存管理了。然后通过一个个的mapping,最后落得某一个包厢(Set)的长凳子(Way) 上。 这样OS与CPU之间的语义就存在了一定程度的Aware了。 下图所示为在上几节中,given 一个2M的4Way SET-Assoc L2 Cache,4K的物理Page的case study中,Cache Bin的分布情况illustration: 浅谈高端CPU的Cache Coloring(5) 上几节中,...
A computer system can unify main memory and cache memory, wherein fully associative mapping method can be utilized to cover a whole range of cache and main memory. In the system, central processing unit (CPU) sends a data request and access the cache portion of the unified cache and memory...
A diagram of the architecture and data flow of a typical cache memory unit. Cache memory mapping Caching configurations continue to evolve, but cache memory traditionally works under three different configurations: Direct mapped cachehas each block mapped to exactly one cache memory location. Conceptual...
在许多实现中,Set Selection时选用的pseudo-random算法等效于Hash算法,这些Hash算法多基于XOR-Mapping机制,需要几个XOR门级电路即可实现。诸多研究表明[23][28][29],这种算法在处理Cache Conflict Miss时优于Bit Selection。 在已知的实现中,追求Hit Time的L1 Cache很少使用这类Hash机制,但是这些方法依然出现在一些处理...
Abstract:In order to improve the unified shading processor efficiency of the mobile graphics processor and reduce the number of accesses between it and the off-chip memory, this paper presents a four-port texture cache architecture. This architecture uses texture mapping based on Mipamp algorithm an...

It is for this reason that virtual memory is described as a mapping between two namespaces; one must remember this when dealing with virtual caches. As long as there is a one-to-one mapping between data and names, no inconsistencies can occur, and the entire virtual memory mechanism behaves...
Direct mapping: An I-cache is a mapping of memory addresses to contents; the mapping is usually implemented by a simple hash function that optimizes for the case of sequential access. Thus most processors use direct-mapped I-caches, where the low-order bits of a memory address are used to...
