Andes Technology is working with Green Hills Software (GHS) on an integrated RISC-V automotive safety platform with hardware and software.

This will use the AndesCore 25-Series family of RISC-V cores running the safety-certified µ-velOSity real-time operating system (RTOS), the ASIL-certified MULTI development environment with advanced system-level debugging and analysis tools and C/C++ optimizing compilers, along with the Green Hills Probe for JTAG and trace target connections.

The combined hardware and software is designed for system on chip (SoC) companies and end-customers to create 32bit and 64bit RISC-V-based chips targeting critical functions requiring ISO 26262 ASIL B to ASIL D safety requirements. THi s is expected to be available for general licensing by the end of 2022.

The processor is based on AndesStar V5 architecture incorporating RISC-V technology with a 5-stage pipeline is optimized for high operating frequency and high performance. The 25-Series supports optional single- and double-precision floating point instructions along with branch prediction for efficient branch execution, instruction and data caches, local memories for low-latency accesses, and ECC for L1 memory soft error protection. Multiple power management settings enable efficient energy consumption.

The N25F-SE, a member of the 25-Series family, is currently at the final stage of being certified at ASIL-B.

“AndesCore RISC-V processor IP with safety enhancement has already been adopted by several early customers due to its unique and competitive value,” said Dr. Charlie Su, President and CTO of Andes Technology, which was the first RISC-V processor IP vendor to receive ASIL D process certification for both hardware (ISO 26262-5) and software (ISO 26262-6).

“The exciting partnership with Green Hills Software enables us to further offer comprehensive and robust development support for our customers. We welcome the benefits that Green Hills Software’s mature functional safety solutions bring to the RISC-V community to speed up the adoption of RISC-V safety-related applications,” he said.

“We are pleased to expand our production-ready safety solutions support to include the latest advanced safety-certified RISC-V AndesCore IP from technology leader, Andes Technology,” said Dan Mender, Vice President, Business Development, Green Hills Software. “And with this combined hardware-software solution, SoC providers utilizing the AndesCore 25-Series family can immediately start developing their next generation vehicle ECUs with the highest performing, lowest power offerings, while reducing their customers’ time to market and development costs by offering integrated and optimized production-proven solutions.”;
