现代计算机架构设计,经过多年的发展和演化,沉淀了很多重要的思想,其中一个便是“层次化”,而Cache就是这种思想的一种很好的体现。以Cache为主体的memory hierarchy,在现代计算机架构中是名副其实的“半边天”。此外,了解Cache,不仅对了解CPU、GPU有重要的意义,对了解Linux Kernel也很有参考价值,此外,对Cache深入的理...
processor 写到了 write-buffer 里,而网卡可能没有读到 buffer 中的数据,而是读到了 memory 中的 stale data,造成写 stale data 网络中数据写到了 memory 中,通知 processor, processorlw读到了 cache,造成读 stale data 某种意义上说,这也是一种不一致导致的,为了解决这个问题,需要下列的支持 CPU 写的时候可以...
A cache-based computer architecture is disclosed in\nwhich the address generating unit and the tag comparator\nare packaged together and separately from the cache\nRAMs. If the architecture supports virtual memory, an\naddress translation unit may be included on the same\nchip as, and logically ...
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 a faster rate of operation than the rate of operation of central memory. The cache memory cons...
of cache; it might have 1 or 2 level of cache. At the core level is cache of first level that isL1 cache memory. The commonly used commands/instructions/data is stored in this section of memory. This is built in the processor itself. Thus this is fastest of all the cache memory. ...
Cache conscious data layout organization for embedded multimedia applications Cache misses form a major bottleneck for real-time multimedia applications due to the off-chip accesses to the main memory. This results in both a major ac... C Kulkarni,C Ghez,M Miranda,... - 《IEEE Transactions on...
数据控制公司(control data corporation)于1980 年提出专利号为4370710,名称为“Cache memory organization utilizing miss information holding registers to prevent lockup from cache misses”的专利申请 [4] 。该专利的被引证52 次。该申请提出Nonblocking Cache 的思想和实现方法。如图4 所示: 图4 专利号为4370710...
I´m looking for the knowledge of cache system organization on I7 processors. If any Intel developer can help me I should like to know: The type of organization of the different levels of cache, i.e., if they are associative, direct mapped or N set associative. The answer in clock cy...
