In one embodiment of the invention, the method is applicable in the memory system 100, see also shown in Figure 1, Fig. 1 is the electronic block diagram of memory system 100 in an embodiment for this reason, memory system 100 for example is a Thin Client (thin client) or server computer (server), be based on LINUX operating system 120, have a primary memory 140 and (or claim physical memory, as volatile memory, RAM) and an internal memory 160 (or claim second internal memory, as non-voltile memory, Hard Disk or Flash), primary memory 140 pre-defined capacity are (for example: the ratio of 1: 1 or 2: 1 or the like) and cut apart a former use district 142 and a compression-type spare area 144 are arranged.Former use district 142 is primary memory 140 former positions in order to temporal data.Any SWAP exchange area 145 is not planned as yet in advance in compression-type spare area 144 before start.
Among this embodiment, for example primary memory 140 is 512MB, its use district, Central Plains 142 and compression-type spare area 144 are planned to 256MB respectively in advance, compression-type spare area 144 can be compressed to more than 1/2 preceding (being that ratio of compression is 2) of not compression usually for the compression factor of placing packed data, make former use district 142 (256MB) add that compression-type spare area 144 (256MB*2) can be for the capacity that fully uses 768MB, and be the capacity of 512MB greater than primary memory 140.See also Figure 1 and Figure 2, Fig. 2 is the process flow diagram of server apparatus of the present invention in this embodiment, and the detailed step that memory system 100 carries out in this embodiment is as follows:
Step (201) is when memory system 100 starts, the operating system of LINUX set in advance (be not defined as one) more than one SWAP exchange area 145 (for example RAM DISK) to compression-type spare area 144, when a plurality of default SWAP exchange area 145, whether its capacity is not limit consistent, all for example is 8MB in the present embodiment;
Step (202) is set an internal memory according to the order of former use district 142, compression-type spare area 144 and time internal memory 160 and is used priority, makes the operating system of LINUX use priority to deposit temporal data in accordance with above-mentioned internal memory;
When step (203) was carried out operate as normal when memory system 100, the operating system of LINUX used the former use district 142 of primary memory 140 to carry out the access of temporal data;
Whether not enough step (204) utilizes the operating system of LINUX to monitor the capacity in former use district 142, and judge the capacity store data in former use district 142, if carry out step (205), otherwise return step (203);
Step (205) is utilized the default SWAP exchange area 145 of the operating system monitoring compression-type spare area 144 of LINUX, and judges whether default SWAP exchange area 145 will soon deposit packed data inadequately, if carry out step (207), otherwise carry out step (206);
Step (206) allows the operating system of LINUX deposit temporal data when the capacity in former use district 142 inadequately, but when default SWAP exchange area 145 still enough allows the operating system of LINUX deposit packed data, memory system 100 with inactive temporal data in the former use district 142 after the compression of above-mentioned compression factor, deposit to the default SWAP exchange area 145 of compression-type spare area 144, carry out step (203) so that the access of proceeding temporal data between clearancen with the operating system that LINUX is provided is moved in the former use district 142 of primary memory 140.
Step (207) is deposited temporal data once again inadequately when the capacity in former use district 142, and when packed data will also soon be deposited inadequately in the default SWAP exchange area 145 of compression-type spare area 144, newly-increased another SWAP exchange area 146 is to compression-type spare area 144, operating system for LINUX is placed packed data, return step (203), or step (208) is carried out when also soon allowing memory system 100 deposit packed data inadequately in the newly-increased SWAP exchange area 146 of compression-type spare area 144.Wherein whether the capacity of the SWAP exchange area 146 in the step (207) is not limit consistent with default SWAP exchange area 145.
In addition, stored temporal data arrives a preset 147 (for example default SWAP exchange area 145 is 8MB in default SWAP exchange area 145, then preset 147 can for example be 7.5MB) time, the operating system of LINUX assert that just the default SWAP exchange area 145 of compression-type spare area 144 soon deposits packed data inadequately.
When the capacity integral body of step (208) up to compression-type spare area 144 allows LINUX operating system 120 deposit packed data fully inadequately, LINUX operating system 120 is deposited SWAP swapace 162 to inferior internal memory 160 with inactive temporal data in the former use district 142, so that the former use district 142 of primary memory 140 is moved between clearancen for the access of carrying out temporal data.
So, the present invention has the internal memory temporarily providing room greater than the former capacity of primary memory, and the operating performance that it had also can postpone the opportunity of using time internal memory to exchange as SWAP simultaneously greater than the operating performance of the mode of the SWAP swapace that uses time internal memory.
