Abstract:
1. A method for decompressing a data stream with a decompression device comprising at least a first module and a second module, the method comprising: receiving a compressed bit stream in the first module; applying a first set of lossless decoding schemes to the compressed bit stream in the first module to produce a first set of reconstruction parameters and transform coefficients, wherein the first set of lossless decoding schemes comprises arithmetic decoding; writing to memory the first set of reconstruction parameters and transform coefficients and a remaining portion of the compressed bit stream; retrieving from memory the first set of reconstruction parameters and transform coefficients and the remaining portion of the compressed bit stream by the second module; applying a second set of lossless decoding schemes to the bit stream to recover a second set of reconstruction parameters and transform coefficients in the second module; and processing the data stream using a lossy decompression scheme to recover the data stream as decompressed.
