An entropy encoder block for use in a context adaptive encoder and an entropy decoder block for use in a context adaptive decoder is presented. The encoder block includes a plurality of encoding elements, for processing encoding search tree look tables corresponding to encoding probabilities used by the context adaptive encoder, at least two of the encoding elements servicing the same probability. In an embodiment, at least one of the encoding search tree lookup tables comprises a set of shared encoding search tree lookup tables, accessible by at least two of the encoding elements. The decoder block includes a plurality of decoding elements, for processing decoding search tree lookup tables corresponding to the decoding probabilities used by the context adaptive decoder, at least two of the decoding elements servicing the same probability. In an embodiment, at least one of the decoding search tree lookup tables comprises a set of shared decoding search tree lookup tables, accessible by at least two of the decoding elements. |
