快速缓冲贮存内存(Cache Memory) 快速缓冲贮存区是一个位置非常接近中央处理器的较小容量的高速内存。快速缓冲贮存区是为了向中央处理器供应最常被要求的指令以及资料所设,由於从快速缓冲贮存区取得资料所需时间只是从主内存取得资料所需时间的数分之一,快速缓冲贮存区的设置能够节省许多时间。如果所需要的资讯并不在快...

Memory caching works by first setting aside a portion of RAM to be used as the cache. As an application tries to read data, typically from a data storage system like a database, it checks to see if the desired record already exists in the cache. If it does, the application will read ...
Cache memory works as a link between the processor and main memory and allows the processor to access data faster than it would if it had to go through the main memory every time. Cache stores copies of frequently used instructions and data from main memory into its own faster ...

Types of Computer Memory System RAM Cache and Registers Computer Memory Basics Although memory is technically any form of electronic storage, it is used most often to identify fast, temporary forms of storage. If your computer's CPU had to constantly access the hard drive to retrieve every...
首先需要注意的是在GPU中,将HBM,High Bandwidth Memory视为Main Memory,也就是我们熟知的显存(对应着CPU中的DDR内存)。并且在GPU中,Register寄存器被视为了caches的一部分!即GPU在每个thread线程中使用了大量的Register(甚至比L1级cache的数量还要多)作为离计算单元最近的cache,来保证计算时较低的Latency。
在 task graph 里面,每个图片的解码都有自己独立的解码任务。 软件光栅化与 gpu 光栅化使用不同的解码缓存。 SoftwareImageDecodeCache 管理解码,缩放和颜色校正,而 GpuImageDecodeCache 进一步需要将解码后的位图上传到 gpu 进程生成纹理,使用 gpu discardable memory 来缓存纹理。
If a resource is considered stale, the origin server gets asked to validate it to determine whether the data in the cache still matches what's on the origin server. If the file has been modified on the origin server, the cache updates its version of the resource. Otherwise, if the ...
