Hardware, Embedded Systems Having read the feedback resulting from my previous post on interrupts (itself resulting from an earlier OSnews Asks item on the subject), I've had a look at the way interrupts work on PowerPC v2.02, SPARC v9, Alpha and IA-64 (Itanium), and contribute this back to anyone who's interested (or willing to report any blatant flaw found in my posts). I've also tried to rework a bit my interrupt handling model to make it significantly clearer and have it look more like a design doc and less like a code draft.

RE: Locking benchmarks

Member since:

I still argue that a lock free asynchronous model without any threads will easily outperform the "popup thread" model, particularly for simple tasks which consume 1-2K cycles.

This is a very interesting discussion thread, but I'm wondering what kind of model you envision when you talk of a lock-free, asynchronous, thread-less model. Can you point me to a description or more elaborate discussion of such a model?
