Improve Your XScale Development
Let our extensive experience with the XScale 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.
XScale Optimizations
ThreadX optimizes context switching on the XScale. 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 extensions of the ARM 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 demonstrations are available for all major evaluation platforms.
Development Tool Choices
ThreadX is integrated with all the major ARM development tools, including ARM RealView, IAR, GNU, Lauterbach, Metrowerks, MetaWare, EPI, and Green Hill's MULTI. Additional ThreadX-aware debugging is available with ARM's RealView, IAR's C-SPY, Lauterbach's TRACE32, and Green Hills MULTI.
