SRC in SDR is also discussed, and two improved structures of CIC filter are presented. The first one is a CIC decimation filter based on polyphase structure and partially sharpening technique, which is suitable for the situation where the requirements in passband attenuation is not very high while the requirements in alias suppression and operating speed are relatively high. The other one is an improved CIC-Rotated Sinc decimator which possesses improved frequency response, low operating rate and low cost in hardware as well.

The dynamic power_adaptive technique has broken the tradition of the static architecture design in the microprocessor field. It offers a power_adaptive mechanism for key hardware resource on the chip. By analyzing the demand of applications through software, the dynamic power_adaptive technique can offer hint information to hardware, make reconfigurations of the hardware sources according to the change of the demand, and close unnecessary or invalid redundant resources. On the premise of guaranteeing performance, the dynamic power_adaptive technique always serves the present application with the most suitable resource, so as to achieve the goal of saving consumption.

动态低功耗自适应技术打破了微处理器设计中静态体系结构设计的传统，为芯片上关键的硬件资源提供一种动态低功耗自适应机制，通过软件分析应用需求，并向硬件提供指示信息，使得硬件资源根据应用需求的变化动态调整，关闭不必要的或者无效空转的冗余资源，在保证性能的前提下，总是以最合适的资源服务于当前应用，从而达到节省功耗的目的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
