The answer is... Both! [Embedded Systems Professionals : Greg Havenga]

Tue, 24 Feb 2009 07:59:32 GMT

Microkernels are handy - multithreaded programming is a boon to those who know how to use it,
but it comes with a penalty - the dreaded task switch!

Both the greatest power and any kernel's achilles' heel is task switching. Even in a microkernel,
the amount of time it takes to do a task switch can raise havoc with realtime events such as processing
interrupts, etc., and often demands hardware support (queues on UARTs, etc., ) to deal with the overhead.

Of course, it all depends on your project - I think that if you have the hardware to support it, and your project
is complex enough to require it, the firmware will be cleaner if you you have a microkernel around and can
multitask.

Microkernels rock or suck? [Embedded Systems Professionals : Robert Berger]

Sun, 06 Jul 2008 19:21:42 GMT

If small footprint software loads will become more important, it's time to have a second look at mircokernels.
