HEXAGON 680 DSP
The Hexagon 680 DSP comprises three parts for different, specialized tasks – one for processing audio, voice, images and other low-power compute tasks, a 'low-power island' for specially designated sensors, and a third modem DSP that handles global LTE and tasks like carrier aggregation.
This is the first time Qualcomm has implemented a completely separate DSP for sensor processing with the 'low-power island', which can improve the battery life of devices during always-on scenarios, for instance when it is being used as an activity tracker.
In addition, Qualcomm is citing extra horsepower, thanks to something called Hexagon Vector eXtensions (HVX). HVX supports advanced imaging and computer vision when paired with the Spectra ISP. So if you wanted to snap a picture in a poorly-lit room, the SoC would use both ISP and DSP to brighten areas of photos on the fly that would otherwise be too dark.
