    • A system for determining an Inverse Discrete Cosine Transformation (IDCT) which utilizes Lee's algorithm. The IDCT system includes initial operating means for receiving discrete cosine transformation data and outputting the result of a first and second addition of the inverse discrete cosine transformation data using Lee's algorithm. Also included are main operation means for receiving the result of the first and second addition of the inverse discrete cosine transformation using Lee's algorithm from the initial operation means and outputting the result of the multiplication operation and butterfly operation of the inverse discrete cosine transformation by using Lee's algorithm.
    • 用于确定利用李氏算法的逆离散余弦变换(IDCT)的系统。 IDCT系统包括用于接收离散余弦变换数据的初始操作装置,并使用李氏算法输出反离散余弦变换数据的第一次和第二次加法的结果。 还包括主要操作装置,用于从初始操作装置接收使用李氏算法的第一次和第二次逆离散余弦变换的结果的结果,并且使用Lee's的方法输出反相离散余弦变换的乘法运算和蝶形运算的结果 算法。

    • Electronic systems using flash memory modules as a main storage, and a booting methods thereof, are provided. The booting method may include reading FAT (file allocation table) information for each of the flash memory modules coupled to the electronic system when it is detected that the number of the flash memory modules coupled to the electronic system has changed, generating SFAT (super-FAT) information including FAT information for each of the flash memory modules, and writing the SFAT information to a boot flash memory module. Thus, device information in the electronic system may be automatically changed when a flash memory module used is inserted or removed.
    • 提供了使用闪存模块作为主要存储器的电子系统及其引导方法。 引导方法可以包括当检测到耦合到电子系统的闪存模块的数量已经改变时,读取耦合到电子系统的每个闪存模块的FAT(文件分配表)信息,生成SFAT FAT)信息,包括每个闪存模块的FAT信息,以及将SFAT信息写入引导闪存模块。 因此,当插入或移除使用的闪存模块时,可以自动改变电子系统中的设备信息。
