RTOS

DigiKey is providing a free, on-demand Zephyr RTOS online workshop and video series. Aimed at students and engineers, you learn how to write a Zephyr device driver. Zephyr is real-time operating system (RTOS) and development framework, an open source project at the Linux Foundation. DigiKey identifies a steep learning curve, but says Zephyr is a key system for engineers and ...

Ambiq has ported Zephyr RTOS to several of its Arm Cortex-M based microcontrollers. Initially Apollo3 (Corex-M4), Apollo4 Plus (M4), Apollo4 Blue Plus (M4 + Bluetooth) and the upcoming Apollo510 (Cortex-M55) will be covered. “Embedded developers, already working within the Zephyr environment, can easily port their software to Ambiq’s chips to take advantage of the much lower power consumption,” according to ...

Arduino is transitioning from using ARM's Mbed IoT platform to the open source ZephyrOS RTOS (real-time operating system).

Green Hills Software announced support for NXP’s S32G3 vehicle network processor at Embedded World in Nuremberg today. “This combines connected-car middle-ware with essential foundational software that includes safety and security-certified MPU and MCU real-time operating systems, secure virtualisation and an integrated development environment,” said Green Hills. “The combination of the S32G3 processors with real-time operating systems like Integrity and µ-velOSity ...

IAR Systems has added PX5 RTOS support to its Embedded Workbench for Arm development tool suite – a development tool-chain with a C/C++ compiler and debugging. “The PX5 Industrial RTOS is an advanced 5th-generation RTOS designed for the most sophisticated and developed embedded applications, and is deterministic regardless of system load,” said IAR. It “helps embedded systems developers to manage the ...

Renesas is aiming at applications that need a fast RTOS (real-time operating system) as well as a sophisticated user interface with a group of microcontrollers built around a single 1GHz 64bit Arm Cortex-A55 core. RZ/A3UL MCUs, as they will be known, are intended to boot FreeRTOS or Azure RTOS within one second. “This feature is ideal for systems that require ...

Unikernel is a technology that potentially combines the benefits of virtualisation and containerisation. Ian Ferguson, at Lynx Software Technologies, believes the time for unikernel is now. Unikernel technology has existed since at least 2016, but it has not been widely adopted, even in secure mission critical applications where it potentially offers the greatest benefits. While the technology still is not ready ...

The European Space Agency has qualified the RTEMS open-source real-time operating system for safety-critical multi-processing in satellites. Railway, medical and automotive sectors could benefit. “ESA certified RTEMS in the symmetric multiprocessing configuration for Criticality Category C and D,” said German RTEMS support company Embedded Brains. “This means that safety-critical functions can now also be executed on modern multicore processors that ...

Congatec and RTOS company Sysgo have teamed up to provide Arm and x86 platforms tailored for functional safety and cybersecurity requirements. “This cooperation makes great sense for both partners, now that the latest platforms from NXP and Intel make it possible to develop functional safety-critical systems without additional hardware,” said Congatec marketing director Christian Eder. First implementations, certifiable in appropriate ...

Segger has eliminated periodic tick interrupts in an RTOS, replacing the typically 1ms system tick with a single-shot hardware timer that generates interrupts when, and only when, necessary, it said. Dubbing the technique ‘cycle-resolution timing’, “scheduling of all time-based events, such as time-outs, delays and periodic timers, can now be specified in microseconds or CPU cycles”. It “replaces ad-hoc, target-specific techniques for ...
