摘要

越来越多的体系结构通过软件管理的tlb提供虚拟内存支持。然而，软件管理可能会施加相当大的惩罚，这些惩罚高度依赖于操作系统的结构及其对虚拟内存的使用。这项工作探讨了软件管理的TLB设计权衡及其与一系列单片和微内核操作系统的交互。通过硬件监控和仿真，我们探索了在基于MIPS r2000的工作站上运行Ultrix、OSF/1和三个版本Mach 3.0的基准测试的TLB性能。

Design Tradeoffs For Software-managed Tlbs

An increasing number of architectures provide virtual memory support through software-managed TLBs. However, software management can impose considerable penalties that are highly dependent on the operating system's structure and its use of virtual memory. This work explores software-managed TLB design tradeoffs and their interaction with a range of monolithic and microkernel operating systems. Through hardware monitoring and simulation, we explore TLB performance for benchmarks running on a MIPS R2000-based workstation running Ultrix, OSF/1, and three versions of Mach 3.0.
