A Field Programmable RFID Tag and Associated Design Flow

Current Radio Frequency Identification (RFID) systems generally have long design times and low tolerance to changes in specification. This paper describes a field programmable, low-power active RFID tag, and its associated specification and automated design flow. RFID primitives to be supported by the tag are enumerated with RFID macros, or assembly-like descriptions of the tag operations. From these, the RFID preprocessor generates templates automatically. The behavior of each RFID primitive is specified using ANSI C in the template. The resulting file is compiled by the RFID compiler. A smart buffer sits between the transceiver and the tag controller, to detect whether incoming packets are intended for the tag. By doing so, the main controller may remain powered down to reduce power consumption. Two System-on-a-Chip implementation strategies are presented. First, a microprocessor based system for which a C program is automatically generated. The second includes a block of lo...
