Improving TLB performance
In modern computers, TLB can be in the critical path of a memory access. Good TLB performance is essential to good overall performance of a machine 5]. The objective of our project is to improve the TLB performance. In our project, we propose two approaches to improve TLB performance. One approach is to use TLB prefetching, and the other is to have an additional level TLB (so we have a multi-le...
متن کامل8. Algorithms for Hardware Caches and TLB
Over the last 20 years or so CPU clock rates have grown explosively, and CPUs with clock rates exceeding 2 GHz are now available in the mass market. Unfortunately, the speed of main memory has not increased as rapidly: today’s main memory typically has a latency of about 60 ns. This implies that the cost of accessing main memory can be 120 times greater than the cost of performing an operation ...
متن کاملItanium Page Tables and TLB
The Itanium architecture offers considerable flexibility in managing the TLB. Besides features found in many architectures, such as TLB tags and superpages, it supports two quite unusual features. One is the choice of two hardware-walked page table formats, a linear array and a hashed page table. The other is an unusual TLB tagging scheme which, among others, allows a single TLB entry to map a ...
متن کاملTLB Performance in Multiprocessors by Patricia
This paper compares the performance, in highly-parallel shared-memory multiprocessors, of locating translation-lookaside buffers (TLBs) at processors with that of locating TLBs at memory. Our performance comparison is based on results of trace-driven simulations of multiprocessors with logN-stage networks interconnecting N processors and N memory modules. For the systems and workloads studied, ...
متن کاملEnhancing TLB Reach with Ternary-CAM Cells
Anuj Kumar and Rabi N Mahapatra Department of Computer Science Texas A&M University, College Station, TX 77843 {anujk,rabi}@cs.tamu.edu Abstract In this paper, we propose dynamic aggregation of virtual tags in TLB to increase its coverage and improve the overall miss ratio during address translation. Dynamic aggregation exploits both the spatial and temporal locality inherent in most applicatio...
