NO RATINGS
So we've been talking about rinky-dinky little processors so far, but I wonder if there is going to be any mention about power-saving techniques with heavy-hitting ARM9/11 processors that can run at 400MHz, 700MHz (Pi), 1GHz (Cubieboard) with an embedded OS such as some Linux distro. I'm currently working on a project where I have to sleep this behemoth and then have it wake up to perform heavy-duty processing when an ext INT/rtcwake is applied. No, it doesn't have a user (interface, push-button finger) and it can't wait the 30 seconds+ while Linux/M$Win/whatever fires up. Any tips to power down all the usual PC-like junk USB/Ethernet/video/SSDs/CPU etc on these boards and have them not consume all the meagre battery capacity when not in use ?
