    • The firmware update apparatus is configured so that data required for update is accessible from both of normal firmware and emergency firmware and is provided with a section which sets the next-time boot destination to the emergency firmware during update, a section which saves a file before update into an area originally occupied by an update file, a section which inspects that a file required for booting the normal firmware is not broken or confirms that activation is actually possible from a virtualized environment, during activation of the emergency firmware, a section which restores the state before update by the saved files before update and a new update procedure automatically generated by reversing the contents of operations of the update procedure, and a section which, for each update file, describes a necessary reactivation target in the update procedure.

    • The present invention provides a firmware update technique in which a work area is small, a work time is short, update can be resumed even if power-down occurs, and even a file system which does not support writing is supported. To provide the firmware updating technique, an update creating and distributing server divides old and new version firmware images, extracts a difference between the new and old divided firmware images, creates an updated package, and delivers the updated package to an embedded device. On the other hand, the embedded device applies the updated package to the old version divided firmware image (an existing firmware message currently in use).
    • 本发明提供一种固件更新技术,其中工作区域小,工作时间短,即使发生掉电也可以恢复更新,甚至支持不支持写入的文件系统。 为了提供固件更新技术,更新创建和分发服务器分割旧版本和新版本固件映像,提取新的和旧的分割固件映像之间的差异,创建更新的包,并将更新的包传送到嵌入式设备。 另一方面,嵌入式设备将更新的包应用于旧版本的分割固件映像(当前正在使用的现有固件消息)。

    • A device comprises a analysis section for detecting hold errors according to data including the values of the input and output nodes of the FF circuit, and identifying the node in which a hold error has occurred, a determining section for determining insertion of the trailing edge FF or the buffer into hold error sections on the basis of the results of the analysis by the analysis section, a FF insertion section for inserting the FF into a hold error section subjected to position determination so as to insert the trailing edge FF, and connecting a clock line to the FF based on the results of the determining section, and a buffer insertion section for inserting the buffer into the hold error section subjected to the position determination so as to insert the FF based on the results of data of the determining section.
    • 一种设备包括:分析部分,用于根据包括FF电路的输入和输出节点的值的数据检测保持错误,以及识别发生保持错误的节点;确定部分,用于确定后沿FF的插入 或缓冲器保持误差部分,基于分析部分的分析结果,FF插入部分,用于将FF插入到经过位置确定的保持误差部分中,以插入后缘FF,并将 基于确定部分的结果的FF的时钟线,以及缓冲器插入部分,用于将缓冲器插入到经过位置确定的保持错误部分中,以便基于确定部分的数据的结果来插入FF。
