Abstract
An arithmetic coding apparatus for carrying out complete pipeline processing is provided. This arithmetic coding apparatus analyzes an input image, reads image information accurately and performs arithmetic coding at ultra-high speed. Using a future prediction type Qe memory removes disturbance in the pipeline caused by renormalization. The arithmetic coding apparatus also generates a common context when coding multi-valued images without distinguishing between an AC component and DC component of a DCT coefficient. The apparatus is also provided with a circuit for outputting an arithmetic code which is a variable-length code with the length fixed to facilitate editing of a reconstructed image.
