Abstract
A variable-length encode/decode processor includes a central processing unit and an instruction buffer and a getbits processing engine coupled to the central processing unit. Such a processor can be used to encode data as variable-length symbols or to decode variable-length symbols such as those found in an MPEG bitstream.
