Inverse quantizer
First Claim
1. In a pipeline system having an inverse modeller stage and an inverse discrete cosine transform stage, the improvement comprising:
- a processing stage, positioned between said inverse modeller stage and said inverse discrete cosine transform stage, responsive to tokens for processing data, wherein said tokens each comprise a plurality of data words, each said word including an extension indicator which indicates a presence or an absence of additional words in said token, a length of said token being determined by said extension indicators, whereby the length of said token can be unlimited;
wherein said tokens are communicated from said inverse modeller stage to said processing stage.

Abstract
A multi-standard video decompression apparatus has a plurality of stages interconnected by a two-wire interface arranged as a pipeline processing machine. Control tokens and DATA Tokens pass over the single two-wire interface for carrying both control and data in token format. A token decode circuit is positioned in certain of the stages for recognizing certain of the tokens as control tokens pertinent to that stage and for passing unrecognized control tokens along the pipeline. Reconfiguration processing circuits are positioned in selected stages and are responsive to a recognized control token for reconfiguring such stage to handle an identified DATA Token. A wide variety of unique supporting subsystem circuitry and processing techniques are disclosed for implementing the system.
