Conclusions

• ARM-based solutions are driving innovation in the fast-evolving wearable and IoT market

• Wearables require lowest power and always-aware functions, along with high-efficiency on-demand performance

• Right CPU configuration and right ‘sized’ implementation are critical for strict low-power budgets for wearable devices – >50% reduction in active power – >90% reduction in idle power

• ARM mbed solution meets the requirement of IoT; lightweight with critical

features including multiple connectivity standards support, end-to-end security, etc.

• ARM provides complete low-power solutions to meet the performance and lowest power goals for all categories of wearable devices – Low power CPU, System IP, GPU and Physical IP for high-end wearable devices
