Abstract

The invention provides a device and method for reading compact storage image data. The device comprises a reading control unit, a write row cache control unit, a row cache unit, a reading address jumping unit and a configuration information storage unit. The method comprises the steps of: configuring the configuration information storage unit, opening bit configuration of a circuit working switch, reading the address jumping unit, calculating a reading address of each reading action, and sending the reading address to the reading control unit; reading data of a word by the reading control unit, and sending the read data to the write row cache control unit; judging which part of the read data is written in the row cache unit by the write row cache control unit, and according to the judgment result, and writing all or part of the read data into the row cache unit according to the judgment result for the displaying of external images or the use of processing circuits; and circulating in such way until all the rows of the images are completely read. The device and method are used for controlling the reading of a compact image storage mode, and the control process is simple and effective.

Description

【Technical field】 [0001] The invention relates to a reading device and method for compactly storing image data. 【Background technique】 [0002] With the development of image processing technology, the user interface and image special effects of some electronic products are becoming more and more gorgeous, and the corresponding image materials required are also increasing. The characteristics of these image materials are that the images are small and numerous. When processing and displaying special effects, material image data takes up a large amount of storage space, and it will be very meaningful if the storage space of these image data can be reduced as much as possible. [0003] At present, the common storage method is that when the image data width is not an integer multiple of word (computer data unit "word", equal to 32 bits), the invalid part of the last word in a line will be filled with invalid data, and the data in the next line will be filled with invalid data.
