36 RFID Handbook: Applications, Technology, Security, and Privacy
consists of automatically generated controller and physical layer hardware that works with
existing air interface blocks. To generate the controller and physical layer blocks, a design
automation methodology has been developed.
For the physical layer, the methodology allows the speci?¬?cation of waveform features of
the encoding, which are speci?¬?ed in a textual format. These features are then used as inputs
to parameterized hardware blocks and combined with automatically generated customized
hardware blocks. The result is automatically generated encoding and decoding
hardware blocks.
For the controller, the methodology allows RFID primitives or the commands employed
by the RFID system to be speci?¬?ed using RFID macros, an assembly-like format. These
RFID macros are processed to generate a template ?¬?le to specify the behavior for each
primitive or macro. All behavior is speci?¬?ed using ANSI-C allowing the user to create
arbitrarily complex behaviors. Finally, the RFID compiler generates the ?¬?nal controller
used for managing the tag. This technique allows the seamless coexistence of several RFID
standards such as the American National Standards Institute (ANSI) standard 256??“2001 [1]
and the International Standards Organization (ISO) standard 18000 Part 7 [2].
