Renesas introduces 2nd-gen R-Car H2 CPU for coming high-end multimedia and navigation systems

Renesas Electronics Corporation (semiconductor solutions), and Renesas Mobile Corporation (advanced cellular semiconductor solutions and platforms), announced the availability the first second-generation R-Car automotive Systems-on-Chip (SoC), the R-Car H2, which offers significantly improved performance over the current R-Car H1 SoC. Capable of delivering more than 25,000 DMIPS (Dhrystone MIPS), the R-Car H2 provides high performance and state-of-the-art 3D graphics capabilities for the high-end multimedia and navigation automotive systems anticipated in 2015.

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

Media hardware accelerators enable features such as 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 is the first worldwide implementation of the GPU into an automotive SoC, which demonstrates the advanced 3D graphics capability of the R-Car series. The 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. Support of the Open graphics standards combined with the R-Car H2’s cutting-edge IP and other features makes it a suitable platform for next-generation infotainment systems, according to the company.

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 implementations of 360° 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 32-bit interfaces. This allows for 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, SD card and PCI Express for system expansion. As a device option, the GPS baseband engine handles all modern navigation standards.

With the R-Car H2, Renesas also provides 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.

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 from today, equipped in a 831-pin FCBGA (flip chip ball grid array) package. Mass production is scheduled for mid-2014. (Availability is subject to change without notice.)
