With reference to Fig. 6, in the time of the 100 normal work of described media data playing device, described input-output unit 160 receives the pressing of described power key, and sends the look-at-me that represents shutdown command to described processor 151 (step S100).Described processor 151 is carried out following operation to respond described shutdown command.Described processor 151 is obtained the vector 1534 (step S102) of corresponding described look-at-me in described interrupt vector table 1533, obtains and carry out described vectorial 1534 corresponding routines 1532 (step S104).Under the guidance of described routine 1532, described processor 151 shows pass machine information or stops output video, and reclaiming according to fragment one of them grade of setting the grade to carry out multiple fragments recovery.
Described processor 151 judges that the fragment in described configuration file 1536 reclaims setting 1538 (step S106).When reclaiming, described fragment sets the general fragment recovery of 1538 instruction operation, other program that described processor 151 is correspondingly searched described media data playing device 100 in described internal memory 152 use less than data object (step S107), and discharge the space (step S108) of the shared internal memory of these data objects 152.Described processor 151 records the address 1537 on described internal memory 152, the address (step S110) of carrying out will be continued in described address 1537 for described nucleus module 1535 is designated, and stops power supply to described media data playing device 100 (step S118).
When reclaiming, described fragment sets the high-grade fragment recovery operation of 1538 instructions, described processor 151 stocking system related datas (system context) are to described nonvolatile memory 153, remove described internal memory 152 (step S112), and again drive the movement (step S114) from described nonvolatile memory 153 to described internal memory 152 of described nucleus module 1535 and application program according to the described system related data storing, and reply described system related data (step S115).Remove described internal memory 152 and comprise all data of deleting in described internal memory 152.The movement that responds the described nucleus module 1535 of described shutdown command is called moving for the second time of described nucleus module 1535, comprising load from described nonvolatile memory 153 and the described nucleus module 1535 that decompresses to described internal memory 152.In like manner, the movement of described application program comprise from described nonvolatile memory 153 load and the described application program that decompresses to described internal memory 152.Described system related data comprises the program data structure of nextport hardware component NextPort setting, page table (page table), program management data (process management data), described application program, and other default.Step S115 can only reply the described system related data of part, for example, only reply the described system related data of part to described internal memory 152.Remaining system related data can be replied in the time of device startup 100 next time.Via described step S114 to rearrange data in described internal memory 152 and the arranged distribution of program.Described processor 151 records the address 1537 on described internal memory 152, described address 1537 is to restart the designated address (step S116) that will continue execution of (reboot) rear described nucleus module 1535, and stops power supply to described media data playing device 100 (step S118).For instance, described processor 151 cuts out described power supply unit 158.
The movement of removing described internal memory 152 and described nucleus module 1535 is a part for the routine of the start-up routine of described media data playing device 100.Via execution step S112 and S114, the described start-up routine that described processor 151 was carried out a part before the actual shutdown of described media data playing device 100 is to respond described shutdown command.Described processor 151, before the actual shutdown of described media data playing device 100, and after the movement of carrying out described nucleus module 1535 and application program, can rearrange the situation of utilizing of described internal memory 152.Or in different embodiments, in step S114, described processor 151 can only be carried out the movement of described nucleus module 1535.Described processor 151 is at execution step S107, S108, and S110, S112, S114, S115, and when S116, can first suspend the processing to other look-at-me, described step can not be interrupted.
2.2 device start-up operations
With reference to Fig. 7, in the off-mode of described media data playing device 100, press described power key to send enabled instruction to described processor 151 (step S200).Described processor 151 is carried out following operation to respond described enabled instruction.
In the time receiving described enabled instruction from described input-output unit 160, described processor 151 is carried out load-on module 1531 (step S202).Described load-on module 1531 instructs the initialization (step S204) of described processor 151 and other assembly of described media data playing device 100, and guides described processor 151 to determine whether and has the suitable address (step S206) of continuing and carrying out.When the address 1537 of carrying out when continuing described in judging exists, described processor 151 is obtained described address 1537, and carries out the instruction 1526 (step S208) of the corresponding nucleus module 1535 in described internal memory 152 in described address 1537.Dotted line in Fig. 2 shows the relation between 1537 and instructions 1526 of address.Therefore, the execution of described processor 151 programs switches to the described address 1537 of described internal memory 152.After receiving described enabled instruction, no longer carry out the movement of removing described internal memory 152 and described nucleus module 1535, therefore save described media data playing device 100 and restarted the required time.
When the address 1537 of carrying out when continuing described in judging does not exist, described processor 151 is carried out the general start-up routine (step S210) of described load-on module 1531, load and the described nucleus module 1535 that decompresses to produce described nucleus module 1525 (step S212 and S214), and executive system initialization (step S216) under the guidance of described operating system kernel module 1525.
3. conclusion
In a word, receive shutdown command and actual close described media data playing device 100 during in, the fragment of carrying out multiple grades reclaims one of them grade of operation.Therefore use situation that, can managing internal memory is in order to long use.Subprogram in normal start-up routine, for example movement of operating system kernel module was just carried out the time starting to save before reality starts.
