David Gao is a notable inventor based in Beijing, China. He has made significant contributions to the field of audio technology, particularly in MP3 decoding. With a total of 3 patents to his name, Gao's work has advanced the efficiency and effectiveness of audio decoding processes.

Latest Patents

One of his latest patents is titled "Methods and apparatuses for bit stream decoding in MP3 decoder." This innovative decoding method replaces the traditional buffer used in the decoding process by manipulating the order of data decoding. The method involves reading the head and side information of the current frame and calculating the main data's start address. While decoding the main data, the head and side information of subsequent frames are skipped if the reading of the main data is not yet completed. The start address of the next frame is calculated and accessed directly after finishing the current frame's main data. Additionally, an optimum method for accessing frequency lines utilizes the characteristics of the MP3 frequency line, avoiding the insertion of zeros in the rzero zone by memorizing the initial boundary address.

Another significant patent is the "Method and apparatus for MP3 decoding," which focuses on memory optimization for MP3 decoders. This method employs a pipeline structure to speed up matrix calculations in MP3 decoding. It alters the output sequence of IMDCT calculations so that matrix calculations can be activated before completing the IMDCT calculation. Furthermore, a decoding control method allows for pipeline processing in MP3 decoding, enabling the activation of decoding procedures for subsequent granules while the current granule is still being processed.
