Abstract: In one embodiment of the present invention, a method includes switching between a first address space and a second address space, determining if the second address space exists in a list of address spaces; and maintaining entries of the first address space in a translation buffer after the switching. In such manner, overhead associated with such a context switch may be reduced.

Abstract translation: 在本发明的一个实施例中，一种方法包括在第一地址空间和第二地址空间之间切换，确定地址空间列表中是否存在第二地址空间; 并且在切换之后保持翻译缓冲器中的第一地址空间的条目。 以这种方式，可以减少与这种上下文切换相关联的开销。
