NEMA®|pico - the smallest member of the NEMA®|GPU-Series, brings “smartphone-like” 2D/2.5D graphics user- interface experience packed in a very small silicon area for power-budget and cost- sensitive, small display devices with a SoC sporting just a 32Bit MCU. The single-core NEMA®|p GPU is the perfect candidate to support wearable and embedded devices, which don’t need the overhead of a “full” operating system, rather prefer the deterministic approach of a (Free) RTOS and also supports vector graphics where needed. Think Silicon provides to its customers their own proprietary lightweight API, NEMA®|GFX-API and with NEMA®|GUI-Builder a perfect tool to create your own Graphical User Interface (GUI) in a fraction of the time this usually takes.


NEMA®|p has been designed for graphics efficiency in ultra-compact silicon area. Its fixed-point data path and instruction set architecture (ISA) are tailored to GUIs acceleration and small display applications leading to substantial improvements in power consumption and silicon area.

NEMA®|p microarchitecture is based on a lean version of NEMA® ISA and combines hardware-level support for multi-threading, VLIW and low-level vector processing in the most power-efficient way. It features a smart IOMMU for easy integration while eliminating the unnecessary data traffic between host CPU and NEMA®|p.

Software Description

NEMA®|GFX library which is available in pure ANSI C with no dependencies, allows easy portability to systems running RTOS or even to OS-less systems. The software package includes Linux drivers, Software Libraries for 2D Graphics APIs such as DirectFB and comes together with:

  • NEMA®|GUI-Builder, a graphical cross-platform software framework enabling rapid high-end Graphics User Interface (GUI) development on low resource hardware
  • NEMA®|PIX-Presso, a utility software for converting images to/from formats suitable for low power embedded devices
  • DirectFB support makes it an ideal solution for software development with application and Graphic User Interface (GUI) creation frameworks, such as Qt and GTK.

Software Support

  • OS support
    • RTOS (NEMA®|GFX Library in ANSI C)
    • Linux
  • Graphics API support
    • DirectFB
    • Qt
  • Software Emulators and suites
    • NEMA®|PIX-Presso
    • NEMA®|GUI-Builder

Configuration/ Integration/ Verification

NEMA®|p can be customized at design-time choosing from a number of parameters that enable or disable several features of the design. This is done using NEMA®|p GUI Configurator, a Graphical User Interface Configurator Tool.

The NEMA®|p GPU IP Platform is available in Verilog and easy to integrate and verify. NEMA®|p ASIC reference designs have been evaluated in various process technologies.

NEMA®|p is designed with AMBA interfaces. The core has been verified through extensive simulation and rigorous code coverage measurements. It comes together with a complete verification suite that compares reference images with rendered images.
