基于排序网络的大数逻辑门电路设计

Design of Majority Logic Gate Circuitry Based on Sorting Networks

  • 摘要: 针对传统大数逻辑门(Majority Logic Gate, MLG)高开销的问题, 构造了基于排序网络的MLG电路, 并以8输入的排序网络为例, 使用两个4输入排序网络、四个与门以及1个或门来实现大数逻辑值.采用VerilogHDL编写代码, 使用ModelSim仿真工具进行了功能验证.相比于传统的MLG, 该电路可以有效地缩小45.11 %的面积、降低60.43 %的功耗和减小35.44%的延迟冗余.仿真结果表明, 构造的电路可以完成正确的大数逻辑功能.

     

    Abstract: The Majority Logic Gate (MLG) has already been used to improve the reliability of memories. As to the issue of high overheads for Majority Logic Gate, a novel MLG circuitry based on Sorting Networks is proposed. An 8-input MLG example, realized in Verilog HDL and simulated by ModelSim, has been shown to explain the structure, which includes two 4-input sorting network, four and-gates and an or-gate.Compared with the traditional MLG circuitry, the proposed circuitry can reduce 45.11% area, 60.43% power, and 35.44% delay overheads respectively. The obtained results have shown that the proposed circuitry can achieve Majority Logic function rightly.
