摘要：
A system and method for performing an emulation context switch save and restore in a processor that executes host applications and emulates guest applications. The processor includes an operating system and a first register that is saved and restored by the operating system during a host application context switch. The method and system comprises renaming the special-purpose register to the first register when emulating guest applications. When an emulation context switch occurs, a context save and restore of the special-purpose register is performed through the first register without operating system modification.
