of waveform features of the encoding. We have presented several prototype systems
including a software-based system using an EISC microprocessor and a custom hardwarebased
system using a Spartan 3 FPGA. Case studies that implement widely used standards
such as ISO 18000 Part 7 and ISO 18000 Part 6C using this automation technique are
presented.
