Abstract

The authors define and evaluate the continuity distribution in memory mapping of some typical benchmark programs, and verifiy the existence of multiple types of continuity (mixed continuity) in memory mapping of programs. Furthermore, some technologies using continuity of memory mapping to improve translation coverage of TLB are evaluated. It is found that the existence of mixed continuity limits the actual effect of existing technologies in real scenes.
