ThreadX

Real-Time Operating System (RTOS)

Express Logic’s ThreadX RTOS gives device developers using i.MX, PowerPC, or ColdFire the

ability to employ a small, fast RTOS to provide real-time multithreading services in consumer,

industrial and networking devices. Working with the developer’s compiler and debugger of

choice, ThreadX makes software development fast and easy. ThreadX is provided in full source

code, and may be evaluated free of charge.

ThreadX is a small-footprint, low-overhead, royalty-free real-time operating system (RTOS). It

is ideally suited for high-volume resource constrained applications, including memory size and

processor speed. ThreadX resides in under 10KB of ROM, and uses less than 2KB of RAM.

Minimal configurations can be as small as 2KB ROM.

ThreadX provides basic preemptive scheduling for application threads, and runs all threads

in a single linear address space for ease of programming and maximum performance.

ThreadX has an intuitive and easy-to-use API, with 61 services for thread management, inter-

thread communication, resource sharing, timer management, memory allocation and event

synchronization. ThreadX handles interrupts with minimal latency, and performs rapid context

switching. ThreadX offers a unique service called “preemption-threshold™” that enables

establishment of a minimum priority level for preemption on a thread-by-thread basis.

ThreadX is complemented by Express Logic’s NetX™ TCP/IP stack that supports IPv4.IPv6 dual

mode operation, its FileX

FAT-compatible embedded file system, its USBX™ USB host/device

stack, and its PEGX™ GUI development kit. All Express Logic products are licensed in full

source code form and are completely royalty-free. Production licenses start at just $12,500.

Freescale and Express Logic

ThreadX runs on all i.MX, ColdFire and PowerPC processors. ThreadX is supported by

Freescale CodeWarrior, ARM RealView, IAR Embedded Workbench, Wind River Workbench,

and Green Hills Software MULTI development tools.
