For front to the DCT floating point calculation, it must be more precise than the integer ...

为前向DCT的浮点运算，它要比整数运算更精确。该程序只适用于8×8的块变换。

It uses the memory can be programmed to store in its internal implementation logic operations, the order of operations, timing, counting and arithmetic operations, such as operating instructions, and can be digital or analog input and output, control of various types of machinery or the production process.

它采用可以编制程序的存储器，用来在其内部存储执行逻辑运算、顺序运算、计时、计数和算术运算等操作的指令，并能通过数字式或模拟式的输入和输出，控制各种类型的机械或生产过程。

It have programmable memorizer in which some operation instructions such as logic operation, sequence operation, timing, counting is saved and runs, and then it can control kinds of mechanism and process through input and output of digital or analog signal.

它采用可以编制程序的存储器，用来在其内部存储执行逻辑运算、顺序运算、计时、计数和算术运算等操作指令，并能通过数字式或模拟式的输入输出，控制各种类型的机械或生产过程。

Human brain function similar to the central processing unit installed on the motherboard on the above, it has a superhuman memory and rapid calculation function of precision, it can be scheduled in accordance with the procedures for people to not hesitate to complete the instruction, as well as network traffic as the memory, it can provide more paths and channels to the computer, the faster the computer more efficient, to let the computer voice would also like to assemble a deal with the sound card sound files, as the screen reader software At the same time, prompted the need for sound playback, sound card, therefore the request is relatively high, the best selection of full-featured dual-channel sound card.

类似人脑功能的中央处理器就安装在主板上面，它具有超人的记忆能力和精确快速的运算功能，它能够按照人们预定的程序毫不犹豫地去完成各项指令，还有就象交通路网的内存，它能够提供更多的路径和通道给计算机，使得计算机的运算速度更加快捷，要让计算机能够发出声音还要装配一个处理声音文件的声卡，由于读屏软件所需要同时播放提示声音，因此声卡的要求比较高，最好选用功能齐全的双声道声卡。

Finally, we offer a method to reduce shift communication. In chapter 5, we invent a method based on linear inequalities representation to perform communication optimization and code generation. This method eliminate the restrictions on processable program placed by RSD based method used by RICE Fortran D Compiler or Symbolic Set based method used by PARADIGM Compiler.

第五章提出了一种以线性不等式组作为工具的更加实用化的通讯优化和结点代码生成方法，该方法克服了RICE大学实现FortranD编译器使用的基于规则段描述子的方法以及PARADIGM编译器使用的基于符号集的方法对输入程序的诸多限制，避免了复杂的规则段运算和符号集运算及其造成的无效性，拓宽了可处理的程序类，增强了编译器的处理能力。

Plunder melds and run with this jewel!
