Improve Your Cortex-M3 Development
Let our extensive experience with the ARM Cortex-M3 microprocessor architecture 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.
Cortex-M3 Optimizations
ThreadX optimizes context switching on the Stellaris processors to take advantage of the SVC and PendSVC interrupts built into the Cortex-M3 architecture. This provides low interrupt latency and low overhead due to the unique “tail-chaining” capability of the Cortex-M3. As with all ThreadX versions, the full register set is saved only if thread preemption is required.
Nested Interrupt Handling
By default, ThreadX fully supports nested interrupt handling.
