In volatile memory；Whether be stored with the snapshot block of loaded in the default volatile memory of real-time judge；If so,
Whether the snapshot block for then judging loaded is the snapshot block compressed；If so, the snapshot block then compressed in real time to this enters
Row decompression.The loading and the decompression of another snapshot block of a snapshot block can be carried out simultaneously, for example, n+1 as shown in Figure 2
Individual snapshot block is the snapshot block compressed, and BLOCK#0 is loaded onto in volatile memory, in follow-up cyclic process,
BLOCK#0 is decompressed while BLOCK#1 is loaded, and follow-up snapshot block located in a parallel fashion according to this
Reason.Certainly, in the present embodiment, it can come to be compressed part or all of snapshot block as needed, if loading is current
Snapshot block is simultaneously uncompressed, and is directly loaded.
It should be noted that the so-called load time refers to snapshot block by nonvolatile memory to volatile memory
Time.The deadline of each snapshot block refers to that correspondence snapshot block needs the time loaded completely, in present embodiment
In, snapshot block need loaded completely within itself corresponding deadline so that terminal device from off-mode run to
Normal operation condition.The compression ratio of each snapshot block indicates the degree for the amount of capacity that each snapshot block needs are cut in.

If volatile memory in, including：Judge whether each snapshot block being stored in default nonvolatile memory includes system
Restart necessary data；If so, then the snapshot block is loaded onto in default volatile memory.
In the present embodiment, the data page for needing to load when system starts whether can be contained according to recent snapshot block
Determine whether recent snapshot block is a necessary snapshot block etc. information.If needing to add when recent snapshot block does not start comprising system
The information such as the data page of load, then recent snapshot block is exactly an inessential snapshot block, then even without being loaded onto volatile storage
In device, the quantity of the snapshot block of loading can be so reduced, so as to reduce the load time.
Such as block#0 is a necessary snapshot block, compare block#0 the decompression time and block#n loading when
Between, that is, last block load time, if block#0 decompression the time be less than block#n load time, enter
One step decides whether block#0 being compressed higher than speed set in advance with one, however, it is determined that block#0 is high with one
It is compressed in speed set in advance, then decision-making is finished, block#0 can be compressed.
The loading and decompression of snapshot block may be carried out synchronously.For example, block#0 is loaded in time t, block#1 exists
Time, (t+1) was loaded, if block#0 is a compression snapshot block, block#1 loading and block#0 decompression
It may carry out simultaneously；For another example if block#1 is not compression snapshot block, block#1 decompression may not be run；Phase
With, if block#1 is a compression snapshot block, block#2 loading and block#1 decompression may be in time (t+
2) carry out simultaneously.
It should be noted that this synchronization process mode needs terminal to configure multiple processors.If for example, terminal is configured
Two processors and two processor independent operatings, then a processor can be configured to handle the loading of snapshot block, separately
One processor is arranged to handle the decompression of snapshot block.
