Abstract
A method and apparatus for optimizing the data throughput of decoded-output scanners by maintaining a tracking relationship between the scanning and decoding operations thereof. Data is scanned from an indicia to be read on an uninterrupted cyclic basis and stored in memory. Also stored is continuously updated data that allows the most recently completed block of scan data to be identified. Data is decoded on an uninterrupted cyclic basis, at the same timet hat new data is being scanned. A loose, tracking relationship is maintained betwen the scanning and decoding operations so that decoding always begins with the then most currently available data.
