ERIKA Enterprise Forums

Hi to all,

can someone tell me where can I find informations about Erika\'s aperiodic tasks scheduling? I\'m using EDF in order to schedule periodic tasks in my project, but I don\'t understand how the kernel handle the scheduling of aperiodic ones. Is there a server, like Polling Server, or something else??

Thank you!

When using FP, EDF, or OSEK conformance classes: Aperiodic tasks are handled like any other tasks. You\'ll need to give them a priority or a relative deadline (in EDF). There is not timing protection yet on these conformance classes.

If you need timing protection, you\'ll need to wait for the FRSH conformance class to be available. It will be ready most probably in the final version of EE 1.5.0, as part of the final work of the FRESCOR IST project. FRSH will implement the IRIS scheduling algorithm... but be aware that it will be not as small and fast as the simple FP conformance classes.

Ciao,
