Renesas R-Car H2 is an Octo Core big.LITTLE Processor for Your Car

Renesas announced a new automotive SoC called the R-Car H2 that features 4 Cortex-A15 cores together with 4 Cortex A7 cores (optional) in big.LITTLE configuration, as well as an Imagination PowerVR Series6 G6400 GPU. This SoC can optionally come with Renesas SH-4A, a real-time processing CPU core acting as a multimedia engine (MME) , and Renesas’ IMP-X4 core, a real-time image processing unit that enables developers to implement augmented reality application such as 360-degree camera views and image recognition.

This Renesas processor is a multimedia power house, as it can handle 4x 1080p video en/decoding, including Blu-Ray support at 60 frames per second, as well as image/voice recognition and high-resolution 3D graphics with virtually no CPU usage.
