Express Logic, a leader in royalty-free real-time operating systems (RTOSes), announced that it plans to join the ARM mbed ecosystem for Internet of Things (IoT) product development. ARM mbed OS is an operating environment for IoT devices and is especially well-suited to run in energy constrained applications. mbed OS includes the connectivity, security and device management functionalities required in every IoT device. Express Logic’s ThreadX RTOS, and NetX Duo IPv6 network stack will complement mbed OS with full real-time RTOS capabilities and advanced Networking technology for IoT networked applications seeking robust RTOS functionality.
mbed OS includes a basic, non-preemptive scheduler with limited synchronization and communication primitives, to support the communication and cloud protocols of mbed OS. ThreadX provides a solution for IoT developers who need priority-based, fully-preemptive scheduling capabilities plus all the additional services of a commercial RTOS. ThreadX also brings round-robin scheduling, Preemption-Threshold Scheduling, priority inheritance, event-chaining, event-trace, run-time stack analysis, and completely deterministic processing.
For devices requiring safety certification, ThreadX was the first RTOS to earn UL/IEC 60730 safety certification and also offers TUV IEC 61508 and IEC 62304 certification for Medical, Industrial, and transportation, and DO-178B certification for Avionics. With the addition of ThreadX, the mbed OS community will be able to leverage all of Express Logic's X-Ware middleware products as well, including the FileX file system, GUIX graphics framework, NetX Duo TCP/IPv4/IPv6 network stack, USBX USB host/device/OTG stack and TraceX real-time event trace analysis tool.
"Our ThreadX® RTOS complements the ARM mbed OS platform by adding full RTOS multitasking and services for real-time applications," said William E. Lamie, president of Express Logic. “IoT devices by their very nature have complex networking requirements. Developers need a complete and easy to use IPv6 TCP/IP stack to meet the challenges of the ‘connected’ network. Express logic’s NetX Duo™ provides both IPv4 and IPv6 functionality and the ability for developers to configure their interface addresses automatically through its Stateless Address Autoconfiguration protocol. ThreadX already is widely used by developers of ARM-based IoT systems, including IoT developers using Broadcom's WICED and Gainspan's GS2000 SoC’s, both of which are based our proven X-Ware solutions. We are excited to extend these already proven IoT solutions to the mbed OS development community.”
