Embodiment Construction

[0020] The present invention is characterized in that the storage object is determined dynamically and has serial characteristics, that is, when the storage object arrives, the size of its data structure cannot be determined, and the size of the data structure has a variation range of 64bytes to 32Kbytes. In the real-time communication of the terminal using the method of the present invention, the data received each time needs to be added to the previously allocated data structure, and the separate storage mode is used in the allocation of the data structure to achieve the purpose of optimizing the storage structure.

[0021] The method of the present invention does not focus on memory management, but performs format changes in processing dynamically growing data structures, so that the phenomenon of low memory utilization rate is improved. For example, in the chip communication, a frame of indefinite length before reception arrives. At this time, if according to the original i...

Abstract

The invention provides a method for storing the data stream of volatile frame size structure. Its characters are as follow: it includes a process to dynamic allocate the data frame size structure for the received described data stream of volatile frame size structure. In this way, it can formulate a specific data structure model to improve storage space utilization and further improve the mobile phone products such as chips embedded computing capacity through the utilization of particular modules and the use of the data structure characteristics.

Description

technical field [0001] The invention relates to an embedded system, in particular to a method for storing data streams with an indeterminate frame length structure suitable for embedded products with large storage limitations such as mobile terminals. Background technique [0002] Embedded products have large storage limitations and have always been the weak link of mobile phones. At present, the data storage part of a specific frame structure uses a continuous space storage mode, and the space allocation of the mobile terminal is fixed, and the size of the storage space is specified by the user during allocation. FIG. 1 shows the frame structure of the continuous storage mode adopted by embedded products in the prior art, which is expressed by a continuous space structure and has a fixed length. The maximum length of the frame structure determines the size of the storage space. For a case where the frame length is small, the storage space will be wasted to a certain extent...
