1 to 4A and 4B will be described together for convenience of explanation.

The terminal 100 refers to a device for executing a file in cooperation with the cloud storage 200. The terminal 100 includes all mobile and mobile terminals 100 capable of accessing the Internet such as a PC, a mobile phone, a tablet PC, a notebook computer, and a PDA. The cloud storage 200 refers to a service that enables a file to be used on a network basis, and may be expressed as a web hard or the like. The terminal 100 and the cloud may be connected through a wire / wireless network.

The terminal 100 includes a memory 110, a central processing unit 120, and a communication interface 130. The memory 110 records a control program, the central processing unit 120 operates according to the control program, and the communication interface 130 performs communication with the cloud storage 200. The memory 110 includes a cache 112 memory 110 (hereinafter referred to as a cache 112). Cache 112 refers to a memory 110 area that stores a copy of a previously computed piece of results or a file stored elsewhere. The terminal 100 can shorten the time for accessing the actual file by using the file that is cached. If the requested file is found in the cache 112, it is referred to as a cache 112 hit and if the requested file is not found in the cache 112, it is referred to as a cache 112 miss . The size of the cache 112 may be determined by utilization of the memory 110 space.

The cache 112 may be configured differently depending on the attributes (or types) of the files in the cloud storage 200. [ That is, when the file in the cloud storage 200 to be accessed is a multimedia file such as an image, a moving image, a voice, or a document file such as a word / spreadsheet, the cache 112 is configured to be variable according to the free space in the memory 110 . On the other hand, if the file in the cloud storage 200 to be accessed is an application executable file, the cache 112 can be configured as a queue based on a FIFO (First In First Out).

≪ Cache for using a multimedia file &

Referring to FIG. 3, the cache 112 may be variable according to the space in the memory 110. More specifically, the minimum size of the cache 112 may be fixed to a predetermined value. In one embodiment, the minimum size of the cache 112 may be a constant 10 M or a percentage of the total capacity of the memory 110. For example, when the total capacity of the memory 110 is 4G and the predetermined ratio is 1%, the minimum size of the cache 112 may be set to 40M. That is, the minimum size of the cache 112 has a fixed value regardless of the free space in the memory 110.

The maximum size of the cache 112 may vary in proportion to the amount of free space in the memory 110. In one embodiment, if the total capacity of the memory 110 is 4G, the capacity of the memory 110 currently in use is 1G, and the ratio of the maximum size of the cache 112 to the free space is set to 2% The maximum size may be set to 60M, corresponding to 2% of 3G, which is the free space in the current memory 110. [ Thereafter, when the capacity of the memory 110 in use increases to 2G, the maximum size of the cache 112 may be set to 40M which is 2% of 2G, which is the free space in the current memory 110. [ On the contrary, when the capacity of the memory 110 in use decreases to 500M, the maximum size of the cache 112 may be set to 70G which is 2% of 3.5G which is the free space in the current memory 110. [ That is, the maximum size of the cache 112 may increase or decrease depending on the free space in the memory 110. [ With this arrangement, cache 112 utilization can be increased by increasing the size of cache 112 when there is sufficient free space in memory 110.

<Cache to use application executable file>

The cache 112 may be implemented using various types of queues such as a linear queue, a circular queue, a double ended queue, a priority queue, and the like. A queue can be implemented using a contiguous address in memory or using a linked-list. A linked list is a structure that manages data by connecting it with a pointer. A node (Node) used in a linked list may include a data area and a pointer area. FIFO (First In First Out) is also referred to as first-in first-out (FIFO), which means a structure in which the output order is determined according to the input order. That is, when inputting / outputting a plurality of data, the first data inputted first is outputted first. The pointer pointing to the last node immediately before the queue is output is called the front, and the pointer pointing to the first node immediately after the input is called the rear. In a FIFO-based queue, Enqueue means adding a new node to the location pointed to by the rear, Dequeue means returning the information stored in the node pointed to by the pointer, and deleting the node. do. For example, if the pointer is the front, you can return information stored in the frontmost node of the queue (ie, the oldest node that was enqueued) and delete the front node. Also, even if the pointer is one of the nodes inside the queue excluding the front and the rear, the information stored in the node can be returned and the node can be deleted by performing a dequeue. Even when a node belonging to a queue is deleted, information stored in the node can be returned.

