Simply put , directx is a windows technology that enables higher performance in graphics , including full - color graphics , video , and 3 - d animation , and sound , including surround sound , when you are playing games or watching video on your pc 简单地说， directx是一项windows技术，在pc上玩游戏或观看视频时，可以实现更高性能的图形（包括全彩色图形） 、视频和3 - d动画以及声音（包括环场声音） 。
Experiments show that , when use msp430f149 audio sensor to identify vehicles that contain plane , tank , truck and so on by time domain features and two - level f - ratio , the recognition rate is 82 . 1 % ; when use both msp430f149 audio sensor and arm9 sensor to identify vehicles , and the recognition rate is much better than the original system and msp430f149 audio sensor . line spectrum of power spectra and 3 / 2 spectrum is used as frequency features on arm9 sensor , and it is caught by narrow - band bandpass filter 实验证明,在主频为8mhz的msp430f149感知器上,采用基于时域特征和二阶f比的识别算法,能够实时地完成对飞机、坦克、卡车等交通工具的识别;将msp430f149感知器与基于arm9的高端感知器配合使用,且高端感知器采用功率谱线谱或3 / 2维谱线谱作为频域识别特征,能够实时的对各类交通工具做更高性能的识别。
In detail , the embedded pc technology will be used in the system using in temperature control system , design hardware and software to the appointed control equipment , which make for setting up the excellent property control system of intelligent appearance ; the object controlled will be set up mathematical modeling and analyzed temperature field , which is in favor of the optimizing design of temperature control system ; the research of control arithmetic is based on the object controlled behavior analysis . the paper will analyze the control arithmetic mostly used in temperature control and use modified fuzzy control method based on rules into temperature control system , and gets relatively perfectly control effects . so it prove tha t it is feasible that using fuzzy control method realizes temperature control system 系统采用了现在用在温控系统中还很少的嵌入式pc技术，并结合具体的控制装置进行了硬件和软件设计，这有利于构建更高性能的智能仪表化控制系统；对被控对象进行了数学建模及温度场的分析，这为温控系统的优化设计提供了帮助；在对被控对象特性分析的基础上进行了控制算法的研究，将基于规则修改的模糊控制方法用于温度控制系统，得到了比较好的控制效果，由此，在温度快速变化的系统中采用模糊控制技术是一个比较好的选择。
We implement the mpcls which make use of the shared memory to communicate . ( 2 ) stsf scalable task scheduling frame : scalable task scheduling mechanism makes up the faulty of rtems which only use one scheduling algorithm - rm algorithm . and an improved rm algorithm which uses double - pri strategy is implemented ( 2 )可扩展的任务调度框架- - stsf ( scalabletaskscheduleframe ) :本文设计的可扩展的多处理器任务调度框架弥补了rtems只采用一种调度算法- - rm调度算法带来的局限性,并实现了更高性能的基于双优先级策略的rm调度算法。
