General Purpose Queue Interrupt?

Alberto Chessa

Hi,

Just to be sure if I have correctly understood the documentation, there are no way to have an interrupt (event) on an Rx general purpose queue? I have always to use an accumulator queue?

Alberto,

I'm not sure what thread this is associated with, but you'll need to go back to the thread and reply to that thread instead of posting a new thread. There's a box in red labeled 'Reply' that you can hit to reply to the thread.

Best Regards,

Chad

This is a new thread. Just a question about my understanding of the QM of C6678.

Best regards

Sorry for the misunderstanding, can you reference what documentation you're speaking of?

Best Regards,

The event and interrupt mapping section speek only about the interrupts/events generated by queue 0..669 and say nothing about the other general purpose queue. This should means that the GP queue cannot directly generate interrupts to the DSP. It is reasonble since they are about 8000 and it is not possible to have a different event for every queue. Anyway, I wonder if there is a way to get an event from the GP queue without using an accumulator.

Hi,

this message is just to close the thread: I read agin the documentation. GP queue cannot generate interrupt but there are queues from 652 to 671 that can do it. I supposed I cannot use that since the interrupt names (qm_int_pass_txq_pend_12...) make me think they are reserved some PASS transmit business. I have tried to use one and it works.
