摘要
An encoder-decoder for processing entropy encoded data. The encoder-decoder provides a bitstream buffer for receiving variable length code words that are extracted from fixed length data words received and stored in a register. Variable length words are loaded into the bitstream buffer until all bits are loaded with data, at which time data is read out of the bitstream register and it is cleared and ready for new data. During decoding, the bitstream buffer receives a fixed length data word that is made up of multiple variable length code words. These code words are individually read out and read into a fixed length register. The contents of the fixed length register are then read out for further processing by a connected system. A controller is provided for coordinating and controlling encoding and decoding operation.
