Cross-Platform Issues With Floating-Point Arithmetics in C++
Günter Obiltschnig, ACCU Conference 2006  (7 pages, pdf format)
The C++ standard does not specify a binary representation for the floating-point types float, double and long double. Although not required by the standard, the implementation of floating point arithmetic used by most C++ compilers conforms to a standard, IEEE 754-1985, at least for types float and double. The degree to which the various compilers implement all the features of IEEE 754 varies. This creates various pitfalls for anyone writing portable floating-point code in C++. These issues, and ways how to work around them, are the topic of this paper.


Designing and Building Portable Systems in C++
Günter Obiltschnig  (16 pages, pdf format)
C++ covers the whole range from low-level to high-level programming, making it ideally suited for writing portable software. However, code portability is often neglected in embedded systems engineering. With software becoming ever more complex, and hardware becoming ever more interchangeable, this oversight can turn into a problem when software must be ported to a new platform. This paper shows tools and techniques to design and build portable software in C++. It shows how to use C++ features to encapsulate platform-dependent parts (compiler/language differences, operating system interfaces, input/output) of programs, thus ensuring portability of the resulting system.


Using C++ to Create Better Device Software
Günter Obiltschnig  (12 pages, pdf format)
Software for embedded systems is becoming ever more complex. Object-oriented software development is a proven solution for taming software complexity. While, at least to a certain degree, object-oriented principles can also be applied to C programming, a programming language with inherent support for object-oriented programming brings many advantages. But support for object-oriented programming is just one feature of C++. C++ has many features that make writing reliable and robust code easier than in C. This paper introduces two ANSI C++ techniques that can be used to write more reliable and robust code for embedded systems. These are the RAII (Resource Acquisition Is Initialization) idiom for resource management and exceptions for error handling.


C++ for Safety-Critical Systems
Günter Obiltschnig  (5 pages, pdf format)
C++ is now widely used in the development of software for embedded systems, even safety-critical and hard-real-time systems. Even if, due to their design, other programming languages may be better suited for the development of safety-critical systems, there are other relevant factors in favor of C++. Examples are availability of skilled developers and tool support. The public release of the C++ coding standard used in that project (JSF C++), has certainly increased the interest in using C++ for safety-critical systems. In June 2008 the MISRA C++ standard "Guidelines for the use of the C++ language in critical systems" has been released by the Motor Industry Software Reliability Association. Similar to the JSF C++ standard, the MISRA C++ standard defines rules, as well as a "safe" subset of the C++ language for the development of safety-critical systems. This paper gives an overview of both the JSF C++ and MISRA C++ standards and also looks in detail at some of their rules and the rationale behind them. It also shows where both standards differ.


The POCO C++ Libraries for Device Software Development
Version 2.0  (19 pages, pdf format)
This document gives an overview of the Applied Informatics POCO C++ Libraries, a collection of class libraries and frameworks that greatly simplifies the development of network-centric and platform-independent applications in C++. The document is targeted at developers and development/technical managers wanting to get an overview of the functionality and features offered by the Applied Informatics POCO C++ Libraries. Familiarity with the C++ programming language is assumed.


Using Eclipse to Develop for Embedded Linux on a Windows Host
Dr Peter Schojer  (8 pages, pdf format)
Eclipse is an open-source software framework written primarily in Java. While originally only aiding the Java developer, the CDT (C++ Development Tools) add-on provided support for C/C++ projects, syntax highlighting and debugging. CDT relies on a GNU tool chain which must be provided and integrated into Eclipse by the user and on Cygwin as the underlying Unix emulation layer to function properly. This paper will first show how to install all the software required starting with Cygwin. We will then show how to create a cross compiler of your own with Cygwin. The next section covers the installation of Eclipse with additional plugins required for software development. This include subversion access, remote shells and remote debugging. Finally, we will show how one can use Eclipse for remote debugging.


Developing for Embedded Linux on Windows
(33 slides, pdf format)
Overview:
 - Motivation
 - Required Software
 - Creating a Cross Compiler
 - Eclipse
 - Debugging With Eclipse
 - Summary


Automatic Configuration and Service Discovery for Networked Smart Devices
Günter Obiltschnig, Electronica Embedded Conference Munich 2006  (8 pages, pdf format)
This paper discusses the fundamental issues in automatic configuration and service discovery – address assignment, name resolution, service discovery, service description, service invocation and service presentation. Then, four popular technologies that solve some or all of these issues are presented – Zero Configuration Networking, Universal Plug and Play, Jini and JXTA.

Here are several excellent Real-Time Linux Tutorials at isd.mel.nist.gov that introduce and demonstrate a version of the Linux operating system which interacts and communicates with users in real time. These Real-Time Linux Tutorials cover the basics of real time Linux followed by the communication in FIFO (First In First Out) mode. They also explain how tasks are prioritized in a real time operating system; explain the concept of shared communication and semaphores. Examples of real time systems are explained using a servomotor and an LED wand clock.


Real-Time Linux Tutorials:

The Basics
This subdirectory describes about the Linux Task, Kernel Modules and Linux programs. It also tells us that C is the preferred language for Linux programming.

A Single Periodic Task
This example demonstrates a single fixed-period task to read and write I/O address.

Two Periodic Tasks
This example explains about the way two periodic tasks that use shared variables where one task changes the variable and the other one uses this variable.

A Variable-Period Task
This example demonstrates how to set the varying frequency to a single task using timer.

FIFO Communication
FIFO (first-in, first out) is a mechanism of storing data in the using data queue. This example explains how to set up a FIFO data queue to share data between application and tasks.

Interrupt Service Routines
This example shows how to call the functions when an interrupt is triggered from hardware such as timer chips, printers, disk drives, Ethernet controllers, etc.

Shared Memory Communication
Shared Memory is an efficient means of passing data between programs. This example explains how the RT Linux tasks and normal Linux processes pass data using the Shared Memory.

Semaphores
To restrict the simultaneous access to the resources we can use Semaphores. This example explains how to achieve this.

RC Airplane Servomotor Control
This example demonstrates how to control a pair of radio-controlled (RC) airplane servomotors via the parallel port using the GUI.

LED Wand Clock
This Fantazein LED wand clock example demonstrates the implementation of tasking, FIFO and interrupt service routines.

Determining Stack Size
This example demonstrate how to determine the stack size, this helps to allocate the stack size efficiently.

Measuring Timing Jitter
In real time code it is important to quantify timing uncertainty and derive its impact. This example describes that with a pure periodic task, using the Pentium's built-in Time Stamp Counter (TSC).

Floating Point in RT Tasks
This example demonstrates the use of floating-point math in real time tasks.

Data Consistency Techniques
This supplementary material describes various data consistency techniques used to protect the shared data structures. In this supplementary material talks about data consistency techniques such as Dekker's- and Peterson's Algorithms, N-Process Mutual Exclusion using Hardware, N-Reader, 1-Writer Mutual Exclusion using Head/Tail Flags, Semaphores, Mutexes etc.

Here is an SQL Tutorial from Brown University. Learning SQL can be very rewarding and this tutorial covers the SQL (Structure Query Language) syntax and its commands. SQL is used to modify and access data or information from a database, usually a relational database such as Oracle, SQL Server, or MySQL.
