Abstract:
An entropy encoder/decoder having a coding mode and a decoding mode, comprising:an input FIFO (first-in first-out) memory to provisionally hold supplied data and output data held therein in their supplied order; an output FIFO memory to provisionally hold supplied data and output data held therein in their supplied order; a bit modeling means for performing a bit modeling operation; an arithmetic coding/decoding means for performing an arithmetic coding operation; the arithmetic coding/decoding means being connected to the bit modeling means; and a control means for controlling operation of the entropy encoder/decoder in said coding mode and said decoding mode; wherein, in the coding mode, the input FIFO memory is connected to the bit modeling means and the output FIFO memory is connected to the arithmetic coding/decoding means; and in the decoding mode, the input FIFO memory is connected to the arithmetic coding/decoding means and the output FIFO memory is connected to the bit modeling means.
