摘要: 为提高软件无线电(SDR)系统波形应用部署的灵活性和FPGA资源利用率,基于SDR系统的软件通信体系架构(SCA),设计一种支持FPGA的动态部分可重构(DPR)软件架构。针对DPR FPGA与CPU组成的异构计算平台,提出一种蚁群优化调度算法,以提高波形应用部署效率。实验结果表明,与MILP算法和ILP算法相比,所提算法的求解性能平均提升了约30%,且随着任务规模的增大,优势更加明显。

Abstract: In order to improve the flexibility of waveform application deployment and FPGA resource utilization in Software Defined Radio(SDR) systems, a software architecture that supports Dynamic Partial Reconfiguration(DPR) of FPGA is designed based on the Software Communication Architecture(SCA) in SDR systems.At the same time, in order to improve the efficiency of waveform application deployment, an Ant Colony Optimization (ACO) scheduling algorithm is designed for the heterogeneous computing platform composed of DPR FPGA and CPU.Experimental results show that compared with the MILP algorithm and the ILP algorithm, the proposed algorithm improves the solution performance by about 30% on average, and the solution performance grows along with the task size.

Key words: software communication architecture, dynamic partial reconfiguration, eXtensible Markup Language(XML), directed acyclic graph, ant colony optimization
