摘　　要：FPGA因其强大的运算能力成为了众多高性能应用的最佳选择,但其传统的开发方法存在门槛高、周期长等众多不足。OpenCL作为跨平台的开发语言,为FPGA提供了一种全新的开发方法。此方法开发周期短、抽象层次高、可移植性强,弥补了传统开发方式的不足。介绍了OpenCL开发FPGA的相关优化方法,以矩阵乘法和QR分解为例,深入分析了各种优化方法的优缺点及适用情况。FPGA becomes the best choice for many high performance applications because of its powerful computing capabili- ties. But its traditional development methods have many deficiencies,such as high threshold,long cycle and so on. OpenCL pro- rides a new method for FPGA development,as a cross-platform development language.Doe to its short development cycle,high level of abstraction and strong portability, it makes up for the deficiencies of the traditional development methods. This paper presents the development process of FPGA using OpenCL and its optimization methods.Taking matrix muhiplication and QR decomposition as example,the advantages and disadvantages of various optimization methods and their application conditions are analyzed thoroughly.

关 键 词：FPGA OPENCL 矩阵乘法 QR分解
