In the comp.arch newsgroup, we've been following a heated discussion about Parallelism. It's focused on the question of designing software to run on multiple cores, either with shared memory or message passing.
We're of the opinion that the compiler can assist the developer in this task. After all, the compiler knows what is (or could be) in memory at any one moment.
printf for embedded
Submitted by Kirk Zurell on Thu, 2009-09-24 20:25. C | debuggingThere's only so much debugging information an LED or LCD display can report. What's worse, embedding debugging code in the executable can provoke misuse, while stripping it out can cause heisenbugs.
Your C compiler can help manage debugging information for you in a way that doesn't interfere with your product. Here's how:

Exceptional Programming
C | interruptsWhat happens to high-level language programming when computer architecture changes? Walter Banks and Kirk Zurell recount the challenges of accommodating novel interrupt architectures in C for embedded systems.
Threads in C
C | threadsOverview
Threads in C require the following:
- A thread declaration, with a dispatch expression.
- A thread function (either a macro, function, or other code).
