Multi-Task to Multi-Task event ...

Posted by debugasm on May 1, 2014


I need a little input on how to accomplish this. My project is structured as follows :

Input A - Thread Input A -----+ Input B - Thread Input B -----+ Input C - Thread Input C -----+----- Thread Output A - Output A Input D - Thread Input D -----+----- Thread Output B - Output B Input E - Thread Input E -----+----- Thread Output C - Output C Input F - Thread Input F -----+----- Thread Output D - Output D Input G - Thread Input G -----+ Input H - Thread Input H -----+

Thread Input X running the same code on different input. Thread Output X running the same code on different output.

I have to be able to send from one Thread Input X an event / message or another to all Thread Output X (also not in the same instant).

In my first approach I used a message queue. In Thread Output X I have create 4 message queue on which the Thread Input X write (Thread Output X only read).

On event in Thread Input X I write the same message on all 4 message queue, but it does not seem like the ideal solution.

What technique can I use ? Event Group ?

Thanks for any suggestions.

How detailed is the event? If it can be conveyed as a single bit then an event group would let all the tasks block on the same bits in the same event group with each bit having a different meaning.

Yes, a single bit is sufficient.

Then with an EventGroup of 4-bit size I should be able to simplify things.

I create one EventGroup with 4-bit size, each Thread Input X writes the corresponding bit to wake up Thread Output X. On Thread Output X waiting an EventGroup on single bit.

It should go, I try.

Thanks very much.
