At the point when data are fetched from the main memory, it is checked if neighboring cache lines have the same tag bits as those of the data fetched. This same tag bit information is stored in the cache as additional bits to be utilized later. At the point when an error is recognized...

Direct Mapped Cache A direct mapped cache has one block in each set, so it is organized into S = B sets. To understand the mapping of memory addresses onto cache blocks, imagine main memory as being mapped into b-word blocks, just as the cache is. An address in block 0 of main memo...
A cache is organized into S sets, each of which holds one or more blocks of data. The relationship between the address of data in main memory and the location of that data in the cache is called the mapping. Each memory address maps to exactly one set in the cache. Some of the addre...

The flags parameter should be set to DDI_DMA_STREAMING for memory transfers that are sequential, unidirectional, block-sized, and block-aligned. This type of access is commonly known as streaming access.In some cases, an I/O transfer can be sped up by using an I/O cache. I/O cache ...
直接访问(Direct Access,DAX) 机制是一种支持用户态软件直接访问存储于持久内存(Persistent Memory,PM) 的文件的机制,用户态软件无需先将文件数据拷贝到页高速缓存(Page Cache)1。 上述描述对应到下面这张图(Typical NVDIMM Software Architecture2)中,就是说(File)和(Memory)这两条 IO 路径都能绕过页高速缓存。
最近遇到一个 netty 的 OutOfDirectMemoryError 报错,是在分配 direct memory 时内存不足导致的,看了下报错提示,要分配的内存大小为 16M,剩余的空间不足。这里 max direct memory 大约有 7G,于是就有一个疑问,这个值是怎么设置的? 代码分析 这里使用的 netty 版本是 4.1.14.Final,如下是报错时的调用栈信息,主...