In one embodiment, if a file fragment required for application execution is found in the queue, the cache 112 may dequeue the node with the file fragment. Referring to FIG. 4A, the cache 112 decodes the node 404 with the file segment (Available Segment). The node 402 that has pointed to node 404 by resynchronizing node 404 is reset to point to a node (not shown) immediately after node 404. The cache 112 may enqueue the decrypted node 404. Referring to FIG. 4B, the cache 112 has been modified to point to the node 400 as the node to which the rear pointed by enqueuing the decoded node 404 is node 404 and node 404 is pointed to node 400. By performing a dequeue-enqueue operation on the most recently accessed file fragments as described above, the most recently referenced file fragments may be deleted at a later time so that files that are frequently referred to may be stored in the cache 112 for a longer period of time.

5 is a flowchart of a method for executing a multimedia file or document file using a cache.

When receiving an execution command for a multimedia file or a document file in the cloud storage 200 (S100), the terminal 100 searches for a file fragment necessary for executing the file in the cache 112 (S110). For example, the terminal 100 may receive an instruction to reproduce "A. jpg" in the cloud storage 200 and search for a file fragment for "A. jpg "

If a file fragment necessary for file execution exists in the cache 112 as a search result, the terminal 100 executes an execution command using the file fragment (S160).

If there is no file fragment required for file execution in the cache 112, the terminal 100 receives the file from the cloud storage 200, creates a file fragment based on the received file (S120) , It can be determined whether the cache 112 is saturated (S130). For example, if the file fragment for "A.jpg" is not present in the cache 112, the terminal 100 receives "A.jpg" from the cloud storage 200, Can be generated.

As a result of the determination, if the cache 112 is not saturated, the terminal 100 stores the file fragment in the cache (S150) and executes the execution command using the stored file fragment (S160).

As a result of the determination, if the cache 112 is saturated, the terminal 100 expands the maximum size of the cache 112 in proportion to the free space in the memory 110 (S140) and stores the file fragment in the cache 112 (S150), and executes an execution command using the file fragment (S160). For example, if it is determined that the cache 112 is in a saturated state, the terminal 100 may determine that the entire capacity of the memory 110 is 4G, the capacity of the memory 110 currently in use is 1G, If the ratio of the maximum size is 2%, the maximum size of the cache 112 can be changed to 60M, corresponding to 2% of the 3G available space in the current memory 110. The terminal 100 may expand the maximum size of the cache 112 as described above and then store the file fragments in the cache 112 and reproduce "A.jpg" using the file fragments.

As a contradiction to the above embodiment, the terminal 100 may reduce the maximum size of the cache 112 (if it is not shown) if the free space in the memory 110 is reduced.

6 is a flowchart of a method for executing an application executable file using a cache.

When the terminal 100 receives an execution command for a file in the cloud storage 200 (S200), the terminal 100 searches the cache 112 for a file fragment necessary for executing the file (S210). For example, the terminal 100 may receive an instruction to execute "MS-word" in the cloud storage 200 and may search the cache 112 for a file fragment for the "MS- word ".

If the file fragment necessary for executing the file exists in the cache 112 as a result of the search, the terminal 100 performs a dequeue operation on the cache 112 (S260), enqueues the file fragment returned from the queue into the cache (S270) do.

If the file fragment required for file execution does not exist in the cache 112 as a search result, the terminal 100 generates a file fragment based on the file received from the cloud storage 200 (S220) It is determined whether it is saturated (S230). For example, if the file fragment for the "MS-word" is not present in the cache 112, the terminal 100 may send an executable file of "MS- word " from the cloud storage 200 to the cloud storage 200 And generate a file fragment based thereon.

As a result of the determination, if the cache 112 is in a saturated state, the terminal 100 performs a dequeue operation on the cache 112 in operation S240, and encapsulates the generated fragment in the cache 112 in operation S250. For example, when the cache 112 is in a saturated state, the terminal 100 decares the oldest file fragment that has been accessed by deciphering to secure the space of the cache 112, and then executes the execution of the "MS-word " The file fragment created for the user may be enqueued into the cache 112.

As a result of the determination, if the cache 112 is not saturated, the terminal 100 enqueues the generated file fragments in the cache 112 (S250). For example, if the cache 112 is not saturated, the terminal 100 may enqueue the fragment of the file generated for the execution of the "MS-word " into the cache 112. [

The terminal 100 may store the address of the memory in which the file fragment is stored or a pointer indicating the address thereof (not shown), instead of directly storing the file fragment in the newly created node through the enqueue in step S250. .

After the completion of the enqueue, the terminal 100 may execute an execution command using the file fragment that has been incurred (S280). For example, the terminal 100 may execute an execution command using the "MS-word" in the cache 112 after the completion of the enqueue.
