New technology...31pc reduction in power consumption

Toshiba develops low power control technology

TOKYO, April 16, 2015

Toshiba Corporation has developed an innovative low power control technology for micro controllers supporting multi-sensor wearable devices.

Applied to an activity monitoring application using the company’s TZ1001MBG microcontroller (MCU), the new control technology achieved a 31 per cent reduction in power consumption, said a statement.

The goal for battery-operated wearable devices is a long run time without charging, with a physically small battery and requires power-saving technologies.

MCU embedded in wearable devices typically support several low power modes that is the devises is idle automatically. But the transition from low power mode to active mode requires some power consumption. This requires wearable devices to reduce the frequency of mode transition.

However, the number of sensors embedded in wearable devices is increasing, requiring the microcontroller to respond to sensors more frequently, with a mode transition every time it does.

Toshiba’s technology reduces the frequency of the mode transition by gathering the separate data acquisitions from multiple sensors which get data at their own regular intervals. In this way, the number of mode transitions can be decreased, hence the reduction of power consumption from mode transitions is achieved.

On the other hand, if aggregating leads to significant failures in data acquisitions, it will have a considerably negative impact of the functions of the application, such as step measurement or behaviour analysis in activity monitors. Toshiba has developed an aggregating method that optimising timing of data acquisition to suppress failures. - TradeArabia News Service
