    • A method of updating computer software includes identifying an orphaned computer file in a second version of computer software, the orphaned computer file having a name that does not correspond to any name of a computer file in a first version of computer software and computing symmetric divergence between the orphaned computer file and each computer file in the first version of computer software. The method also includes choosing a file from the computer files in the first version of computer software that yields a minimum value of symmetric divergence between the file and the orphaned computer file and using the file as a reference file for compressing the orphaned computer file.
    • 更新计算机软件的方法包括在计算机软件的第二版本中识别孤立的计算机文件,所述孤立的计算机文件具有与计算机软件的第一版本中的计算机文件的任何名称不对应的名称,并且计算在第 孤立的计算机文件和计算机软件的第一个版本中的每个计算机文件。 该方法还包括从计算机软件的第一版本中的计算机文件中选择一个文件,该文件产生文件和孤立计算机文件之间的对称分歧的最小值,并使用该文件作为压缩孤立计算机文件的参考文件。

    • Disclosed herein is an electronic device capable of providing efficient fault-tolerance update processes by employing a backup memory block used in conjunction with a block-by-block update process, wherein the backup memory block may be employed to store backup content computed using updated contents of a first memory block and contents of unmodified second memory block. The first and second memory blocks may be recoverable following a fault by computations using the content of the backup memory block. Fault-tolerant recovery processes according to an embodiment of the present invention apply the contents of the backup memory block to efficiently recover from faults occurring during update of one of firmware and software in an electronic device.
    • 本文公开了一种电子设备,其能够通过采用结合逐块更新过程使用的备份存储器块来提供有效的容错更新过程,其中备用存储器块可用于存储使用更新的内容计算的备份内容 的第一存储器块和未修改的第二存储器块的内容。 通过使用备份存储器块的内容进行的计算,第一和第二存储器块可以在故障之后恢复。 根据本发明的实施例的容错恢复过程应用备份存储器块的内容以有效地从在电子设备中的固件和软件之一更新期间发生的故障中恢复。
