    Abstract: PROBLEM TO BE SOLVED: To optimize compressing and extracting operation at hibernation/wake- up time by determining whether or not memory contents are compressed at next hibernation time and later according to the evaluation of the performance of a system. SOLUTION: On a recording device, an area for hibernation is generated in the form of a file, etc., and the contents of an actual memory are compressed and recorded in the generated area (S2). At this time, the size C reduced by the compression is found from the sizes of the contents of the memory before and after compression (S3). At wake-up time, the time X needed to read the contents of some data of size A out of the generated area on the recording device is measured (S6). Further, the time Y needed to read out the contents of memory size B after the compression of the whole memory and extract them on the actual memory is measured (S7). Then it is decided whether Y-BX/ A

    Abstract: PURPOSE: To set software environment which matches the hardware constitution of a data processing system automatically i.e., without operator's intervention even after the hardware constitution changes. CONSTITUTION: This system is provided with a means which previously holds system constitution definition data wherein what software environment should be set is described In the data processing system, makes the system constitution definition data contain the contents of the system constitution, i.e., the description of a condition statement making the contents of software environment different when the data processing system is initialized by referring to the system constitution definition data, and detects the hardware constitution of the data processing system when the data processing system is actuated or reset to process the condition statement according to the detection result.
