Mapping of main memory to a direct mapped cache Example 8.4 Cache Fields To what cache set in Figure 8.5 does the word at address 0x00000014 map? Name another address that maps to the same set. Solution The two

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...
In the above example, each address in the main memory is mapped to one of the four cache lines. To achieve this, we use the modulus operation. So, if there are lines in the cache, direct mapping computes the index using , and the index takes ...
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...
An example of how this value is used is to specify the sector size of a mass storage device. When a bind operation requires a partial mapping, this field is used to ensure that the sum of the sizes of the cookies in a DMA window is a whole multiple of granularity. However, if the ...

While the page table returned by nvidia_p2p_get_pages() is valid for managed memory buffers and provides a mapping of GPU memory at any given moment in time, the GPU device copy of that memory may be incoherent with the writable copy of the page which is not on the GPU. Using the ...
