Its character is that the DDFS is linked to a microcomputer bus through buffer driver to control frequency and phase. The necessary hardware and software are designed.
实际上,缓冲可能发生在其它不同的级别,例如硬盘本身、控制器或内核磁盘驱动设备驱动程序,所以我们的工作可能对性能影响不大。
In practice, buffering may occur at various other levels, such as on the hard disk itself, the controller, or the kernel disk drive device driver, so ours may not make much of a difference.
一旦调用aio_complete(),驱动程序就不再拥有IOCB或者用户缓冲区了,不应该再触碰它们。
Once you have called aio_complete(), you no longer own the IOCB or the user buffer, and should not touch them again.

否则,数据会通过驱动器缓冲被分段。
帧缓冲区驱动程序通常有三层。
缓冲区缓存之下是设备驱动程序,它实现了特定物理设备的接口。
Below the buffer cache are the device drivers, which implement the interface for the particular physical device.
缓冲区的格式、顺序和内容仅对前端和后端驱动程序有意义。
The format, order, and contents of the buffers are meaningful only to the front-end and back-end drivers.
缓冲池应该大到足以在内存中保留所需的数据,以便减少硬盘驱动器的活动。
The buffer pool should be large enough to keep the required data in memory so that hard disk drive activity can be reduced.
当从硬盘驱动器读写表和索引数据时,DB 2使用缓冲池来缓存它们。
DB2 USES buffer pools to cache the table and index data as they are being read or written to the hard disk drive.
加载驱动程序将使用连接器中的数据并构建 64k缓冲以便发送给Teradata数据库。
The load driver will use the data from the connector and build 64k buffer to be sent to the Teradata database.
不会有老式驱动器那样的缓冲区欠载运行烦恼。
swtrace等PerformanceInspector工具与驱动程序相互协作以利用存储在固定缓冲区中的信息。
The Performance Inspector tools, such as swtrace, interact with the driver to make use of the information stored in the pinned buffers.
内核追踪挂钩调用设备驱动程序代码中的函数,那些函数将内核追踪挂钩在固定缓冲区(pinned buffer)中给出的信息记录下来。
The kernel trace hooks call functions in the device driver code, which log the information provided by the kernel trace hooks in pinned buffers.
正如上面所说的,应用程序通过Winsock来和传输协议驱动程序交谈,而AFD . SYS负责为应用程序进行缓冲区管理。
As just mentioned, AFD.SYS handles buffer management for applications that use Winsock to talk to the transport protocol drivers.
日志缓冲区将容纳存储器中的日志记录,直到它们被写回硬盘驱动器。
The log buffer holds log records in storage until they are written to hard disk drive. Log records are written to the hard disk drive when one of the following occurs.
注意,可以使用sync命令将缓冲区缓存中的请求发送到存储媒体(迫使所有未写的数据发送到设备驱动程序,进而发送到存储设备)。
Note that you can use the sync command to flush the buffer cache out to the storage media (force all unwritten data out to the device drivers and, subsequently, to the storage device).
其它特性包括:集成缓冲用来驱动基准电压,以及集成完全差动放大器用来缓冲调制器输入并进行电平转换。
Other features include an integrated buffer to drive the reference as well as a fully differential amplifier to buffer and level shift the input to the modulator.
如果你用长电缆,或驱动(例如并行DAC)几个数模转换器,对于缓冲区中的数据信号它是很好的做法。
If you are driving long cables, or are driving several DACs (parallel DAC for example), it is good practice to buffer the data signal.
在数据流的路径上添加了相应的驱动和缓冲模块,避免了冲突,保证了数据的完整性。
The corresponding driver module and buffer module are appended in the route of data flow to avoid data conflict and ensure data integrality.
