Software Implementation for Multi-Protocol 13.56 MHz RFID Reader
Young Do, Sanghoon Lee, Sangeon Park · IEICE Transactions on Communications · 2008
In this paper, we design and implement a multi-protocol 13.56MHz reader in software. In order to satisfy the timing constraint, three level optimizations called compile level, syntax level, and architectural level optimizations are applied. The execution time of optimized code is reduced by 85%, so that it satisfies timing requirement of a 60MHz speed EISC processor. In addition, the binary code size is minimized to 211KBytes which can be loaded on a 256KB size memory.
