ABSTRACT:
A multi-port digital signal decoder capable of decoding digital signals produced from various types of scanning devices including, for example, high-speed counter top scanners, low-speed hand-held scanners, wand scanners, light pen scanners, and magnetic card scanners. The digital signal decoder of the present invention includes a plurality of data input ports for receiving digital input signals produced from the various scanning devices. The digital signal decoder also includes common digital signal and data processing circuitry for processing the digital input signals and digital data so as to produce, as output, decoded symbol data. In addition, the digital signal decoder further includes an output data port for providing the decoded symbol data to a host device operably connected to the digital signal decoder. In the illustrative embodiment, the digital signal decoder is realized using VLSI circuit and microprocessor technology.
