I am somewhat confused over the CPU design. Does anyone know what the reason or advantage is for having 2 different architecture processors running at different clock speeds in the same SOC sharing the same ram?
Was this an accident or did it serve a specific purpose?
- alexisread 4y agoI think it's for hi/low power switching- radio stacks and ML models can be shared, so you don't need to reinitialise them, and you can activate only the high power cpu when required. Farmbots and wearables are a couple of applications that would match this pattern. Camera AI and radio but running on battery.
- BizarroLand 4y agoInteresting! I didn't consider power draw at all. That is kind of weird as the whole system only draws (5v/0.5a = 2.5w) and I can't find anything that states that the power draw would radically alter for utilizing only 1 core. At 2.5w a 10,000wh battery would run this non-stop for weeks.
