Abstract (en)

[origin: WO8805190A1] A data processing system executes a high level computer language program by encoding statements of the program into variable length tokens and then executing the tokens. Each token is a variable length bit field having a value representative of a semantic element of a program statement and a length representative of the context of the semantic element. A single very large scale integrated circuit (VLSI) processor (40) is microprogrammed to execute the encoded program in a pipeline manner and may be used in conjunction with a host computer (20), such as an IBM PC AT or equivalent system.
