Improve Your CEVA-TeakLite-III Development

Let our extensive experience with the CEVA-TeakLite-III 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.

CEVA-TeakLite-III Optimizations

ThreadX optimizes context switching on the CEVA-TeakLite-III. 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. 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. The full register set is saved only if thread preemption is required.

Flexible Interrupt Model

ThreadX supports the variety of shadow register options on the CEVA-TeakLite-III as well as the stack-based register architecture of the CEVA-TeakLite-III. All interrupt processing uses a separate system stack and as mentioned previously, full context saving/restoring is performed only when thread preemption is necessary.
