Infrared image 9/7 wavelet transformation hardware acceleration circuit

Provided is an infrared image 9/7 wavelet transformation hardware acceleration circuit. A data reading control module firstly reads pixel values of an original infrared image from an image RAM according to the preset sequence and starts a wavelet calculation circuit; the wavelet calculation circuit is started to read nine pixel values from the initial q position, and q is made to equal to the sum of q and 2 each time nine pixel values are read; the wavelet calculation circuit is started to read nine pixel values from the q position again till the pixel values are all read according to the current preset sequence; the wavelet calculation circuit reads the first nine pixel values to conduct wavelet transformation so as to obtain a wavelet transformation result; a data writing control module stores the wavelet transformation result into a temporary RAM according to the transposed position; the data reading control module reads pixel values from the temporary RAM according to the same sequence, and the wavelet calculation circuit is started; the data writing control module stores the wavelet transformation result obtained by the wavelet calculation circuit into the image RAM according to the transposed position.
