Design of systolic B~N circuits in Galois fields based on quaternary logic

【摘要】 The BNoperation is known as an efficient basic operation in Galois fields GF(2k),and various algorithms and implementations using binary logic signals have already been proposed.In order to reduce the circuit complexity and long latency of BNoperations,a novel algorithm and its systolic architecture are proposed based on multiple-value logic(MVL).In the very large scale integration(VLSI)realization,a kind of multiple-valued current-mode(MVCM)circuit structure is presented and in which the combination of dynamic source-coupled logic(SCL)and different-pair circuits(DPCs)is employed to improve the switching speed and reduce the power dissipation.The performance is evaluated by HSPICE simulation with 0.18μm CMOS technology.The transistor numbers and the delay are superior to corresponding binary CMOS implementation.The combination of MVCM circuits and relevant algorithms based on MVL seems to be potential solution for high performance arithmetic operationsin Galois fields GF(2k).更多还原
