A symbol processing system incorporated in an NMOS/LSI chip separates valid data from invalid data all generated by scanning a bar-coded symbol. The signals representing the bars and spaces of the symbol are decoded by a pattern recognition array, and the decoded data is clocked into a storage unit. When valid data is discovered, such data is captured within the storage unit. The valid data is then clocked out of the storage unit to a utilization device for further processing. |
