Overview

The R-Car V3H system-on-chip (SoC) from the Renesas Autonomy™ platform for ADAS and automated driving supports Level 3 and above. It follows the heterogeneous IP concept of the Renesas Autonomy platform™, giving the developer the choice of high performance computer vision at low power consumption, as well as flexibility to implement latest algorithms. (Note 1).

The R-Car V3H SoC is optimized for its application in stereo front cameras and achieves five times higher computer vision performance than its predecessor, the R-Car V3M SoC. The R-Car V3H SoC is focused on architecture optimization for computer vision processing. It enables all relevant ADAS functions from NCAP (e.g. lane keeping, road sign detection and emergency braking) to fully automate driving.

Note 1: NCAP (New Car Assessment Program): A government car safety program tasked with evaluating new automobile designs for performance against various safety threats.

Features
  • 5x higher performance in comparison to the V3M SoC
  • Low power consumption hardware accelerators for key algorithms like dense optical flow, stereo disparity and object classification
  • Dedicated IP for CNN accelerates deep learning
  • Dual image signal processor (ISP) that converts camera sensor signals for image creation and recognition processing
  • Open solution for front camera support by Renesas and its ecosystem of partners
