CSCI1600: Embedded and Real Time Software Lecture 1: Course Introduction Steven Reiss, Fall 2017 Lecture 1: Course introduction 12/1/2018

What is CSCI1600 Purpose: Teach how to build and program embedded and real time systems. What is an embedded system What is a real time system Lecture 1: Course introduction 12/1/2018

Why are these important Everything today has embedded processors How many CPUs are in a modern car? Other examples Lecture 1: Course introduction 12/1/2018

What are the differences Traditional User interfaces & usability Flexibility Performance Maintainability Expected time Data oriented Timing unimportant Amortized cost Software Design RT/Embedded Emphasis on I/O Predictability Reliability Fault tolerance Worst case time Control-oriented Timing essential Minimize cost Hardware-Software co-design Don’t get into details of RT/E systems. Save that for next time. Lecture 1: Course introduction 12/1/2018

The Course Learn the underlying concepts Learn the underlying theory Writing embedded and real time code Experimenting with real hardware An interesting project of your choice Lecture 1: Course introduction 12/1/2018

Practical Underpinnings Micro-processor architectures Low-level input/output Real-time data and control structures Real-time operating systems Interprocess communication Security Lecture 1: Course introduction 12/1/2018

Theoretical Underpinnings Automata-based modeling Continuous, real-time Discrete, hierarchical, concurrent Real-time scheduling Verification Worst-case execution time Lecture 1: Course introduction 12/1/2018

Project Ideas THEME: Smart-Home (Office, Building, …) You are more creative than I am Pinball Smart clothing Robotics Research Project Something you always needed Lecture 1: Course introduction 12/1/2018

Hardware We are using Arduino Unos for homeworks For final projects Purchase your own (we have some to lend) We will get a shopping list of parts needed We will supply incidentals For final projects Buy yourself and keep Brown buys and you return We will supply incidentals if we have them Lecture 1: Course introduction 12/1/2018

Questions Lecture 1: Course introduction 12/1/2018

Assignment Read chapter 1 Take a common device in your life Describe what the embedded software does and how it might work You don’t have to be accurate – I’d rather you think about how you might accomplish what it does rather than looking up what it really does How does a toaster work? Be prepared to discuss Lecture 1: Course introduction 12/1/2018
