How MessageQ to implement interrupts?

Expert 2985 points

Hi TI experts,

***********************************************************************************************

My situation: C6670, CCSv5.2, SYS/BIOSv6.33.6.50, IPCv1.24.3.32, MCSDKv1.1.2.6, XDCv3.23.4.60

***********************************************************************************************

Before I add MessageQ in my current project, I want to make some things clear.

In my project, Core0 has a data in Core0's L2SRAM. Core0 will transfer this data to Core1 and then send a interrupt to Core1 to trigger Core1 to process this data.

As I know, Core0 can use the code below to send a message to Core1(msg contains the data).

status = MessageQ_put(remoteQueueId, msg);

And Core1 can use the code below to get the data in msg.

status = MessageQ_get(messageQ, &msg, MessageQ_FOREVER);

But before Core0 send msg to Core1, Core1 will block at the code above until Core1 gets the msg.

***********************************************************************************************

What I want to do is that Core1 does its normal works and when the Core0 send the msg to Core1, Core1 will go to process the data in msg immediately.

So I want to know if Core0 can trigger Core1 through interrupt after it sends msg to Core1 or not.

***********************************************************************************************

If not, I maybe change my code. Core0 will send IPC notify to Core1 after it put a msg to Core1. And Core1 will get the msg in its IPC Notify callback func and process the data in msg.

status = Notify_sendEvent((DNUM+1)%4, INTERRUPT_LINE, EVENTID, 0, TRUE);

***********************************************************************************************

Are there any other better way?
