iMac Pro to Feature A10 Fusion Coprocessor for Always-On ‘Hey Siri’ Functionality


Apple’s upcoming iMac Pro will possibly include an A10 Fusion coprocessor for always-on ‘Hey Siri’ functionality. The information has emerged after some digging by developers Johnathan Levin and Steve Troughton-Smith in the BridgeOS 2.0 software from Apple.

Apart from ‘Hey Siri’ functionality, the A10 Fusion coprocessor will also handle macOS boot and security process. This would allow Apple to experiment with tighter security on macOS without frustrating its existing userbase and developers.

Interestingly, as per developer Steve Troughton-Smith, the A10 Fusion chip inside the iMac Pro will presumably even run when the iMac is switched off.

Considering the code has been discovered from Apple’s own software, there is a high probability that the iMac Pro will indeed come with an A10 Fusion coprocessor which will be paired with 512MB of RAM. Apple also uses an arm64 processor called T1 to power the TouchBar on its MacBook Pro lineup. This is also not the first time we are hearing about the possibility of Apple using an ARM processor on its Mac. Beside offering ‘Hey Siri’ functionality and improved security, the ARM co-processor can also be used for the ‘Power Nap’ feature in macOS and other similar features where its higher power efficiency would give it an edge.

Right now, one can only enable Siri’s voice functionality on the MacBook Pro and iMac by pressing the menu button located in the status bar.

Apple had unveiled the iMac Pro at WWDC 2017 this year. The machine is meant for professionals and is scheduled to launch next month. It would feature significantly faster internals than the existing iMac which will include Intel’s Xeon processors, AMD’s Vega GPU, up to 128GB of RAM, and more.
