Mentor Nucleus RTOS extends system reliability for Arm Cortex v8-A 64-bit processors on multicore SoCs

Targets industrial, medical, automotive and airborne markets

  • Mentor extends the Nucleus® real-time operating system Process Model support to Arm® 64-bit processors on multicore system-on-chips (SoCs) designed for asymmetric and symmetric multiprocessing.
  • Nucleus Process Model is a lightweight and scalable framework that provides partitioned and protected memory regions for increased system reliability and safety for 32-/64-bit SoCs.
  • The process model facilitates software updates for individual modules, a key requirement for smart devices deployed in internet of things (IoT) systems.
  • This release of Nucleus also includes LWEXT 4 File System support for 64-bit systems requiring large files and/or journaling.

Jan 14, 2018 -  Mentor, a Siemens business, today announced the update of the  Nucleus® real time operating system (RTOS) targeting high-performance, next-generation applications based on 32- and 64-bit processors on multicore SoCs for industrial, medical, automotive, airborne, and IoT devices.  This Nucleus RTOS release extends the Nucleus Process Model to support asymmetric multiprocessing (AMP) and symmetric multiprocessing (SMP) on Arm® Cortex®v8-A processors and multicore SoCs.  The process model increases system reliability by isolating faults to individual software subsystems, preventing other software subsystems from being impacted.  Support for 64-bit processors and multicore SoCs allows developers to leverage the Nucleus Process Model for AMP and SMP designs on the latest 64-bit silicon. 

To meet the need for increased processing power and system consolidation, leading semiconductor manufacturers are delivering an array of heterogeneous multicore SoCs. The Nucleus Process Model provides the framework for embedded system developers to leverage cutting-edge multicore SoCs to meet performance requirements while increasing device reliability. The lightweight and scalable Nucleus Process Model increases system reliability by partitioning memory to create protected domains that isolate software subsystems in both kernel and user space without the overhead of memory virtualization. Other common use cases for the Nucleus Process Model include remote software updates for deployed IoT smart devices, and the ability to load and run only the applications needed in resource-constrained systems. 

“Embedded developers continue at an unprecedented rate to drive towards system consolidation with today’s complex heterogeneous SoCs,” stated Scot Morrison, general manager, Platforms Business Unit, Mentor Graphics Embedded Systems Division.  “Reducing design complexity with an operating platform that can meet both real time requirements and increase system reliability across an array of  32- and 64-bit cores found on today’s leading multicore SoCs is exactly what Nucleus was designed to address.”

This release includes support for the LWEXT 4 journaling file system with 64-bit, addressing maximum files sizes of 16 tebibytes. Nucleus ReadyStart includes 64-bit support for FAT and SAFE, a fault-tolerant files system for an array of media including NAND, NOR, RAM Disk, and eMMC.

The Sourcery™ CodeBench integrated development environment (IDE) platform comes with GNU debugger (GDB) and JTAG support using leading third-party probes and a pre-built, hardened, and supported GNU compiler collection (GCC) toolchain. The toolchain comes bundled with both aarch64 and aarch32 multilibs providing flexibility and choice to end users when working with Armv8-based processors.  The Sourcery CodeBench tool includes the  Sourcery Analyzer technology, a powerful embedded design analysis solution combining unique profiling and analysis engine with data visualization capabilities.

Nucleus ReadyStart is a comprehensive solution that includes support for a broad range of processor and architectures, including the NXP LS1046A and Xilinx Zynq® UltraScale+ MPSoCTM UltraZED-EG.
