Abstract
Abstract A system for scanning bar code labels and for providing data related thereto includes scanning means for optically scanning bar code labels and providing an electrical, binary scan signal in response thereto. The scanning means includes a scanner and a scanner controller, and an integrated circuit. The integrated circuit includes a converter means, responsive to the scanning means, for translating the electrical, binary scan signal into a related sequence of digital words. The integrated circuit further includes a microprocessor means, responsive to the converter means, for translating the related sequence of digital words into data. The microprocessor means has first and second microprocessor circuits for independently translating the sequence of digital words into data. The microprocessor means also has a random access memory for storing the appropriate software to control operation of the first and second microprocessor circuits.
