Improve Your Kinetis Development

Let our extensive experience with the Cortex-M4 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.

Kinetis Optimizations

ThreadX optimizes context switching on the Kinetis processor. When context switching occurs inside of a ThreadX service call, only the registers preserved across function calls are saved as part of the thread's context, i.e. registers v1-v7, fp, and lr.

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 (registers a1-a4). The full register set is saved only if thread preemption is required.

Easy Mixed-Mode Programming

ThreadX fully supports the 16-bit Thumb and Thumb-II extensions of the Kinetis architecture. Using ThreadX, developers can freely build their applications in Thumb and/or traditional 32-bit mode.

Flexible FIQ Interrupt Handling

By default, ThreadX leaves FIQ interrupts alone. This results in zero FIQ interrupt latency. However, in this configuration application FIQ processing is not allowed to call ThreadX services. ThreadX can also be configured to provide complete FIQ-support, which provides the application FIQ handler access to ThreadX services.

Nested Interrupt Handling

ThreadX can also be configured to support nested interrupt handling - for both IRQ and FIQ interrupt sources.

Evaluation Board Support

ThreadX Evaluation Licenses are available for all Freescale Kinetis development systems.

Development Tool Choices

ThreadX is integrated with all the major ARM development tools, including ARM RealView, Wind River Workbench™, Green Hills MULTI, IAR Embedded Workbench, Lauterbach, and GNU. ThreadX-aware debugging is available with ARM's RealView, Wind River Workbench, IAR's Embedded Workbench, Lauterbach's TRACE32, and Green Hills MULTI.
