摘要
当前摩尔定律已遇到瓶颈,通用处理器的计算能力受到制约,而深度学习等新型企业计算对数据中心服务器功耗和计算性能提出了更大的挑战。现场可编程门阵列(FieldProgrammable Gate Array,FPGA)具有高性能、低功耗等特点,FPGA异构计算平台可有效解决数据中心能效问题。文章阐述了FPGA异构计算平台的硬件体系结构和软件编程模型,分析了基于Open CL的FPGA异构计算平台的高性能、低功耗、动态可重构等优势。应用实践表明,FPGA异构平台可在降低系统功耗的同时提升系统性能,从而实现系统能效的有效提升。
Moore＇s law encounters a bottleneck today. Computing power of the general purpose processor is restricted. At the same time, new types of enterprise computing such as deep learning bring more challenges to the power consumption and computational performance of the data center. FPGA has the advantages of high performance and low power consumption. FPGA heterogeneous platform can effectively solve the energy efficiency problems of the data center. In this paper, the hardware architecture and software programming model of FPGA heterogeneous platform are introduced first. Then advantages of this platform are analyzed. The applications of FPGA heterogeneous platform show that it can improve the system performance while reducing the system power consumption, so as to achieve the effective improvement of the system energy efficiency.
