A statistical model of skewed-associativity

A New Case for Skewed-Associativity

Skewed-associative caches have been shown to statisticaly exhibit lower miss ratios than set-associative caches at equal associativity degrees. But for L1 caches, the performance of a four-way set-associative cache is known to be quite close to that of a 16-way set-associative cache. In this paper, we rst show that BTBs and L2 caches featuring long line size may beneet a lot from a high associa...

Highly Efficient LRU Implementations for High Associativity Cache Memory

High associativity with replacement policy as LRU is an optimal solution for cache design when miss rate has to be reduced. But when associativity increases, implementing LRU policy becomes complex. As many advance and demanding technologies like multimedia, multithreading, database and low power devices running on high performance processors in servers and work stations use higher associativit...

A New Case for Skewed - Associativity André Seznec

Trade-offs for Skewed-Associative Caches

The skewed-associative cache achieves low miss rates with limited associativity by using inter-bank dispersion, the ability to disperse blocks over many sets in one bank if they map to the same set in another bank. This paper formally defines the degree of inter-bank dispersion and argues that high inter-bank dispersion conflicts with common micro-architectural designs in which the skewed-assoc...

On Burr III-Inverse Weibull Distribution with COVID-19 Applications

We introduce a flexible lifetime distribution called Burr III-Inverse Weibull (BIII-IW). The new proposed distribution has well-known sub-models. The BIII-IW density function includes exponential, left-skewed, right-skewed and symmetrical shapes. The BIII-IW model’s failure rate can be monotone and non-monotone depending on the parameter values. To show the importance of the BIII-IW distributio...
