Coldfire V1 CodeWarrior port

The Coldfire V1 CodeWarrior projects will not automatically update to later CodeWarrior versions unless all unnecessary files are deleted from the FreeRTOS/Source directory first. See this support thread for more information.

MSP430 CrossWorks and GCC demos

The CrossWorks demo has not yet been updated to use CrossWorks V2.0 or later. The GCC demo has not yet been updated to use the latest MSPGCC compiler version.

AVR32 demos

The IAR Embedded Workbench demos for the AVR32 will not currently build if you are using a later version of the IAR tool chain. The issue is caused by changes to macro names within the compiler header files.

ThreadX, developed and marketed by Express Logic of San Diego, California, United States, is a highly deterministic, embedded real-time operating system (RTOS) programmed mostly in the language C. Express Logic was purchased for an undisclosed sum by Microsoft on April 18, 2019.[1]

Overview[edit]

The author of ThreadX (and the original author of the Nucleus RTOS in 1990) is William Lamie,[2] who is President and CEO of Express Logic.

The name ThreadX is derived from the threads that are used as the executable elements, and the letter X represents context switching, i.e., it switches threads. ThreadX provides priority-based, preemptive scheduling, fast interrupt response, memory management, interthread communication, mutual exclusion, event notification, and thread synchronization features. Major distinguishing technology characteristics of ThreadX include preemption-threshold, priority inheritance, efficient timer management, fast software timers, picokernel design, event-chaining, and small size: minimal size on an ARM architecture processor is about 2 KB.

ThreadX supports multi-core processor environments via either asymmetric multiprocessing (AMP) or symmetric multiprocessing (SMP). Application thread isolation with memory management unit (MMU) or memory protection unit (MPU) memory protection is available with ThreadX Modules.

ThreadX has extensive safety certifications from Technischer Überwachungsverein (TÜV, English: Technical Inspection Association) and UL (formerly Underwriters Laboratories) and is Motor Industry Software Reliability AssociationMISRA C compliant.

ThreadX is the foundation of Express Logic's X-Ware Internet of things (IoT) platform, which also includes embedded file system support (FileX), embedded UI support (GUIX), embedded Internet protocol suite (TCP/IP) and cloud connectivity (NetX/NetX Duo), and Universal Serial Bus (USB) support (USBX). ThreadX has won high appraisal from developers and is a very popular RTOS.[3] As of 2017, according to marketing research firm VDC Research, the ThreadX RTOS has become one of the most popular RTOSes in the world, having been deployed in over 6.2 billion devices, including consumer electronics, medical devices, data networking applications, and SoCs.[4]

ThreadX is distributed using a marketing model in which source code is provided and licenses are royalty-free.

History[edit]

ThreadX was first introduced in 1997. ThreadX 4 was introduced in 2001. ThreadX 5 was introduced in 2005, and is the latest version as of 2020.

FileX – the embedded file system for ThreadX was introduced in 1999.

NetX – the embedded TCP/IP networking stack for ThreadX was introduced in 2002.

USBX – the embedded USB support for ThreadX was introduced in 2004.

ThreadX SMP for SMP multi-core environments was introduced in 2009.

ThreadX Modules was introduced in 2011.

ThreadX achieved safety certifications for: TÜV IEC 61508 in 2013, and UL 60730 in 2014.

GUIX – the embedded UI for ThreadX was introduced in 2014.

Express Logic was purchased for an undisclosed sum by Microsoft on April 18, 2019.[1]

Technology[edit]

ThreadX implements a priority-based, preemptive scheduling algorithm with a proprietary feature called preemption-threshold. The latter has been shown to provide greater granularity within critical sections, reduce context switches, and has been the subject of academic research on guaranteeing scheduling.[5]

ThreadX provides a unique construct called event chaining,[6] where the application can register a callback function on all application programming interfaces (APIs) that can signal an external event. This helps applications chain together various public objects in ThreadX such that one thread can effectively block on multiple objects.

ThreadX also provides counting semaphores, mutexes with optional priority inheritance, event flags, message queues, software timers, fixed sized block memory, and variable sized block memory. All APIs in ThreadX that block on resources also have an optional timeout.

ThreadX offers multi-core processor support via either AMP or SMP. Application code isolation is available through ThreadX Modules component.

Major components[edit]

ThreadX RTOS components include:

  1. Embedded file system
  2. Embedded graphical user interface
  3. Embedded networking
  4. Embedded USB
  5. Safety certification
  6. Packaging

Embedded file system[edit]

FileX is the embedded file system for ThreadX. FileX supports FAT12, 16, 32, and exFAT formats. The latter extends FAT file sizes beyond 4 GB, which is especially useful for video files, and it requires license directly from Microsoft for use. FileX also offers fault tolerance and supports direct NOR and NAND flash memory media through a flash wear leveling product called LevelX.

Embedded graphical user interface[edit]

GUIX is the embedded graphical user interface (GUI) for ThreadX. GUIX provides a 2D runtime system (environment) for embedded applications running ThreadX. GUIX supports multiple display devices with a variety of screen resolutions and color depths. Many predefined graphical widgets are available. A Windows WYSIWYG host tool called GUIX Studio automatically generates C code for GUIX to execute at runtime.

Embedded networking[edit]

NetX Duo is the embedded TCP/IP system for ThreadX. NetX Duo supports both IPv4 and IPv6 networking along with protocols such as ARP, Auto IP, DHCP, DNS, DNS-SD, FTP, HTTP, ICMP, IGMP, mDNS, POP3, PPP, PPPoE, RARP, TFTP, SNTP, SMTP, SNMP, and TELNET. IP layer network security is provided by IPsec. TCP and UDP socket layer security is provided by TLS and DTLS, respectively. IoT Cloud protocol support includes CoAP, MQTT, and LWM2M. NetX Duo also supports Thread and 6LoWPAN. In 2017, ThreadX and NetX Duo became a Thread Certified Product.[7]

Embedded USB[edit]

USBX is the embedded Universal Serial Bus (USB) system for ThreadX. USBX supports both host and device. Host controller support includes EHCI, OHCI, and proprietary USB host controllers. USBX also supports OTG. USBX class support includes Audio, Asix, CDC/ACM, CDC/ECM, DFU, GSER, HID, PIMA, Printer, Prolific, RNDIS, and Storage.

Safety certification[edit]

ThreadX (and FileX and NetX Duo) have been precertified by SGS-TÜV Saar to the following safety standards:IEC 61508 SIL 4, IEC 62304 Class C, ISO 26262 ASIL D, and EN 50128 SW-SIL 4.

ThreadX (and FileX and NetX Duo) have been precertified by UL to the following safety standards: UL/IEC 60730, UL/IEC 60335, UL 1998

ThreadX has also been certified to DO-178 standards by various military and aerospace companies. It is supported by popular Transport Layer Security (SSL/TLS) libraries such as wolfSSL.[8]

Packaging[edit]

As of 2017, ThreadX is packaged as part of X-Ware IoT Platform in full source code and with no runtime royalty payment.

Products using it[edit]

Some high-profile products using ThreadX range from small wearable devices, to Hewlett-Packard printers, and even NASA’s Deep Impactspace probe.[9]

Threadx Open Source

The Raspberry Pi line of one-board personal computers runs ThreadX as a binary blob on the graphics processing unit (GPU). This controls initial booting, which in turn is used to boot secondary operating systems such as Linux, and continues to operate in a more privileged role even after the boot process.[10]
