Acerca de este Curso

This course can also be taken for academic credit as ECEA 5315, part of CU Boulder’s Master of Science in Electrical Engineering degree.
Course Description: In this course, students will design and build a microprocessor-based embedded system application using a real-time operating system or RT POSIX extensions with Embedded Linux. The course focus is on the process as well as fundamentals of integrating microprocessor-based embedded system elements for digital command and control of typical embedded hardware systems.

Lab Description: The course requires the student to install embedded Linux on the Raspberry Pi ARM A-Series System-on-Chip processor.  This course must be completed using a Raspberry Pi as an embedded system (headless) not a PC running Linux. You will however find Linux as a useful host development system or Windows with an SSH terminal access tool such as Putty, MobaXterm, or equivalent.

Acerca de Programa especializado: Real-Time Embedded Systems

The Real-Time Embedded Systems specialization is a series of four course taking you from a beginning practitioner, to a more advanced real-time system analyst and designer. Knowledge and experience gained on hard to master topics such as predictable response services, when to allocate requirements to hardware or software, as well as mission critical design will enhance your engineering talent. You will gain experience building a simple, but real, system project with real-time challenges, that will boost your confidence.

The hands-on, at home, project hardware is affordable, widely available, and quick-time-to market methods leverage Linux real-time extensions, open source RTOS (Real-Time Operating System), as well as tried and true cyclic executives. After you complete all four courses in the series, you can consider yourself an intermediate to more advanced real-time system practitioner. This knowledge is invaluable for medical, aerospace, transportation, energy, digital entertainment, telecommunications, and other exciting embedded career options. The series stresses hands-on practice and assessment of your learning progress, not only based on knowledge acquisition, but by teaching you to put theory into practice and how to evaluate design options and make optimal choices. The unique final project allows you to see real-time challenges with your eyes, to debug interactively, and build a simple at-home detection, tracking and synchronization system.
