Renesas R-Car H1 Automotive SoC

Renesas announced the R-Car H1, their new automotice SoC with 4 Cortex-A9 cores clocked at 1GHz and Imagination Technologies’ SGX-543-MP2 graphics processing unit (GPU) aimed at high-end navigation systems. It also features a Renesas SH-4A high-reliability real-time processing CPU core acting as a multimedia engine (MME) .

The R-Car H1 SoC can also powered with Renesas’ IMP-X3 core (optional), a real-time image processing unit that enables developers to implement augmented reality application such as  360-degree camera views (Thanks to up to four independent input camera channels) and sign recognition.

Here’s an excerpt of the press release:

Renesas Electronics Corporation (TSE: 6723) and its subsidiary, Renesas Mobile Corporation, today announced a new member of the R-Car series of automotive systems-on-chip (SoCs), the R-Car H1, capable of delivering up to 11,650 Dhrystone MIPS (DMIPS), and ideal for the high-end car navigation market. The R-Car H1 SoC offers an innovative architecture where the application domain is powered by an ARM® Cortex™A-9 quad-core configuration running at 1 gigahertz (GHz), while the real-time domain is powered by a dedicated multimedia engine (MME) based on Renesas’ SH4A core. The R-Car’s architecture allows customers 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®.
