Description of the invention (7) The action of ‘master: S micro: material recovery’ is to restore the data to the corresponding hardware ^ to recall the memory data to the memory of the video memory. #… Σ ， ν " 'Save to the respective register on the chip 处 The processing register and chipset register data back-2 ^ Step as 0' The processing module 103 sets the hibernation flag 104 to the first value, If the value is False, it indicates the dormant state, and as in step ^, the rune device 100 is not in 奘 i π A step S3U, the processing module 103 causes the recovery of the hand-held device 2 to be effective. Then, as in step · 12, the processing module returns to the program counter (PC), and as in step 3, the handheld device 1 is switched back to the user mode. The user can only use the user mode access right. Access is made to the handheld device 100. It is worth noting that the actual situation of storing system information in non-volatile memory in the embodiment of the present invention can be explained by the following two examples. Fig. 4A is a schematic diagram showing a first embodiment of storing system information in non-volatile memory. The example in Figure 4A is a cost-oriented example. The non-volatile memory 410 includes an operating system read-only memory image (OS ROM Image) 411 and a free space 412. In addition, the memory 420 includes an exception table 421, a page table 422, a dynamic stack 423, a storage stack 424, and a free space (free Space) 425 〇 In this example, the data in the memory 420 will be stored in the free space 4 1 2 in the non-volatile memory 4 10. As to whether the data in memory 4 2 0 needs to be compressed or not, it must be regarded as non-volatile memory 4 1 0

The size of the space 412 is larger than that of the memory boat 42, and it can be stored directly without compression. On the other hand, the beehive must be compressed and then stored. Note that if the recorded data is transmitted through Compressed storage, when the data is returned; The corresponding decompression procedure. Ding Lixuan Far Phase = Picture is a schematic diagram showing another example of storing system information to non-volatile memory. Figure 4B Medium, handheld device 100: Doing 3. 4. A Λ J body 4 2 0 non-volatile dedicated non-sleeping of the same size "= storage required when the handheld device just enters hibernation. The module will store the data in the memory 420 directly into the non-volatile memory 43 for exclusive use of hibernation. You can use the data in the memory AM because there is no need to compress the short shore Ϊ Ϊ Similarly, when recovering There is no need to perform the corresponding decompression private sequence, so \ whole The time for entering and leaving the hibernation state will be accelerated. Because the handheld device with hibernation function and the operation method thereof provided by the present invention, the user can trigger the data and system of the handheld device through the hand-held hardware extraction layer The state is stored in the non-volatile memory. 'I Turn off the power, so that the handheld device enters the state, to actually save the power of the handheld device. In addition, the present invention has the following advantages: First, the present invention provides a handheld The device has a sufficiently long standby time, which can prolong the use time of the handheld device. Second, the present invention provides the user with a function of safely storing data in the handheld device, and the user data will not

Description of the invention (9) Because there is no need to purchase an additional third because the power supply is exhausted, this hairpin is based on a button or an expansion card to operate the upper layer, which is better for manufacturers who do not need to hold it. Although the invention is limited by the present invention, the handheld device can be used within the scope and scope. When the scope is subject to the attached conditions, expand the cumming and select an extremely portable device. The data or program is left alone, and the user also waits for the device. Compared with general backup / restore programs, users can only run the computer icon without plugging in or removing any shortcuts. Fourthly, the present invention is implemented in the support of a hardware pumping operation system. For a handheld device, the best embodiment is provided as described above without mentioning the related costs. However, it is not used by the artist. Deviating from the essence of the present invention, changes and retouching, therefore, the scope of protection of the present invention shall prevail.
