FPGA Computing

1.引言设计计算系统时,一个首要的折衷是速度和通用性,具体体现于系统功能的软硬件划分,即什么功能由硬件实现,什么功能由软件实现。硬件实现速度快,而软件实现灵活性大。基于此,计算系统可以分为两类:通用计算系统和专用计算系统。不同计算系统的特点集中体现于其处理部件,

Since the late 1980s,with the advent of the new kind of programmable devices named FPGA (Field-Programmable Gate Array) ,a new class of computing systems named FPGA computing systems is proposed. They possess the computing power of application-specific computing systems and the versatility of general-purpose computing systems. This paper is dedicated to FPGA computing systems. First,several representative FPGA computing systems are introduced to characterize the concept of FPGA computing. Second, some important problems in this field are discussed. At last,our current work is outlined.
