IAR Systems, NSITEXE accelerate RISC-V functional safety development
Partnership will provide safety-certified RISC-V-based IP cores using IAR Embedded Workbench® development tools to further expand the possibilities for companies choosing RISC-V.

IAR Systems® has partnered with NSITEXE, a group company of DENSO Corporation that develops and sells high-performance semiconductor IP, to bring high-performance development tools with ensured functional safety and extensive support services to innovative applications based on RISC-V.

Functional safety is a constant growing requirement for embedded systems, with automotive applications, industrial automation and medical devices as three of the major driving forces. IAR Systems launched the first edition of its functional safety certified products in 2013. With the rise of RISC-V technology and its rapid evolution into many different embedded systems designs, functional safety is also becoming more and more important. In 2020, IAR Systems presented its functional safety products for RISC-V. IAR Systems and NSITEXE are now joining together to further expand the possibilities for companies choosing RISC-V.

NSITEXE was established in 2017 as a wholly-owned subsidiary of DENSO, one of the largest tier one automotive parts manufacturing companies, with significant development in key areas of advanced automotive technologies. Recently announced, the NS31A is a general-purpose CPU with a single-issue core with a 4-stage in-order pipeline that uses a 32-bit RISC-V ISA (RV32IMAF). It supports ISO 26262 ASIL D functional safety mechanism required for automotive applications, and also supports a privileged mode which is required by the  AUTOSAR Platform.

“At NSITEXE, development efforts have been focused on three pillars—versatility, efficiency, and functional safety—with massive future trends in mind,” commented Hideki Sugimoto, CTO, NSITEXE, Inc. ”The NS31A implements these as a RISC-V 32-bits general-purpose CPU with high functional safety for users who want to control embedded systems easily, reasonably, and safely. IAR Embedded Workbench® for RISC-V will be the must-use software development tools in the market of RISC-V, and IAR Embedded Workbench for RISC-V and NS31A will be a leading solution for customers who develop safety-related applications.”
