Dusseldorf, Germany: The R-Car H1 automotive system-on-a-chip (SoC) from Renesas Electronics delivers up to 11,650 Dhrystone MIPS for the high-end car navigation market. Its architecture offers an application domain powered by an ARM Cortex A-9 quad-core configuration running at 1 GHz (see the figure). A dedicated multimedia engine (MME) based on the Renesas SH4A core powers the real-time domain.
The architecture enables designers to implement features such as quick-boot, backup camera support, and media processing using the MME, while the application domain cores can be allocated to run advanced operating systems such as Linux, Windows Automotive Embedded, or QNX.
The Renesas IMP-X3 core, a real-time image processing unit that enables developers to respond to the emerging trend of augmented reality, also can power the R-Car H1 SoC. To fully benefit from the IMP-X3 core, the R-Car H1 SoC supports up to four independent input camera channels, allowing implementation of 360° camera views and sign recognition as well as other applications.
Integrated peripherals include Ethernet, MOST-150, PATA and SATA interfaces, and PCI Express for system expansion. The R-Car H1 SoC also offers a version with a GPS baseband engine, enabling further system integration. The R-Car series offers multiple CAN channels, two independent display controllers, and three USB 2.0 ports with physical layer (PHY).
