Embodiment approach

[0074] 1) If the first index is grouped into the above-mentioned case 1), a storage area can be divided in the internal memory, the storage area is used as the first storage area, and the multiple first features are continuously stored in the first storage area.

[0075] For example, the multiple first features are respectively the first feature f1 to the first feature fn, and n is the number of the multiple first features. It is assumed that the storage space occupied by a first feature in the internal memory is the storage corresponding to a storage address. Space, the first feature f1 to the first feature fn can be continuously stored in the first storage area as Figure 7A As shown, the storage address 1 of the first feature f1 is continuous with the storage address 2 of the first feature f2, the storage address 2 of the first feature f2 is continuous with the storage address 3 of the second feature f3,..., the storage address of the first feature fn-1 The storage address n-1...

Abstract

The invention discloses a method for establishing an index and a related device. The method comprises: determining a plurality of first features to be stored in an internal memory, with the pluralityof first features belonging to a first index group, the first features being used for feature calculation by an arithmetic processor, the first features being features obtained by feature extraction and / or processing of multimedia data; storing the plurality of first features in the internal memory, the plurality of first features being continuously stored in a first storage area of the internal memory; establishing address index information of the first storage area, wherein the address index information is used for indicating an address of the first storage area in the internal memory; and reading the first feature to the arithmetic processor according to the address index information. According to the technical scheme, the speed of reading the features to the arithmetic processor can beincreased, and therefore the utilization rate of the arithmetic processor is increased.

Description

Technical field [0001] This application relates to the field of computer technology, and in particular to methods and related devices for indexing. Background technique [0002] Features are data used to describe the content attributes of one or more aspects of multimedia data. In the scenario of using features for feature calculation, due to the different data formats, fields, field types, field lengths, etc. used by different feature calculation algorithms, it is necessary to index the features so that when performing feature calculations based on these algorithms, you can Call the algorithm-related features based on the index. Feature calculation can be specifically applied to data retrieval scenarios, data mining scenarios, and so on. [0003] The feature calculation is completed by the arithmetic processor of the computer. Due to the limited storage space of the arithmetic processor, the feature is generally stored in the internal memory of the computer. When the arithmetic...
