Translation Lookaside Buffers (TLBs) are critical to processor performance. Much past research has ad-dressed uniprocessor TLBs, lowering access times and miss rates. However, as chip multiprocessors (CMPs) become ubiquitous, TLB design must be re-evaluated. This paper is the first to propose and evaluate shared

This can lead to distinct TLBs for each access type, an instruction translation lookaside buffer (ITLB) and a data translation lookaside buffer (DTLB). Various benefits have been demonstrated with separate data and instruction TLBs. [4] The TLB can be used as a fast lookup hardware cache. The figure shows the working of a TLB.

Specifically, MIG partitions the L1 and L2 TLBs along with the GPCs: the L1 TLB is shared between the two SMs within each Texture Processing Cluster (TPC), and the L2 TLB is

the hit rate benefits of shared TLBs at the access latency of private TLBs via the following features: 1 High capacity: NOCSTAR offers higher hit rates than private L2 TLBs by eliminating replication and improving utilization. 2 Low lookup latency: NOCSTAR achieves low lookup la-tency by replacing a monolithic shared L2 TLB structure with

data Translation Lookaside Buffers (TLBs). While there are a number of options for TLB placement and lookup [13], most systems place them in parallel with the first-level cache, effectively inserting them in the critical path of pro-cessor pipelines. As a result, TLBs play a crucial role in processor performance [4, 11, 12, 14].

2019年6月22日 · This paper focuses on a new attack vector in modern processors: the timing-based side and covert channel attacks due to the Translation Look-aside Buffers (TLBs). This paper first presents a novel three-step modeling approach that is used to exhaustively enumerate all possible TLB timing-based vulnerabilities.

Much past research has addressed uniprocessor TLBs, lowering access times and miss rates. However, as chip multiprocessors (CMPs) become ubiquitous, TLB design must be re-evaluated.

2018年3月30日 · 使用tlbs时，当在进程之间切换时出现了一些新的问题(也就是地址空间)。特别地，tlb包含了对当前正在运行的进程有效的虚拟到物理翻译;这些翻译对其他过程没有意义。

2017年5月25日 · In this paper, we present a survey of techniques for architecting and managing TLBs. We characterize the techniques across several dimensions to highlight their similarities and distinctions.
