摘要：

In this paper, a hardware solution for multi-objective differential evolution (MODE) algorithm is presented. The proposed hardware is developed as a co-processor and interfaced with PowerPC440 processor of Virtex-5 field programmable gate array to accelerate execution speed on an embedded platform. It is validated by optimising four standard benchmark functions and its execution time is compared with the same algorithm running on a 32-bit PowerPC440 processor. Further, as a case study, the proposed hardware is used to solve Spectrum Allocation (SA) problem in Cognitive Radio Network (CRN). In CRN, the available licensed channels are assigned to cognitive users using SA task while satisfying the multiple objectives posed by licensed users. The MODE core is integrated with the SA objective functions and developed as a MODE-based SA (MODE-SA) co-processor on an embedded platform for distributed CRN. The MODE-SA core has attained a speedup of 50-60× compared to the PowerPC440 implementation. Copyright © 2017 Inderscience Enterprises Ltd.
