Abstract
A digital information encoding device used in a QM-Coder comprises a context table storage means for storing a plurality of storing data comprising a prediction symbol and an LSZ data, an arithmetic calculation means for receiving the storing data which is read out according to the address based on a context from a context generation means, and a renewal data generation means comprising a data storage device means, an LSZ renewal logic circuit, and an MPS renewal logic circuit for generating a renewal data based on a storing data and a prediction conversion signal from the arithmetic calculation means. The renewal data is written to the storing data in the context table storage means according to the address based on the context from the context storage means. The digital information encoding device can obtain a high speed processing, which is suitably integrated into a semiconductor integrated circuit.
