    • A delay locked loop (DLL) circuit includes a clock input buffer that generates a reference clock signal by buffering an external clock signal and outputs the reference clock signal by correcting a duty cycle of the reference clock signal in response to a duty cycle control signal. The DLL circuit also includes a timing compensation unit configured that generates a compensation reference clock signal by compensating for a toggle timing of the reference clock signal that is changed during the duty cycle correction operation in response to a timing control signal. The DLL circuit further includes and a duty cycle control unit that generates the duty cycle control signal and the timing control signal by detecting the duty cycle of the reference clock signal.
    • 延迟锁定环(DLL)电路包括时钟输入缓冲器,其通过缓冲外部时钟信号产生参考时钟信号,并通过响应于占空比控制信号校正参考时钟信号的占空比来输出参考时钟信号。 该DLL电路还包括定时补偿单元,该定时补偿单元被配置为通过补偿在占空比校正操作期间响应于定时控制信号而改变的参考时钟信号的触发定时来产生补偿参考时钟信号。 该DLL电路还包括一个占空比控制单元,其通过检测基准时钟信号的占空比来产生占空比控制信号和定时控制信号。

    • The present invention discloses a device and method for detecting a packed PE (portable executable) file. In the device and method for detecting a packed PE file, information for detecting packing are extracted by analyzing the header of a target file, and a record containing characteristic values shown only in a packed PE file is created by using the extracted information. The packing of the target file is detected by calculating the similarity with a PE file which is not packed based on the created record and comparing it with a derived threshold value. Therefore, a packed PE file can be detected even if it is packed by a packing method which is not well-known.
    • 本发明公开了一种用于检测打包PE(便携式可执行文件)文件的装置和方法。 在用于检测打包的PE文件的装置和方法中,通过分析目标文件的标题来提取用于检测打包的信息,并且通过使用所提取的信息来创建仅包含在打包的PE文件中的仅包含特征值的记录。 通过计算与基于创建的记录不打包的PE文件的相似度并将其与导出的阈值进行比较来检测目标文件的打包。 因此,即使打包的PE文件由不是众所周知的打包方法打包也可以被检测。
