Renesas drives eight-core ‘big-little’ into automotive

Renesas has introduced the R-Car H2, an SoC with a 4.4 big-little processor configuration and 3-D graphics capabilities for high-end car infotainment systems.

PARIS – Renesas Electronics and its subsidiary Renesas Mobile Corp. have announced the addition of the R-Car H2 system-chip to the R-Car Series of automotive SoCs.

With four Cortex-A15 and four Cortex-A7 processor cores it is intended to provide higher CPU performance for the automotive infotainment market.

The processor cores are licensed from ARM Holdings plc (Cambridge, England) while Renesas has selected the ‘Rogue’ PowerVR G6400 GPU from Imagination Technologies Group plc (Kings Langley, England) for the 3-D graphics rendering.

The complex chip includes media hardware accelerators to execute the display content improvements necessary for human-machine interface, navigation data and Movie/DVD handling.

The R-Car H2 includes PowerVR Series6 G6400 GPU to support open technologies like OpenGL ES 2.0, but also the OpenGL ES 3.0 and OpenCL standards.

Renesas noted that the bus architecture has dedicated CPU and IP caches 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.
Renesas said the R-Car H2 chip is available now.
