Overview

NEMA|t is the industry’s smallest Internet-of-Things (IoT) Graphics Processor Unit (GPU) with 3D functionality. The architecture of NEMA|t has been specifically designed from bottom-up for the new generation of superior wearable and IoT display products which require great graphics quality and performance and ultra-low power consumption. The incredibly small silicon footprint of 0.1mm2 (400MHz @ 28nm) has leakage power GPU consumption of just 0.07mW. Implementing Think Silicon’s proprietary compression technologies limits memory power consumption to just 0.03mW (in DDR-less systems). NEMA|t features OpenGL® ES capabilities, implements a fully configurable and programmable 3D graphics rendering engine, accelerates a comprehensive super-set of 2D graphics drawings, and has smart composition functions.

Applications

NEMA|t is, designed to support midrange till higher level quality wearable and IoT devices, such as smart watches, health and fitness applications, smart accessories, alarm systems, home automation, embedded-platforms etc. sporting an SoC with 32-bit MCU or MPU. With NEMA|t, you are be able to create compelling 3D Graphical User Interfaces (GUIs) and software applications with ultra-long battery life or lower power consumption at a significantly lower cost for power-memory-area constrained IoT devices. For example, with core frequencies just as little as 80MHz, NEMA|t delivers a fast and brilliant 3D UI experience in 420x420 resolution, without being limited to these parameters.
