circuits using the datapath blocks (adders, comparators, multiplexors) learnt so far.
