Renesas has released its fifth generation of R-Car SoCs for automotive applications. All About Circuits attended Renesas' press conference at Electronica presented by Vivek Bhan, senior vice president and general manager of high-performance computing.
There, we learned details of how the new R-Car SoCs may meet the evolving demands of centralized compute architectures and software-defined vehicles (SDVs).
New R-Car SoCs for Automotive Centralized Compute
The new lineup, led by the R-Car X5H, is built around 32 Arm Cortex-A720AE cores, collectively delivering performance up to 1000k DMIPS for high-level ADAS and autonomous driving features. To address real-time processing requirements, the R-Car X5H also includes six Arm Cortex-R52 cores operating in dual-lockstep, delivering over 60k DMIPS and supporting Automotive Safety Integrity Level D (ASIL D).
Altogether, the SoC achieves up to 400 TOPS of AI processing, facilitated by an optimized neural processing unit (NPU) and digital signal processor (DSP).
The R-Car Gen 5 SoCs offer high-end graphics processing via a high-performance GPU. With up to 4 TFLOP graphics processing, the graphics subsystem supports multi-4k media processing, multi-megapixel camera inputs, and multi-display outputs.
From an efficiency standpoint, the fifth-generation solution leverages a 3-nm process technology to achieve a 30–35% power improvement over its 5-nm predecessors. Energy efficiency is further enhanced through an integrated system control processor (SCP), which manages various low-power modes for specific applications like parking or sentry mode.
