Technologies for performing speculative decompression include a managed node to decode a variable size code at a present position in compressed data with a deterministic decoder and concurrently perform speculative decodes over a range of subsequent positions in the compressed data, determine the position of the next code, determine whether the position of the next code is within the range, and output, in response to a determination that the position of the next code is within the range, a symbol associated with the deterministically decoded code and another symbol associated with a speculatively decoded code at the position of the next code.

An encoder for encoding input data to generate corresponding encoded data is provided. The encoder (10) is operable to process a sequence of elements in the input data from a first element thereof to a last element thereof. The elements have corresponding symbols. The encoder is operable to compute probabilities of symbols present in the sequence, wherein the probabilities of the symbols are computed whilst disregarding those elements of the sequence that have already been encoded into the encoded data. Moreover, the probabilities of the symbols are adaptively changed as the sequence of elements is progressively encoded into the encoded data. Furthermore, information describing the probabilities is delivered; optionally, the probabilities of the symbols are accompanied with additional information indicating how the probabilities are adaptively changing. There is also provided a decoder for performing an inverse of encoding performed by the encoder.

The syntax modeler may associate a first sequence of symbols with syntax elements. The buffer may store tables, each represented by a symbol in the first sequence, and each used to associate a respective symbol in a second sequence of symbols with encoded data. The decoder decodes the data into a bitstream using the second sequence retrieved from a table.
