The two companies are to assist developers in creating safety-critical solutions utilising RISC-V technology such as the AndesCore N25F-SE and D25F-SE.
In 2022, Andes Technology introduced the world’s first ISO 26262 fully compliant RISC-V processor IP, the N25F-SE and, since then, has developed an extensive portfolio of AndesCore processors catering for a diverse range of needs, from performance efficient MCUs to high-performance AI/ML computations.
To meet the demands of a wide range of automotive applications, Andes not only offers ASIL-B certified processor IPs but is also working on mission-critical ASIL-D certified processor IPs based on its CPU IPs. Andes Technology is shortly to release its next ISO 26262 fully compliant processor, the D25F-SE – the safety-enhanced D25F.
The D25F CPU IP is one of the most popular cores from the AndesCore 25-series and is equipped with RISC-V P-extension (SIMD/DSP) ISA draft to efficiently manipulate multiple data sets simultaneously in a single instruction.
Many endpoint applications processing digital signals such as voice, audio, image, and sensors as well as machine learning algorithms could get performance boost by the efficient SIMD/DSP instruction set. The AndesCore D25F-SE has already attracted some early customers, and is expected to become available in 2023 Q4 for general licensing.
WITTENSTEIN high integrity systems (WHIS), a safety systems company, produces and supplies real time operating systems (RTOS) and platform solutions. Its partnership with Andes Technology will allow RISC-V developers to use the RTOS SAFERTOS from WHIS with the latest AndesCore processors.
SAFERTOS has been independently certified by TÜV SÜD to IEC 61508 SIL3 and ISO 26262 ASIL-D and is delivered with full source code and Design Assurance Pack. It is tailored for the customer’s unique processor/compiler combination and has proved very popular due to its safety credentials and a straightforward upgrade path from the FreeRTOS, the industry’s most popular open-source RTOS.
“The functional safety AndesCore IPs offer unique and competitive value to our customers demanding RISC-V processors with full certification,” said Dr. Charlie Su, Andes Technology’s President and CTO. “This partnership with WITTENSTEIN high integrity systems enables us to provide solid solutions to our customers who are developing products for safety-critical applications.”
