Renesas Electronics Corp. and Renesas Mobile Corp. have expanded the R-Car series of automotive SoCs with the release of the R-Car H1. The device enables features such as quick-boot, backup camera support and media processing using a dedicated multimedia engine (MME) based on Renesas' SH4A core.

The SoC can deliver up to 11,650 Dhrystone MIPS (DMIPS) and is designed for high-end car navigation systems. The R-Car H1 offers an innovative architecture where the application domain is powered by an ARM CortexA-9 quad-core configuration running at 1GHz, while the real-time domain is powered by an MME, said the company. The application domain cores can be allocated to run advanced OS such as Linux, Windows Automotive Embedded or QNX.

R-Car H1 features quick-boot, backup camera support and media processing.

Renesas' R-Car H1 SoC is powered with Imagination Technologies' SGX-543-MP2 GPU, and delivers up to 40 gigaflops per second (Gflops/s, effective). The GPU is ready to support open technologies OpenGL ES 2.0 and OpenVG 1.1, making it a perfect platform to develop next-generation car infotainment systems, added Renesas.

As an optional feature, the device is also powered with Renesas' IMP-X3 core, a real-time image processing unit that enables developers to address the emerging trend of augmented reality. To fully benefit from the IMP-X3 core, the R-Car H1 SoC also supports up to four independent input camera channels allowing easy implementation of 360-degree camera views and sign recognition.

Video and audio processing is supported by hardware accelerators supporting up to HD 1080p@60fps on advanced infotainment systems. To ensure adequate memory bandwidth, the R-Car H1 SoC is equipped with two independent DDR3 32bit interfaces that allow access to different content simultaneously, providing higher performance when compared to solutions that offer a single 64bit DDR interface, the company claimed.

For system expansion, the R-Car H1 integrated peripherals include Ethernet, MOST-150, PATA and SATA interfaces, and PCIe. To enable further system integration, the SoC offers a version with a GPS baseband engine. It provides multiple CAN channels and two independent display controllers as well as three USB 2.0 ports with PHY.

Samples of Renesas' R-Car H1 SoC will be available November this year, in 832-pin flip-chip ball-grid array (FCBGA) package. Mass production is scheduled to begin in December 2012 and is expected to reach a cumulative 100,000 units per month in December 2013.
