Andes Technology, a leading supplier of high-efficiency, low-power 32/64-bit RISC-V processor cores, today announced the launch of its new  D23-SE  core, a compact and secure processor designed for functional safety applications. Based on the production-proven  D23, the  D23-SE  is engineered to meet the stringent safety and performance requirements of  ASIL-B and ASIL-D  automotive systems.

The D23-SE brings advanced safety mechanisms to the RISC-V ecosystem, including  Dual-Core Lockstep (DCLS) and Split-Lock operation. These features allow the core to operate in the lockstep mode for the most safety-critical tasks, or independently in the split mode for increased system flexibility and performance efficiency with moderate safety requirements. The dual-mode support enables developers to balance performance and safety based on real-time requirements.

In addition to its functional safety capabilities, the 32-bit D23-SE supports RISC-V’s latest ISA extensions to offer the most compact code size and speed up common crypto algorithms such as AES, SM and SHA by up to 7 times. It establishes a strong foundation for hardware isolation through its enhanced PMP and integration with Andes’ dedicated I/O Memory Protection Unit. With the solid security and safety features, the D23-SE enables a wide range of automotive and industrial applications, from control and monitoring systems to intelligent edge computing. It also maintains the same outstanding 4.55 Coremark/MHz as the D23.

“With the introduction of the D23-SE, Andes continues its commitment to delivering industry-leading RISC-V processors for safety-critical applications,” said Dr. Charlie Su, President and CTO of Andes Technology. “The D23-SE enables customers to accelerate ISO 26262 certification and shorten time-to-market for their ASIL-compliant designs.”

The D23-SE is the latest addition to Andes’ growing family of functional safety cores, joining the N25F-SE, D25F-SE and high-performance D45-SE. All Andes functional safety processors are developed in accordance with ISO 26262 process and come with a comprehensive safety package.
