Digital image compression and decompression
The apparatus comprises a discrete wavelet transform (DWT) engine, a code block manager, and an entropy encoder. The code block manager comprises at least one controller, which losslessly compresses the transform coefficients and stores them in a code block storage for buffering. The entropy coder comprises at least one entropy encoder, each comprising a decoder for decoding the losslessly compressed transformed coefficients prior to entropy encoding.
