Memory is the best persistent store for a cache because access time is ( practically) instantaneous and RAM is typically plentiful ( or cheap to amass). 内存是缓存的最佳持久性存储,因为访问时间(实际上)是即时的并且RAM的容量通常都很大(或者容易聚集在一起)。
We've also presented and explained how to use several powerful new features, such as revalidation in memory and access to type information& something developers have been asking for for a long time. 我们还展示并解释了如何使用几个强大的新特性,例如内存中的重新验证以及对类型信息的访问&这些都是开发人员长期以来梦寐以求的特性。
Generally, the memory hierarchy follows the access time with the fast CPUregisters at the top and the slow hard drive at the bottom. 一般来说,内存层次结构如下的访问时间与快速的CPU寄存器顶部和缓慢的硬盘驱动器在底部。
A portion of memory having short access time, as compared to the main memory of the central processing unit. 与中央处理机的主存储器相比具有更短存取时间的存取时间的存储器。
Data Prefetching Technique of Nonlinear Memory Access Effective prefetching can reduce average response time of read operation and improve the throughput of RAID. 在RAID(廉价冗余磁盘阵列)系统中采用有效的预取技术可以缩短主机读请求的平均响应时间,提高磁盘阵列的数据吞吐率。
Used the idea of the double buffer and direct memory access, a real time data acquisition and logging about the succession, big capacitance leakage current is realized; A digital filter is designed to filter high frequency signals. 运用双缓冲和内存直接映射的设计方法实现对连续、大容量泄漏电流信号的实时采集和存储;
The use of cache reduces memory access time and load. 使用Cache有两点好处:减少访存链时间及减轻访存负载。
Via the technology, optical memory can overcome some limits and reach higher density and shorter access time. 通过此技术,光盘存储可以突破原有局限,实现更高的存储密度和更快的存取速度。
Memory access, run control and real time trace are three approaches of debugging. 调试的方法主要是目标访问、运行控制以及实时跟踪。
Because memory access time is far less than disk access time, gaining direct access to data from memory database will save much time in processing transactions. 由于内存访问时间远远低于磁盘访问时间,在对事务进行处理时,若能直接从内存中取到所需数据将会节省很多时间。
The program could hide memory access latency well when it has high compute density ( the ratio of computing time to memory access time). 当对于并行数据集有较高的计算密度(即计算时间和访存时间的比率)时,能够很好的隐藏存储器的访问延迟,不需要很大的数据缓存。
