The proposed method empowers L2 cache to work in an equal direct mapping manner. This leads to significant energy reduction without performance degradation. If the error identified in the location of L2 cache it should correct the error using same tag bit information. At the point when data ...

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 memory maps to set 0...
3. Understanding Direct-Mapped Cache In the direct mapping scheme, we map each block of main memory to only one specific cache location. In this scheme, memory blocks are mapped to cache lines using a hashing or indexing mechanism. When accessing the main memory address, we consider its three...
A cache is a small, fast array of memory placed between the processor and main memory. It is a holding buffer that stores portions of recently referenced system memory. The processor uses cache memory in preference to system memory whenever possible to increase averagesystem performance. ...

Cache devices must be 32 GB or larger. Persistent memory devices are used in block storage mode. When using persistent memory devices as cache devices, you must use NVMe or SSD capacity devices (you can't use HDDs). If you're using HDDs to provide storage capacity, you must use...
同时我们可以通过-XX:MaxDirectMemorySize来指定最大的堆外内存大小,当使用达到了阈值的时候将调用System.gc()来做一次full gc,以此来回收掉没有被使用的堆外内存。 堆外内存那些事 使用堆外内存的原因 对垃圾回收停顿的改善 因为full gc 意味着彻底回收,彻底回收时,垃圾收集器会对所有分配的堆内内存进行完整的扫...

Direct mapping: An I-cache is a mapping of memory addresses to contents; the mapping is usually implemented by a simple hash function that optimizes for the case of sequential access. Thus most processors use direct-mapped I-caches, where the low-order bits of a memory address are used to...
