The device takes advantage of the system trace infrastructure to provide visibility to the user regarding IVA microtask sequencing. This is supported through a SMSET module instantiated in the IVA subsystem. The microtask boundaries are handled as generic events and encapsulated in STP messages with an event-ID and local timestamp and exported through the CT_STM module.
The IVA instrumentation scheme allows the user to understand microtask dependencies, hardware accelerators load balancing, and potential bottlenecks. DMA transfer boundaries are reported as IVA events. Software messages from Arm968 execution can be interleaved with IVA events.
