Abstract
A method for collecting and processing information bearing indicia (IBI) comprising the steps of: converting light reflected off an IBI into IBI signals representative of the IBI; running at least one signal process for processing the IBI signals on a first processor if the IBI is of a first type; and running at least one signal process for processing the IBI signals on a second processor if the IBI is of a second type, wherein the first processor and second processor are configured to run in parallel.
Claims14
An apparatus for collecting and processing information bearing indicia (IBI) comprising:
- a hand held housing;
- a converter for converting light reflected off an IBI into IBI signals representative of the IBI;
- a first processor configured for running a first signal process for processing the IBI signals if the IBI is of a first type;
- and
- a second processor configured for running a second signal process for processing the IBI signals if the IBI is of a second type,
- wherein the first processor and second processor run the first and second signal processes in parallel and independent of each other, and
- wherein at least a portion of the processing may be achieved via multiprocessing, where different processing threads run simultaneously on the same processor.
