Course ID: IT606
Course: Embedded Systems
Instructor(s): Prof. Kavi Arya, Prof. Krithivasan
Prerequisites: The course assumes that you are already familiar with some microprocessors or micro-controllers and interfacing peripherals. You should have sufficient familiarity with the C programming language.
Scope of the course The "Embedded Systems (Software)" course is targeted at software people who wish to make the transition to working with "embedded systems". We will introduce the various concerns of the embedded system designer and introduce the vocabulary.
The course is mostly software oriented where we presume exposure to microcontrollers and DSPs. For those who have not encountered them a brief exposure will be given in lab-sessions for Microcontrollers and DSPs. Hardware aspects such as board level design, sensors, actuators, drivers, etc. are also out of the scope of this course but are presented as black boxes, where the student is made aware of the issues of interfacing with hardware.
The emphasis is on new paradigms for building embedded systems using technology such as the Esterel language for control-dominated systems and Handel-C for data-dominated applications. We will visit real-time systems and RTOS in detail and go through examples of building embedded applications from scratch. The last month of the course is dominated by project work where the student is given a chance to use their knowledge to build a sizable system in teams.
The course assignments and project are such, that students will pick up a general awareness of the "other side" (ie. their "weaker" side) from the course material, the coursework as well as from their peers by the end of the course.  
Contents:
1. Embedded Systems: Introduction, hardware/software co-design, issues in deciding where to split the problem., examples of embedded systems, sensors and interfacing techniques.

2. Real-time OS and concepts: introducing the problem domain + tools (e.g. RT-Linux), RTOS services/capabilities (in contrast with traditional OS), Resource Management/scheduling paradigms: static priorities, static schedules, dynamic scheduling, best effort, Current best practice in scheduling (eg Rate Monotonic vs. static schedules), Real-world issues: blocking, unpredictability, interrupts, caching, Examples of OSs for embedded systems -- RT Linux, VRT. Case studies, Controlling an Injection moulding process and Flight simulator.

3. Programming Languages for Embedded Systems: - tools for building embedded systems - with case studies. Esterel is good for control applications / Handel-C is good for casting algorithms into re-configurable hardware, Embedded Software Development Methodology.

4. Lab assignments + a project of 1 month duration: a seminar + examples tie the elements of the course together. Students will present seminars on selected embedded system-based applications: smartcards, process-control, robotics, network appliances, etc.
