Benefits

• Power Savings
• NEMA®|dc has two smart methods to reduce significantly the system power consumption:
• 1)TSCTMFB, Think Silicon Frame-buffer compression: A high quality lossy and 4bpp (bits-per-pixel) fixed rate scheme, which performs in real-time and requires minimal hardware. TSCFB yields into a reduction of frame-buffer size/traffic by 400-800%, depending on the color depth. The reduction of graphics memory size due to TSCTMFB enables systems using only internal on-chip memory by eliminating external DDR memory.
• 2)SSC, Smart Surface Composer: While composing on the-fly surfaces, NEMA®|dc lowers the system bandwidth by eliminating multiple memory read-write cycles and memory volume accesses, compared to a system where the GPU or CPU is entirely in charge of the composition process. SSC yields into a reduction of system bus/memory load by 40-60%, depending on the number and the format of the surfaces.
• TSTMFB and SSC combined are up to twenty (x20) times more power efficient than systems with a conventional display controller.

Deliverables

• Deliverables include: complete set of synthesis, STA (Static Timing Analysis) scripts, OS drivers for Linux, Android, FreeRTOS, portable bare drivers and Android HWC driver.
• Documentation includes: IP manual, integration manual, software-library manual, application notes, demonstration platform, "How To Manual" with bare library application notes including programming descriptions and composition feature enablement.
• A reference design systems and demo-sets are available for platforms: Xilinx Zynq, Altera SoCkit.
• NEMA®|dc documentation includes the IP Manual, Integration Manual, Software Library Manual including example codes, and Application Notes.

Applications

• NEMA®|dc is designed as a flexible back-end of the graphics-video path which works perfect in SoCs with GPU or in tandem with the host CPU in GPU-less systems.
• The possibility to choose from three different versions of NEMA®|dc makes it a perfect candidate to match the budget and suits applications spanning from ultra HD smart TVs (NEMA®|dc-700), to high-mid-range smartphones (NEMA®|dc-400) down to battery-limited embedded systems with simpler graphics requirements (NEMA®|dc-100).
• The Android Hardware Composer (HWC) driver allows NEMA®|dc-700 and NEMA®|dc-400 to act as a surface composer to accelerate graphics requests from the Skia-graphics library, Open Graphics APIs, or any graphics generating application running under the Android system.
