Latest Patents

One of Hailiang Li's latest patents is titled "Hardware implementation of frequency table generation for Asymmetric-Numeral-System-based data compression." This invention introduces a lossless data compressor that prevents normalization overruns on-the-fly. It achieves this by rounding symbol occurrence counts to generate symbol frequencies, allowing an encoding table generator to create entries without waiting for the symbol frequency table to complete. The design compensates for rounding errors by adjusting symbol frequencies when certain conditions are met, thus reducing latency in encoding table generation.

Another notable patent is "Predicting compression ratio of data with compressible decision." This invention features a data-compression analyzer that can quickly decide whether to compress an input data block. It utilizes a Concentration Value (CV) and a Number of Zero (NZ) symbols to make rapid decisions based on a calculated threshold. The method includes training a regression model to optimize the decision-making process, enhancing the overall efficiency of data compression.
