Renesas Electronics Corp. and Renesas Mobile Corp. have expanded their R-Car Series of automotive SoCs. According to them, the R-Car H2 can deliver more than 25,000 DMIPS and can provide high performance and modern 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 companies added.

Renesas said powerful media hardware accelerators enable features that include 4 x HD 1080p video en/decoding including Blu-Ray support at 60fps, 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 GPU. The R-Car H2 also offers one of the best graphic performance solutions in the automotive embedded market, Renesas claimed. This GPU is ready to not only support open technologies such as 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 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 32bit interfaces. This allows for much more efficient access to different content simultaneously, compared to a single 64bit DDR interface, the company indicated.

The R-Car H2 integrates advanced automotive interfaces such as Ethernet AVB, MOST-150 and CAN and mass storage interfaces that include SATA, USB3.0/2.0, SDcard and PCI Express for system expansion, said Renesas. As a device option, the GPS base band engine handles all modern navigation standards. Even here, the integration level of R-Car H2 doesn't stop. A 24bit DSP for codec, high-quality audio processing with hardware sample rate converters and audio mixing is part of the enormous function coverage. The Renesas R-Car family provides the highest level of advanced automotive peripherals in the market today. The Renesas Ethernet AVB solution achieves the fullest implementation of Ethernet AVB on the market, offering the Full Ethernet AVB specification and meeting the specification requirement demands of the automotive market.

The R-Car H2's multi-core architecture allows customers to implement real-time features, such as quick-boot, backup camera support and media processing, parallel to the execution of advanced operating systems such as QNX Neutrino RTOS, Windows Embedded Automotive or Linux. Samples of the Renesas R-Car H2 SoC are available, equipped in an 831-pin FCBGA (flip chip ball grid array) package. Mass production is scheduled for mid-2014.
