R-Car-H2

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, Ethernet AVB, four-channel simultaneous input for a 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)
