Direct Mapping k-way set Associative Mapping 中 k = Total number of lines in the cache,也就是只存在一个set,地址映射时不存在set num这个区域。 那么tag其实不存在了,只需要line number就可以确定cache中的位置。 Fully Associative Mapping k-way set Associative Mapping 中 k =1, 也就是每个set中的li...

Direct Mapped Cache is a cache organization where each set contains only one block. Memory addresses are mapped onto cache blocks in a direct manner, with each address mapping to exactly one set in the cache. AI generated definition based on: Digital Design and Computer Architecture (Second Edit...
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 ...
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...

IV. CACHE CONTROLLER MAPPING Cache memory plays a crucial role in enhancing computer system performance by bridging the gap between the high-speed central processing unit (CPU) and the slower main memory. One of the key decisions in cache design is how memory addresses are mapped to specific ca...
For example, reading 300,000 lines of memory addresses will take a long time when using a fully associative mapping. Any optimization assistance is welcome. The program is written in standard C++ without third-party dependencies and supports Windows, Linux, and MacOS. It uses some classes from ...
