Homepod is not the only upcoming Apple product whose software has been detected on Apple's servers. Jonathan Levin discovered BridgeOS a help system that appears to perform a variety of features on Imac Pro.
BridgeOS runs on a 64-bit arm processor that appears to be a modified version of A10 Fusion, the processor running Iphone 7 and Apple TV 4. Steve Troughton-Smith and Guilherme Rambo have also rotated in the code.
Imac Pro seems to use an A10 as a helper processor to handle boot, security and Siri. The last thing is to give your computer support for "Hi Siri", activation with only the voice even if the computer is at rest. Thus, it becomes a way to make Siri more practical and streamlined. The entire Siri can be run on the helper processor.

When you start your computer it looks as if the helper processor is triggered first and passes the boot process to the large Xeon processor. BridgeOS packs up and controls the efi software that controls the hardware of the computer, which in theory can put a stop to various firmware hacks and make Imac Pro more secure.
Troughton-Smith points out that Apple can experiment with this this new, more restrictive architecture without affecting the vast mass of users.
