| PowerPC Optimizations | |||||||||||||||||||||||||
|
ThreadX optimizes PowerPC context switches. When a context switch occurs during a ThreadX service call, only the registers preserved across function calls are saved in the thread's context (r14-r31).
ThreadX also optimizes PowerPC interrupt handling. An interrupt service routine initially saves only the compiler's scratch registers (r0 and r3-r12). The full register set is saved only if the thread is preempted. | Improve Your PowerPC Development | ||||||||||||||||||||||||
