Hi,

Cross Trigger Matrix (CTM) is part of the Cross Trigger Interface (CTI) which are concepts related to multicore debugging (see Cross-trigger network). IPC on the other hand is used to communicate between the cores under normal operations, sending events back and forth. So IPC is what you want in this case. From a firmware perspective, you can start by looking at Inter-core communication.
