Renesas has selected Arteris’ FlexNoC network-on-chip (NoC) interconnect IP for its latest R-Car Gen 5 SoC family, designed for advanced driver-assistance systems (ADAS) and automated driving (AD) applications. The Arteris NoC technology forms the data backbone of these high-performance, energy-efficient, AI-enabled SoCs that will power the next generation of autonomous vehicles.
The flagship R-Car X5H SoC, now sampling, delivers exceptional image recognition performance and object processing using inputs from automotive cameras, radar, and lidar. With AI acceleration capabilities of up to 400 TOPS, the X5H offers remarkable compute throughput.
It also supports UCIe protocol-based chiplet extensions, enabling up to a 4× increase in AI performance. Within the SoC, the native NPU and GPU engines, as well as Arm CPU clusters, are interconnected through Arteris’ FlexNoC IP to ensure fast, efficient data movement across the system.
Built using TSMC’s 3 nm automotive process, the X5H achieves a 30–35% reduction in power consumption compared to previous process generations.
This improvement helps lower system costs by reducing thermal management requirements and extends vehicle driving range all while maintaining compliance with ISO 26262 ASIL D functional safety standards.
Arteris’ FlexNoC interconnect IP plays a key role in enabling these gains. Its advanced physical awareness and design optimization features shorten development cycles, enhance performance, and improve energy efficiency critical for mission-critical use cases like autonomous driving.
