The RH850/U2B next-generation 28nm cross-domain automotive control microcontroller series realizes up to 8 cores x 400MHz incl. Virtualization Support and Quality-of-Service (QoS). The RH850/U2B is equipped with the latest HW-support technologies to realize the integration of multiple ASIL-D SW-partitions into one ECU while ensuring Freedom-From-Interference between the concurrently running applications to meet the ISO26262 ASIL-D standard.
To enhance the performance level for real-time control the RH850/U2B will be partly equipped with the ASIL-D capable DR1000C, a RISC-V based parallel coprocessor IP with vector extension. The DR1000C is ideal for offloading heavy-load arithmetic processing e.g. to cover upcoming requirements, like EU7 exhaust emission legislation in Europe.
Motor/generator-control is the key technology for the electrification trend of all vehicle types. The integrated and comprehensive Renesas solution for traction inverter control incorporates a stand-alone high-performance motor-control accelerator IP (EMU3S) that works in flexible conjunction with multiple dedicated motor-control timer structures like GTM v4.1 and TSG3. As a unique feature, the embedded motor position sensor interface RDC3X (covering resolvers as well as inductive position sensors) provides the option to achieve significant BOM-cost reduction because the usually required external RDC chipset may be omitted.

To practically reduce the overall number of ECUs in a car, their functions must become integrated as multiple virtual ECUs on a shared physical ECU. A solution to this challenge is the introduction of a hypervisor-related SW system – developed in cooperation between ETAS and Renesas.
To achieve freedom from interference between integrated applications of a zone control ECU, several HW measures are implemented:
Parallel co-processor DR1000C (data flow processor):
The DR1000C is licensed from NSITEXE, Inc. of Japan. NSITEXE is an IP vendor, established in 2017 as a spin-off from DENSO Corp., specializing in the development of advanced processors.
The DR1000C is required by automotive microcontrollers which are targeted for safety critical systems. Up to 16 hardware threads can efficiently utilize the vector processor, thereby achieving extremely high-power performance.
