| 68000 Optimizations | |||||||||||||||||||||||||||||||
| ThreadX optimizes context switching on the 68K. 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. This is typically registers a2-a6 and d2-d7.
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 (typically a0, a1, d0, and d1). The full register set is saved only if thread preemption is required. |
