What are the methods of multi-core communication in MPC5748G?

Dear Community,

Is there a way to communicate between multiple cores on MPC5748G besides writing memory? Is there a way for one core to produce an interrupt in another core?

Ok, thank you very much, I will check this topic.

Hello,

Yes, core can produce interrupts. The INTC on this chip supports 3 cores (0, 1 and 2) and 16 level priorities of each
interrupt.

For handling multicore application best is to use SEMA4 units. Here is the example, principle is the same.

Please refer to the reference manual for more details. SEMA4 and INTC chapter.
