Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The basic idea of ​​the present invention is: according to the picture resolution and / or the limitation of the system memory space, two situations are considered. For small pictures, due to their low resolution, the memory space occupied by converting them into dot matrix arrays is small, so they can be directly stored in the memory in the form of dot matrix arrays; for large pictures, due to their high resolution, converting them into The memory space occupied by the dot matrix array is large, so it can be stored in the file system and read out when it needs to be displayed. In addition, i...

Abstract

The invention discloses a method of picture resource loading in an imbedded system, which comprises: dividing picture resources into small pictures and large pictures according to pictures' resolution or system memory limit; in storing picture resources, storing small pictures data into a memory and storing large picture data into a file system; in loading picture resources, directly loading small picture data from the memory and loading large picture data from the file system. The invention accordingly provides a device for picture resources loading in an imbedded system. The invention realizes picture resources flexible loading and best optimizes picture resources visiting speed and memory cost.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for loading picture resources in an embedded system. Background technique [0002] As we all know, the loading of image resources in an embedded system is a very important part. At present, the system mainly has two ways of loading image resources. [0003] The first image resource loading method: store the image resource in memory. [0004] The basic mechanism of its implementation is to convert the image resource into a global structure, which contains the height and width of the image, the number of bytes occupied by each pixel, and a dot matrix array describing the color value of each pixel of the image, etc. When displaying a picture, take out the dot matrix array directly from the structure and output it to the screen. The advantage of this method is that the access speed is fast and the interface is simple. However, since the picture data is direct...
