Abstract:
1. An image coding apparatus for frequency-transforming a block constituting an image and generating a code stream based on an obtained transform coefficient, comprising: a plurality of codes generation units arranged in parallel, which are configured to generate codes, including one or more codes, based on the transform coefficient; a plurality of first code concatenation units arranged in parallel, each of which is configured to concatenate each code, constituting the codes generated by said codes generation units, for generating a partial code stream; a plurality of storage units arranged in parallel, each of which is configured to store the partial code stream inputted from said first code concatenation unit; and a second code concatenation unit configured to read the partial code stream, which is stored in each of said plurality of storage units, and concatenate read partial code streams for generating the code stream for output, wherein each of said storage units is configured with at least two memories for simultaneously outputting a last of partial code streams which is stored in one of said memories and a first of partial code streams which is to be concatenated next and stored in another of said memories.
