Renesas Electronics RH850/U2B is an automotive SoC designed for electronic control unit (ECU) with used for hybrid ICE and xEV traction inverter, high-end zone control, connected gateways, and vehicle motion applications.

The processor includes up to eight 400MHz RH850 32-bit RISC performance cores with four of them in lockstep architecture for ASIL-D and ASIL-B compliance, as well as DR1000C RISC-V-based parallel co-processor (data flow processor) with vector extension (DFP) from NSITEXE designed to support “the fast execution of complex mathematical algorithms”.
