在x86 架构的Cache 光谱线上,有 read 和 write 都 cache 的 Writeback 模式(简称 WB),有 read 时 cache,write hit 时同步写入 cache line 和 main memory,而 write miss 时不分配 cache line(即没有 write allocate),直接写入 memory 的 Writethrough 模式(简称 WT)。 图-1 而上图绿框的这个代表 Write...
Memory) Write Through(WT) 讀寫的動作都可以被 Cache。寫入的動作必須同時寫入到 Cache 以及系統記憶體中 Write Back(WB) 讀寫的動作都可以被 Cache。寫入的動作只寫入到 Cache,只有當 Cache line 要移除時,才執行寫回到系統記憶體的動作。此種方式可以達到最高的執行效率。 Write Protected(WP) 只有讀的動作...
A write transaction includes a data block, which is a part of the output tensor, and metadata describing one or more attributes of the data block. The WCB may store write transactions in its internal buffers. The WCB may determine whether to combine two write transactions, e.g., based on...

WhileK6INITcan run completely autonomously, it supports manual, detailed control overMemory Type Range Registers(including Write-Combine and Cachability modes),Write Allocate,Write Ordering,CPU CacheandFrequency Multiplier. In contrast to other tools,K6INITcan be loaded fromCONFIG.SYS, so it works eve...

Read each pair of sentences carefully.Then combine them in two different ways,once with too,and once with enough.仔细读每组中的两个句子,然后用两种不同的方式将他们连成一句:一种用too,一种用enough. Example: That game is very fast.I'm not quick enough,so I can't play it. You write: I...
