Direct Mapped Scheme In a direct mapped cache, we treat the 128 slots as if they were an array of slots. We can index into the array using binary numbers. For 128 slots, you need 7 bits. Thus, the index of the array is from 0000000twoup to 1111111two. How do we decide which slot...

An initial scenario is that of direct-mapped caches and programs whose code and data just fit into the available memory space. Consider an instance of the placement problem in which all of the objects to be placed into memory have the same size, which is one-third of the cache size. This...
A cache line can be multidimensional (e.g., two or three or more dimensions) and may be viewed as an identifiable storage element in the cache. Memory may consist of a plurality of cache lines. Direct mapped cache may be utilized wherein each DRAM location maps to a single cache line....
Improving direct-mapped cache performance by the addition of a small fully-associative cache and prefetch buffers 阅读笔记 摘要 总结 摘要 计算机预测技术在不久的将来峰值将达到1000MIPS。如果这些处理器的层次结构基于传统的缓存技术,很容易损失一半甚至更多的性能。本文介绍了提高缓... ...

在上一节中讲过MappedByteBuffer VS FileChannel它们称得上零拷贝技术,但留下了顺序读比随机读快,顺序写比随机写快的问题,在我们的实际应用场景中为了回避随机读写需求,通常的做法都是对其进行文件分片(又将随机变成了有序),而本节借助Direct IO来彻底解决该问题。
