Renesas Electronics and Renesas Mobile Corporation have unveiled a new member of the R-Car Series of automotive Systems-on-Chip (SoCs). Capable of delivering more than 25,000 DMIPS, the R-Car H2 is able to provide high performance 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 – 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 are able to support 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 features the Imagination Technologies PowerVR Series6 G6400 Graphics Processing Unit (GPU), which is the first implementation of the GPU into an automotive SoC. 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 making it a suitable platform to develop next-generation infotainment systems
Renesas’ IMP-X4 core, implemented in the R-Car H2 as an optional feature, provides real-time image processing that will enable 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. OpenCV support for IMP-X4 will also be offered.
The bus architecture of the R-Car H2 includes dedicated CPU and IP caches, enabling a reduction in 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.
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.
Renesas is also offering a robust ecosystem, including board support packages (BSPs), middleware, development environment and partner solutions, which enables quick prototyping and drastic reduction of high-end product development costs.
