Configuring Changeable Embedded
Systems
By Eric McRae
Here are some guidelines for designing and implementing software to handle
configuration in changeable systems. The example is the energy control
system for Tera Computer Company’s new supercomputer.
Solving the Software Safety Paradox
By Doug Brown
Embedded systems running safety-critical applications have a quandary. How can the software know that it’s operating correctly? Can a
malfunctioning system diagnose itself and either correct the problem or
halt itself? This article examines some techniques that allow the software
to monitor itself, with a bias toward those techniques that can easily be
implemented in almost any embedded system.
Requirements Management Using Tables
By Bob Petty
Requirements efforts for embedded software projects are conducted with a
wide range of formality. This article describes how to maintain
requirements in a simple tabular form that can be adapted to all types of
projects.

Static vs. Dynamic Initialization
If you read the C++ standard carefully, you can reasonably deduce that C++
compilers have about as much latitude to place objects into ROM as C
compilers do. But you have to read very carefully.
