DATA PIPELINE DEVICE AND DATA ENCODING METHOD

摘要

PURPOSE: To prevent the operation delay of a certain processing stage from stopping all pipeline operations in a pipeline processing structure of a multistage constitution. CONSTITUTION: A pipeline structure processes data at continuous stages. The stages which are adjacent to each other are connected together via the valid lines (IN-VALID, OUT-VALID) and acceptance lines (IN-ACCEPT, OUT- ACCEPT). The transfer of input data are performed all at once among all stages that satisfy the conditions in every cycle period of a clock signal and only when the signals received from the following stages are affirmative. A decoding circuit is provided on one of processing stages, and the data included in a block are processed at the processing stage when one or more prescribed bit patterns are decoded at the beginning of the block.
