Abstract:
There is described an image compressing/decompressing method and device that provides the lossless data compression/decompression scheme in two separate modules. Partially entropy encoded/decoded data is written to memory by a first module after a first part of the process and retrieved by a second module to perform the second part of the lossless compression/decompression scheme.
