NXP: FD-SOI technology to enable lowest power general-purpose processor

NXP Semiconductors markets a new applications processor design that leverages Fully Depleted Silicon On Insulator (FD-SOI) technology to offer the industry’s lowest power consuming general-purpose processor. Coupling FD-SOI with the company’s multiple fully independent domain architecture, NXP’s innovative design delivers a deep sleep suspend power consumption of 15 uW or less, 17 times less in comparison to previous low power i.MX 7 devices, while the dynamic power efficiency is improved by 50 percent on the real time domain. This new design based on FD-SOI’s lower voltage capability enables rich user experience through extremely power-efficient graphics acceleration, a fundamental requirement in many of today’s consumer and industrial battery-operated devices that incorporate robust graphic interfaces. Further enablement includes rich Linux or Android ecosystem with the real-time capability supported by FreeRTOS.

The design’s extreme low leakage and operating voltage (Vdd) scalability is attained through reverse and forward body biasing (RBB/FBB) of the transistors and its smart power system architecture. This high performance, low power solution is optimized for customers developing IoT, home control, wearables and other applications that spend a significant amount of time in standby mode with short bursts of performance-intense activity that require exceptional graphics processing.

NXP’s processor design enables robust low power graphics for the IoT and Wearable markets through two graphic processor units (GPU) from Vivante--the GC7000 NanoUltra 3D GPU with a low power single shader, and the GC320 Composition Processing Core for 2D graphics. The 3D GPU plays a critical role in enabling rich 3D based user interfaces, while the CPC can accelerate both rich 3D and simpler 2D user interfaces. Processors based on the combination of the two GPUs enable efficient display systems which offload and significantly reduce system resources, in turn providing rich user interfaces at low power levels to extend the battery life of devices.
