R-Car H2,Overview,the first second-generation R-Car, ~ Technology

Overview

R-Car H2, the first second-generation R-Car, has vastly improved performance

High-end car information systems for 2015 on onwards will demand high-definition displays, instrument cluster, multi-display output to the rear seat monitor, a user experience specialized for automotive, improved responsiveness, and cloud services that use big data. In addition, there will be strong demand for fast startup capability and rendering performance for high-quality design that matches the luxuriousness of the vehicle interior for these embedded devices, as well as field-of-view support for the driver to establish an even higher level of safety, such as a top view monitor that displays not only the back of but all around the vehicle. To respond to these requirements, continuing from the existing R-Car H1 SoC for high-end car information systems Renesas is releasing the first second-generation R-Car, the R-Car H2, which has vastly improved performance.

Features

Achieves the industry's highest performance for an SoC for car information systems of over 25000 DMIPS (double that of the R-Car H1)
The first use of the G6400 high-performance graphics core with the latest PowerVR architecture for automotive
Equipped with the IMP-X4, which has four times the processing performance compared to the R-Car H1, to support OpenCV
More interfaces that are required for next-generation automotive applications (USB 3.0, EthernetAVB, four-channel simultaneous input for high-definition digital camera, three-channel video output, and more)
An ecosystem that includes partner solutions supports the fast development of prototypes and a large reduction in development costs
(Operating systems such as QNX® Neutrino® RTO, Windows® Embedded Automotive, and Linux; board support packages; middleware; and development tools)
