Advanced C++ for Embedded Systems

Length: 5 days

view dates and locations

This course is delivered in co-operation with Doulos' training partner Feabhas, who specialise in training courses for real-time embedded developers.

Course Description

Since its standardization in 1998, the support and use of C++ as an embedded programming language has grown significantly. However, until recently most C++ cross compilers were actually “Embedded C++” (EC++) compilers or were typically inefficient in the more advanced areas of the language. To date, a high proportion of programmers using C++ for embedded development have either been unable or have chosen not to use certain features of C++ due to fear of bloated, slow code with poor performance.

This course addresses the “fear, uncertainty and doubt” of using full C++. Specifically the course deals with : performance and memory considerations of polymorphic functions, exceptions and templates. In addition, complete coverage of the Standard Library, including the STL, are covered, again with the specifics of performance and memory models.

Overview

A 5-day course which reviews C++ in the light of real-time systems, addresses the application of C++ in a real-time/embedded environment, and then focuses on the advanced parts of the language. Fifty percent of the course is spent on practical work and the course includes the use of target hardware.

Course Objectives

  • To provide an understanding of the advanced aspects of the C++ programming language
  • To give you practical experience of writing efficient C++ code for real-time & embedded systems
  • To understand the impact different compilers have on performance.

Delegates will learn

  • About memory and performance issues associated with C++
  • How to access hardware, write device drivers, and program interrupt handlers in C++
  • The overheads of exceptions
  • How templates work
  • Different approaches to integrating Real-Time Operating Systems with C++.

Pre-requisites

Some experience of programming with C++.

Who Should Attend?

The course is designed for real-time engineers who either (a) have a working knowledge of C++ but are embarking on a real-time project using C++ for the first time, or (b) have being using EC++ to date and want to extend their knowledge of full C++ for embedded systems programming.

Course Materials

Delegate Handbook.

Course Workshop:

The course makes use of target hardware during the embedded programming practical exercises. The target board is an ARM7-based microcontroller (NXP LPC2129) connected to an application board. Programming the target microcontroller to control the application board gives attendees a real-sense of embedded application development.
