Abstract: An information processing method can comprise updating, in response to an update request for a first item in a file system, first attribute information associated with the first item in an ordered data set comprising entries corresponding to items in the file system, the entries indicating path information of storage paths of the items and attribute information associated with the items, and entries corresponding to items under the same directory being consecutively organized in the ordered data set; determining a second item associated with the first item, a parent directory of the second item being same as that of the first item; acquiring second attribute information associated with the second item from the ordered data set; and determining, based on at least the first attribute information and the second attribute information, attribute information associated with the parent directory. The management efficiency of the file system can thus be improved.

Abstract: A method for processing the Library Exchange Format (LEF) diagram of a layout includes the following steps: Step 1, breaking the LEF diagram into multiple rectangular segments; Step 2, numbering all rectangular segments; and Step 3, combining rectangular segments to obtain a larger rectangular segment and replacing corresponding uncombined rectangular segments with the larger combined rectangular segment. The method reduces the data size of the LEF file and increase the data transmission efficiency of the LEF file.
