A Norwegian startup is pushing the limits of low power in microcontrollers, cutting power by a factor of four over even 8bit devices. Energy Micro has developed the EFM32 low power 32bit microcontroller based on the ARM Cortex-M3 architecture with low power clocks and peripherals that consumes less than 180µA per MHz while executing real life code from Flash memory and the lowest active mode

True wireless speakers emerge with Audium
Posted on 02:53 by Unknown
The main problem with "wireless" speakers is that they aren't - you end up replacing the speaker cable with a power cable, which can give you some advantages but really isn't the point.Now, a Bristol startup aims to provide true wireless speakers with an audio amplifier that uses just 5% of the power of traditional amplifiers.Audium Semiconductor has developed an amplifier architecture that can
