Fujitsu Semiconductor America today (21 October) introduced the Fujitsu MB86R11 2D/3D Graphics System-on-a-Chip (SoC) with an integrated GDC and GPU.
The SoC provides sophisticated graphics and effects for instrument cluster and Advanced Driver Assistance Systems (ADAS). The design of the MB86R11 makes it suitable for deployment with the newly announced Fujitsu 360-Degree Wrap-Around Video Imaging Technology

The Fujitsu MB86R11 ‘Emerald-L’ packs considerable graphical processing power into a compact 544-ball PBGA package. Based on the 400MHz ARM Cortex™ A9 processor and custom graphics core, the SoC delivers two- and three-dimensional graphics.
The graphics core, which is OpenGL 2.0-compliant, features a unified shader array and 16 parallel floating point units. Three independent display controller units (DCUs) built into the graphics core support up to five displays total and four independent video-capture inputs.
The MB86R11 ‘Emerald-L’ graphics SoC also incorporates a memory controller, power management unit, and a range of peripheral and high-speed interfaces.
“The MB86R11 ‘Emerald-L’ represents highly innovative, efficient and integrated graphics system-on-a-chip technology for advanced automotive applications,” said Dan Landeck, senior manager for marketing at Fujitsu Semiconductor America.
“It builds on the successful Fujitsu MB86298 ‘Ruby’ graphics processor, which was the first to provide four displays and four video inputs on a single IC. The combination of an OpenGL ES 2.0 GPU and Fujitsu’s display controller technology enables the MB86R11 ‘Emerald-L’ to deliver 2D/3D graphics performance.”
Since 2D technology efficiently produces many common graphical effects, a proprietary 2D core complements the shader architecture. This 2D engine, which includes Fujitsu’s new PixBlt unit, can process selected graphics without using the GPU.
The PixBlt unit offers a variety of functions related to blending, anti-aliasing, and many levels of filtering. By offloading less complex graphics tasks from the GPU to the 2D engine, the MB86R11 design enables graphics quality while minimising processing overhead and memory access.
This reduces power consumption and allows the chip to run without the need for active or passive cooling.
The unified shader array of the MB86R11 supports vertex and fragment shaders. The pipeline allows for OpenGL ES 2.0-compliant graphics and drawing features such as anti-aliased graphical object drawing. The array incorporates 16- and 32-bit pixel color formats, a 32-bit pixel format frame buffer, and textures for RGBA, ARGB, and ABGR colour ordering.
A ‘visibility enhancement’ feature performs adjacent pixel comparison to reproduce images with natural colours. A flexible graphics ‘signature’ unit offers automotive system developers an efficient method for verifying data integrity.
The MB86R11 supports up to 1GB of 32-bit DDR3-800 or DDR2-800 memory and uses a unified memory architecture that allows access to the memory by the processor core and graphics engine.
This enables the MB86R11 to provide a maximum memory performance of 3.2GB/second. The SoC’s power management unit allows the selective disabling and enabling of its core to control its power consumption at specific times. The device also features several low-power standby modes and external memory auto refresh.
