Skewed-associative
WebbSkewed-associative caches have been shown to have two major advantages over conventional set-associative caches. First, at equal associativity degrees, a skewed-associative cache typically exhibits the same hardware complexity as a set-associative cache, but exhibits lower miss ratio. Webb在现代处理器中，Cache Block的组成方式大多都采用了Set-Associative方式。 与Set-Associative方式相关的Cache Block组成方式还有Direct Mapped和Fully-Associative两 …

Webb1 jan. 2005 · The skewed associative cache achieves a better average speedup at the cost of some pathological behavior that slows down four applications by up to 7%. View. Show abstract. WebbThis paper presents miss ratio performance and a dynamic power comparison for set-associative caches, a skewed cache and also for a new organization proposed, the elbow cache, which extends the skewed cache organization with a relocation strategy for conflicting blocks. The common approach to reduce cache conflicts is to increase the …
WebbA 64KB, 4-way set associative L1 instruction cache with 64-byte cache lines. A fully associative L1 instruction Translation Lookaside Buffer (TLB) with native support for 4KB, 16KB, 64KB, and 2MB page sizes. A 1536-entry, 4-way skewed associative L0 Macro-OP (MOP) cache, which contains decoded and optimized instructions for higher performance. WebbAs shown in Fig. 1, a skewed associative cache can be thought of as a set associative cache in which different hash functions are used to map memory items to different cache banks.
WebbWe have introduced skewed-associative caches to avoid this situation by scattering the data: mapping functions can be chosen such that whenever two lines of data conflict for … the whole being dead thing guitarIn a direct-mapped cache structure, the cache is organized into multiple sets with a single cache line per set. Based on the address of the memory block, it can only occupy a single cache line. The cache can be framed as a n × 1column matrix. Visa mer In a fully associative cache, the cache is organized into a single cache set with multiple cache lines. A memory block can occupy any of the cache lines. The cache organization can be … Visa mer Other schemes have been suggested, such as the skewed cache, where the index for way 0 is direct, as above, but the index for way 1 is formed with a … Visa mer Set-associative cache is a trade-off between direct-mapped cache and fully associative cache. A set-associative cache can be imagined as a n × mmatrix. The cache is divided into ‘n’ sets and each set contains ‘m’ cache … Visa mer A true set-associative cache tests all the possible ways simultaneously, using something like a content-addressable memory.
