Real Time Techniques

There are certain techniques associated with RealTime programming. Often these are described as "Don't do X", where X is some commonly-used non-real-time technique.

• pre-emptive multitasking ("Don't finish one thing before you start another -- don't even wait for a "reasonable stopping point". ")
• keep everything in RAM ("Don't use hard disks")
• make sure everything takes a bounded, predictable amount of time
• don't use mark-and-sweep garbage collection
• Use a RealTime task scheduler, as described in ScheduledTask.

Jean J. Labrosse's book, "MicroC/OS-II: The Real-Time Kernel" (from R&D Books, ISBN 0-87930-543-6 ) is arguably the best book on the topic. Chapter 2, "Real-Time Systems Concepts" is the clearest explanation of RTOS primitives I've ever seen. (I teach embedded and RTOS programming and have programmed embedded and RTOS systems for 30 years.)

someone on the news:comp.realtime 2003-10-10 see also http://ucos-ii.com/

http://www.concentric.net/~Tics/ has several articles on real-time-programming topics.

"Realtime Mantra highlights the key issues in real-time system design. It also cover real-time design patterns and issues in complex software design." http://www.eventhelix.com/RealtimeMantra/

http://surreal-time.com has an online "training course." Kinda fluffy, but useful if you know absolutely nothing.

Is there anything useful at the Embedded Systems Academy http://esacademy.com/ ?

Or http://micro.filetap.com/ ? [BrokenLink as of 27 Nov 10]

Many EmbeddedSystems use RealTimeTechniques.

EditHint: Should I just move all this info to CategoryRealTimePatterns and then delete this page ?

Or at least think about layout ...
