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.

The LG G5 is just one of the lat­est flag­ships to fea­ture the Snap­dragon 820.
