Abstract
A method and apparatus for processing data. According to a preferred embodiment, the apparatus comprises a plurality of datapaths, each datapath comprising datapath processor, and a statistical decoder input channel device. The statistical decoder input channel device prefetches variable length encoded data from a variable length encoded data source in response to a request by a program running on a datapath processor of a datapath of the plurality of datapaths. The statistical decoder input channel device comprises a statistical decoder processor and memory for decoding the variable length encoded data to provide fixed length decoded data, and a transmission output channel for transmitting the fixed length decoded data to the datapath.
