Improve Your Embedded Development

Let our extensive experience with the Freescale ColdFire family of microprocessors help your product development. ThreadX, our high-performance real-time kernel, helps improve your product's quality and its time-to-market. In addition, using ThreadX makes it easier to enhance your product in the future.

ColdFire Family Optimizations

ThreadX optimizes context switching. When context switching occurs inside of a ThreadX service call, only the registers preserved across function calls are saved. This is typically registers a2-a6 and d2-d7.

A similar technique is used in interrupt handling. On the front end of interrupt service routines, only the compiler's scratch registers are saved initially (typically a0, a1, d0, and d1). The full register set is saved only if thread preemption is required.

Easy to Use

ThreadX is designed for ease of use. Our API is designed to be easy to understand, powerful, and consistent. The same is true with our documentation!

Development Tool Choices

ThreadX is completely compatible with all the major ColdFire and 68K development tools, including Metrowerks CodeWarrior, Diab, GNU, visionCLICK, SingleStep, and Green Hills MULTI development tools. Additional ThreadX-aware debugging is available with the CodeWarrior, visionCLICK, SingleStep, and Green Hills MULTI.
