=-=[19]-=- proposed a profile-based technique to partition the virtual pages to different caches. Their algorithm has complexity O(m 3 n), where m is the number of pages accessed in the application, and n is th...Using Cache Mapping to Improve MemoryPerformance Handheld Devices". X. ...
In this paper, an efficient technique is proposed to manage the cache memory. The proposed technique introduces some modifications on the well-known set associative mapping technique. This modification requires a little alteration in the structure of the cache memory and on the way by which it can...
The maximum memory access bandwidth is 10.512 GB/s. Key words : array processor;reconfigurable;storage structure;distributed Cache;parallelism 0 引言 随着电路技术飞速发展,人工智能等新应用层出不穷,可重构阵列处理器[1-2]兼顾通用处理器(General Purpose Processor,GPP)[3]灵活性和专用集成电路(Application ...
Generally, here are three cache mapping techniques to choose from: Direct-mapped cache.It’s the simplest technique, as it maps each memory block into a particular cache line. Fully-associative cache.This technique lets any block of the main memory go to any cache line available at the moment...

The solution is to have the operating system attempt to assign different physical color pages to different virtual colors, a technique called page coloring. Although the actual mapping from virtual to physical color is irrelevant to system performance, odd mappings are difficult to keep track of and...
