Method and system for sharing document

Abstract

This invention relates to file common method and system applied in multiple program electron device, wherein, the file system comprises the following parts: integration module to integrate electron device needed files and to store special memory unit; mapping module to record and store unit each file relative body memory address and establishing relative mapping list; process module to find relative body memory address according to application program to take program to execute relative operation relative files.

Description

technical field [0001] The invention relates to a data processing technology, in particular to a method and system for providing application programs to directly read documents in a shared manner. Background technique [0002] The storage unit is a very important part of computer hardware. It stores system programs and data information to ensure the normal operation of the computer system. There are many types of storage units. If they are classified according to their usage, they can be divided into main storage unit (referred to as internal memory) and auxiliary storage unit (referred to as external storage). [0003] External storage is usually a magnetic medium or an optical read-write medium, such as hard disk, floppy disk, CD, etc., which can store information for a long time and is not affected by power supply. However, external storage devices are generally driven by mechanical components, so their access speed and A computer processing unit (hereinafter referred to...

Problems solved by technology

[0008] As mentioned above, the disadvantages of the existing file sharing technology are: (1) Since the access speed of the hard disk is much different from that of the CPU, the files stored in the hard disk must be loaded into the memory to provide the CPU with the read operation. , thus slowing down the reading speed of the document

(2) When the CPU executes the application program "APP1" 111, it randomly loads the document into a suitable physical address in the memory, so that when the CPU executes the application program "APP2" 112, it cannot know the application program The document 12 accessed by "APP1" 111 is stored in which physical address in the internal memory 14, so the document 12 must be loaded into the internal memory 14 again, that is, a total of 9K (3K hard disk space + 6K internal memory) is required space) storage space is used to store the document, wasting a lot of storage space

[0010] Currently, handheld devices on the market have limited memory capacity due to size and cost considerations. Therefore, how to provide a new file sharing technology to solve the lack of storage space waste in the existing technology has become an urgent problem to be solved.
