[FAQ] PROCESSOR-SDK-DRA8X-TDA4X: Targets in OpenVX

Targets in TIOVX are simply tasks or threads running on a given core.  On J7, the default TI SDK supports both Linux and QNX on the A72 and TI-RTOS on the remaining cores. The following section in the TIOVX user guide elaborates on this topic.

In the case that multiple nodes are assigned to the same target, each node assigned to a given target runs to completion, thereby allowing the next node to run that was assigned to that target.

In the case that additional targets are needed beyond the ones provided so that parallel execution on a core can occur, additional targets can be added to the existing list.  The newly created targets can then be assigned to a node via the vxSetNodeTarget API.

For more on the changes needed to add additional targets in TIOVX, please reference the below developer note in our user guide:
