Ever increasing complexity and power dissipation in digital wireless communication systems, researchers have focused on RFID towards low power and high integration density for area reduction. In this paper we implement a RFID system using 'single spin technology' which will be smaller in size, fast, less power consumption and thereby, allows longer working hours between tag and reader and make larger interrogation zone.

Due to the simplicity of scheduling, the buffered crossbar is becoming attractive for high-speed communication system. Although the previously proposed Round-Robin algorithms achieve 100% throughput under uniform traffic, they can not achieve a satisfactory performance under non-uniform traffic. In this paper, we propose an efficient Round-Robin scheduling algorithm based on binary-tree scheme where service policy is applied to improve Quality-of-Service. With the proposed scheduling algorithm, the searching time-complexity of O(1) (one clock cycle) and 100% throughput under non-uniform traffic can be obtained. Based on a binary-tree structure, the design achieves high-speed data rate at Tbps, and simpler design with combinational circuits. The design has been simulated on both FPGA-based (Virtex 5) and Silicon-based technology (0.18 um). The synthesis results show that consumed resources varied from 11 to 533 slices and from 46 to 1686 2-NAND gates for crossbars of size 4x4 to 128x128. Critical path delays from 0.72 to 4.52 ns for FPGA-based and from 1.33 to 4.0 ns for silicon-based have obtained for the design.
