摘要： Disclosed is a polytetrafluoroethylene coating agent having low friction and high wear resistance, obtained by dispersing nanodiamond powder in a polar organic solvent, stirring the nanodiamond dispersion solution and a silane coupling agent, and stirring the silane-treated dispersion solution and an oily polytetrafluoroethylene coating solution, in which the silane coupling agent has at least one organic functional group selected from, but not limited to, a mercapto group and an amino group, the organic functional group exhibiting high bondability to polytetrafluoroethylene. A method of preparing the polytetrafluoroethylene coating agent and a method of using the polytetrafluoroethylene coating agent are also provided.

摘要： Provided are a method and apparatus for controlling direct memory access. In the method, data to be transmitted are read and stored in response to a direct memory access controller (DMAC) operation request, and a portion of the data corresponding to an initial burst size is first transmitted to a data destination. After resetting a burst size according to a state of the data destination, another portion of the data corresponding to the reset burst size is second-transmitted to the data destination. If all the data are not transmitted through the first-transmission and the second-transmission, the second-transmission is repeated until all the data are transmitted. If all the data are transmitted through the first-transmission and the second-transmission, an interrupt signal is generated. Therefore, interrupt signals can be less generated, and thus the processor can access an external memory less frequently, thereby increasing system performance.
摘要翻译：提供一种用于控制直接存储器访问的方法和装置。在该方法中，响应于直接存储器访问控制器（DMAC）操作请求来读取和存储要发送的数据，并且首先将与初始突发大小相对应的数据的一部分发送到数据目的地。在根据数据目的地的状态复位突发大小之后，与复位突发大小对应的数据的另一部分被第二次发送到数据目的地。如果所有的数据都不是通过第一次传输和第二次传输传输的，那么重复第二次传输，直到所有的数据被发送。如果通过第一次传输和第二次传输传输所有数据，则产生一个中断信号。因此，可以较少地产生中断信号，因此处理器可以较少地访问外部存储器，从而提高系统性能。
