TDA3XEVM: Communication between IPU1_0 and IPU1_1

Kim TaeJung

How can I communicate between IPU1_0 and IPU1_1?

IPU1_1 communicates with a heterogeneous SOC. If a certain condition is met, I want to send data to IPU1_0.

How can I satisfy the above situation?

Which method is better, setting up shared memory or IPC?

What is the data packet size for your IPC communication?

Sorry for the late reply.

The data size is not large.

A simple int type is enough.

You can use the traditional IPC API to send a message.

There is no need to setup a separate Shared Memory given that you are only dealing with a integer payload size.
