25,000 DMIPS-capable SoC targets the automotive infotainment market

March 25, 2013 // By Julien Happich
Capable of delivering more than 25,000 DMIPS, the R-Car H2 automotive SoC is designed to provide high performance and state-of-the-art 3D graphics capabilities for high-end multimedia and navigation automotive systems.

The R-Car H2 is powered by the ARM CortexA-15 quad-core configuration running an additional ARM CortexA-7 quad-core. Manufacturer Renesas claims this is the industry's first implementation of a Quad ARM Cortex A15 and the big.LITTLE processing technique in an automotive SoC.

Powerful media hardware accelerators enable features like 4 x HD 1080p video en/decoding including Blu-Ray support at 60 frames per second, image/voice recognition and high-resolution 3D graphics with almost no CPU load. These implemented hardware modules also execute the display content improvements needed for human-machine interface (HMI)/navigation data in parallel to Movie/DVD handling.

The R-Car H2 also features the Imagination Technologies PowerVR Series6 G6400 Graphics Processing Unit (GPU). This GPU is ready to not only support open technologies like OpenGL ES 2.0, but also the OpenGL ES 3.0 and OpenCL standards.

Renesas’ IMP-X4 core, implemented in R-Car H2 as an optional feature, provides real-time image processing that enables developers to support the emerging trend of augmented reality. In order to fully benefit from the IMP-X4 core, the R-Car H2 also supports up to four independent input camera channels, allowing easy implementations of 360º camera views and image recognition, just an example of the possible driver assistance functions. OpenCV support for IMP-X4 will also be offered. The R-Car H2 offers the highest level of integration of advanced safety concepts and infotainment features in the automotive market today. In order to ensure adequate memory bandwidth, the R-Car H2 is equipped with two independent DDR3-1600 32-bit interfaces. This allows for much more efficient access to different content simultaneously, compared to a single 64-bit DDR interface.

The R-Car H2 integrates advanced automotive interfaces like Ethernet AVB, MOST-150 and CAN and mass storage interfaces like SATA, USB3.0/2.0, SDcard and PCI Express for system expansion. As a device option, the GPS baseband engine handles all modern navigation standards. A 24-bit DSP for codec, high-quality audio processing with hardware sample rate converters and audio mixing is
