Document Type and Number:
WIPO Patent Application WO/2023/030555
Kind Code:
A1
Abstract:
A method and apparatus for determining a data storage bit width, and a method for storing index data. The method comprises: obtaining data to be stored, wherein there are at least four pieces of data, and performing block segmentation on the data according to a preset number, wherein the preset number is equal to 2n, n is an integer greater than or equal to 2, and determining an effective bit number and a maximum effective bit number value corresponding to each piece of data in the block; then equally dividing the number of intra-block data and the like into a first sub-block and a second sub-block, and obtaining the effective bit number contained in the first sub-block and the effective bit number contained in the second sub-block, and performing differential calculation on the effective bit number contained in the first sub-block and the effective bit number contained in the second sub-block to obtain an effective differential value; and finally determining a storage bit width for storing the effective differential value according to a preset storage bit width interval to which the maximum effective bit number value belongs. According to the method provided by embodiments of the present disclosure, the storage bit width occupied by the effective bit number of the data is reduced by storing the differential value of the effective bit number of the data.
