Computer Organization 4 Memory 不同的存储器组成存储体系。 为了解决CPU和主存速度不匹配的问题,我们在主存和CPU之间加入缓存,组成缓存-主存层次,这样大大提升了CPU调用信息的速度。主存和缓存之间的数据调动是由硬件控制的。在缓存-主存这一层次中,我们使用的是主存的物理地址,实际上,缓存是按内容访存的,不存在按地址
Cache memory exchange optimized memory organization for a computer systemData coherency in a multiprocessor system is improved and data latency minimized through the use of data mapping fill requests from any one of the multiprocessor CPUs such that the information requested is acquired through the ...
cache memory address is not in the use. Associative cache controller interprets the request by using the main memory address format. During the mapping process, the complete data block is transferred
In subject area: Computer Science An instruction cache refers to a small area of memory in a computer system that stores frequently used instructions. It is controlled by a set of functions that enable and disable the cache, as well as invalidate its contents. When the cache is invalidated, ...
In subject area:Computer Science A cache structure is a memory system that stores copies of data from main memory, allowing for faster access by the processor. It is organized in a hierarchy with different levels, each with varying access times and sizes, utilizing temporal and spatial locality...

Meanwhile, in order to hide memory access latency, a processor copies data in a memory to a cache memory (hereinafter also referred to as "cache") to use the data. In order to identify the address of data in the memory, a copy of which has been hold in the cache, in addition to ...
accesses of each processor in program order all accesses appear in sequential order 我理解就是简单说所有操作有一个全序,就所有操作偏序变全序。你可以用seq_cst来体验一下( 这个时候,写入要求: For each processor, delay start of memory access until previous one completes: each processor has only one ...
A cache memory organization is shown using a miss information collection and manipulation system to insure the transparency of cache misses. This system makes use of the fact that the cache memory has
The present invention provides a digital computer memory cache organization for efficient data logging, log-based copy and rollback, high-performance I/O, network switching and multi-cache consistency maintenance. The cache organization implements efficient selective cache write-back, mapping and transferr...
