That may not mean that you have to have an OS tick that small.
If your critical tasks are driven by interrupts, then the
length of the OS tick isn't particulary important -- it's
driven more by the resolution needed on things like the
timeouts you want when waiting for an event that doesn't
happen.

Of course there are.  But you are the only one who knows what
the most important factors are.  If you tell us what those
factors are, perhaps we can tell you how well eCos suits your
application.
