Automotive infotainment targeted by ARM-based SoC

March 25, 2013 // By Graham Prophet
Renesas Electronics has announced R-Car H2, a complete solution for the high-end multimedia and navigation systems, claiming the highest CPU and graphics performance in this role.

Renesas Electronics and Renesas Mobilehave announced a new member of the R-Car Series of automotive Systems-on-Chip (SoCs). Rated at over more than 25,000 DMIPS, the R-Car H2 provides high performance and state-of-the-art 3D graphics capabilities for high-end multimedia and navigation automotive systems. The R-Car H2 hosts an ARM CortexA-15 quad-core configuration running an additional ARM CortexA-7 quad-core – the industry’s first implementation of a Quad ARM Cortex A15 and the big.LITTLE processing technique in an automotive SoC, Renesas says.

Powerful media hardware accelerators enable features such as four-stream 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. 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), again claimed by Renesas as the first implementation of the GPU into an automotive SoC, for advanced 3D graphics capability. The 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 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 efficient bus architecture of the R-Car H2 includes dedicated CPU and IP caches, enabling Renesas to reduce the DDR3 memory bandwidth consumption. 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. Mobile-product design experience
