Concurrent interfaces

Hi,

Can two sporadic PIs in the same TASTE function execute concurrently, or is this prevented by TASTE? Same question for one Cyclic PI and one sporadic PI. The scenario is accessing shared data: the cyclic calls a RI to send this data and the sporadic(s) update this data when called.

If the mutex is not enforced by TASTE, I suppose one can use OS mutex primitives in the user code instead, right?

(this question came up when reading slide 17 of Taste_training.pdf)

Thanks!
