Disclosed is a bidimensional wavelet conversion integrated circuit structure, belonging to the wavelet conversion field in the grand-scale integrated circuit design technology and the image processing and image compression processing technology, aiming to improve the response speed and the output speed of the whole conversion circuit structure. The conversion integrated circuit structure includes a serial-parallel conversion circuit, a one-dimensional row filter circuit and two one-dimensional column filter circuits; wherein the serial-parallel conversion circuit converts the input image data into parallel data and sends the parallel data to the one-dimensional row filter circuit; the one-dimensional row filter circuit outputs four row filter factors to the two one-dimensional column filter circuits in a unit internal clocking period; the two one-dimensional column filter circuits complete the entire column filter computation and outputs the computation result. Compared with the traditional method, the utility model consumes shorter computation time, uses fewer internal memories and shorter output delay, has the advantages of quick system response and high output speed and is suitable for application occasions such as high-speed computation.
