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.
Claims19
A variable-length encode/decode processor, comprising:
- a central processing unit;
- an instruction buffer coupled to the central processing unit;
- a getbits processing engine coupled to the central processing unit;
- and
- at least one shared register coupled to the central processing unit and to the getbits processing engine.
