Mentor Graphics adds 64-bit ARMv8-A support to Nucleus RTOS

WILSONVILLE, OR. Mentor Graphics has announced 64-bit ARMv8-A processor support on its Nucleus real-time operating system (RTOS), while also enabling the ARMv8-A aarch32 execution mode that allows legacy 32-bit code on 64-bit system on chips (SoCs). ARMv8-A support has also been integrated in Mentor’s Nucleus ReadyStart, a platform package that includes the Sourcery CodeBench Eclipse-based IDE, Sourcery Analyzer visualization tools, a GNU compiler collection (GCC) toolchain with aarch64 and aarch32 multilibs, the complete Nucleus RTOS source code, and integrated support for ARM DSTREAM on NXP’s QorIQ LS2085.

The Nucleus RTOS has been ported to the NXP QorIQ LS2085A-RDB Reference Design Board, with support current available for kernels including NEON, Nucleus Process Model, CPU, and UART. This architecture port can also support related SoCs in NXP’s QorIQ LS208x, LS204x, LS208x, LS108x, LS104x, and LS101x processor families, and be extended to other ARMv8-A SoCs by customers or Mentor Embedded professional services.
