您要查找的是不是:
- prefetch microinstruction 预取微指令
- Microinstruction format and the field function. 微指令格式和各字段功能。
- The prefetch queue of the 8088 is 4 bytes, as opposed to the 8086's 6 bytes. 8088 的预取(prefetch) 贮列(queue) 是 4 位元组,相对于 8086 的是 6 位元组。
- However, the Prefetch folder can accumulate too much information over time. Follow these four steps: 然而,预读取文件夹可能累积了太多的信息。
- The time in which one microinstruction is executed. In general, several microcycles are required to execute one instruction. 执行一个微指令所需的时间,通常执行一条指令需要若干个微周期。
- The BLOCK clause will reduce the number of rows included in the next prefetch to the BLOCK value. BLOCK子句会减少对BLOCK值的下一次预读中包含的行数。
- The Microprogrammed Control Unit (MCU) is mainly used to the ordering and obeys of microinstruction. 摘要微程序控制器主要是用于微指令排序和微指令执行。
- As you use your system, Windows XP will rebuild the contents of the Prefetch folder. 当你使用系统时
- This is because the machine will work faster if the execution of the next microinstruction is delayed by one cycle. 这是因为,如果下一个微指令的执行被延迟一个时钟周期,计算机将工作的更快。这个寄存器被称作一个流水线寄存器。
- Find out why you need to clean out the Prefetch folder periodically to keep boot times from dragging. 找出所什么你要定期清空Windows XP预读取文件夹来保持启动时间。
- The time in which one microinstruction is executed.In general,several microcycles are required to execute one instruction. 执行一个微指令所需的时间,通常执行一条指令需要若干个微周期。
- The RAID using Cache smart prefetch algorithm can be applied in more expended data storage environment in case of not reducing the performance. 采用多磁盘Cache智能预取算法的磁盘阵列能够在不降低性能的情况下应用于更广的数据存储环境。
- Performance needs to be considered to set important database parameters such as buffer-pool page size, extentsize, and prefetch size. 此外,还要考虑设置重要的数据库参数,比如缓冲池的页面大小、区段大小和预取大小来调节性能。
- In addition, the SET statement is allowed by Adaptive Server Anywhere for the PREFETCH option, for compatibility, but has no effect. 此外,出于兼容性考虑,Adaptive Server Anywhere允许用SET语句设置PREFETCH选项,但没有效果。
- Prefetchsize determines the number of pages read from disk during a prefetch request and is usually set to a multiple of the extentsize. 预取大小决定在发出预取请求时,从磁盘读取的页面数目,通常将之设置为多个区段大小。
- At last, the approach employs data prefetch strategy to hide I/O latency and then further improves the rendering performance. 在实时绘制时,采用基于视点的细节层次选择策略进行模型的细化;
- Base on the query pattern and the real query parameters, we develope two intelligent prefetch algorithms to fit two kinds of demand in data query. 基于这些模版和参数,提出了两种智能预取算法以适合两类不同的数据查询需求。
- Finally, a preemptive priority model is designed to schedule the prefetch tasks, which mapped the resource access probability to the task priority. 最后,该文还提出抢占式优先级模型来调度预取任务,将资源的访问概率映射为优先级。
- Then on subsequent restarts, Windows XP uses the information in the Prefetch folder to essentially preload parts of those programs at boot time. 这样在以后启动时,Windows XP使用预读取文件夹里的信息来预先装载这些程序中必要的一部分。
- Experiments running on the developed proxy show that if the prefetch process can be executed precisely, the user would never feel any difference while browsing the web mail pages. 实验结果显示如果能够精确执行预先抓取,在浏览网页邮件时使用者将不会感觉到任何延迟。
