一、引言随着社会信息量的激增,信息处理系统得到了急速的发展,其主要目标是缩短高速计算系统的计算时间。例如,在从人造卫星送回来的图象信息处理、核反应堆的等离子模拟、全球气象分析以及飞机设计中的空气动力学计算领域中,计算量都非常大,目前采用Si IC的最高速的大型计算机的运算速度是10～30MIPS(MIPS——每秒100万条指令),巨型计算机是100MFLOPS(MFLOPS——每秒100万次浮点运算)。如果以这样的计算速度计算上述应用中的问题,花费时间就相当长,有时甚至用几天到几十天。因此,需要开发处理能力比现在大千倍的(10BFLOPS,BFLOPS——每秒10亿次浮点运算)特高速计算机。
I. INTRODUCTION With the surge of social information, the information processing system has been rapidly developed. Its main goal is to shorten the calculation time of high-speed computing system. For example, in the field of image information processing from satellites, plasma simulations of nuclear reactors, global meteorological analyzes and aerodynamic calculations in aircraft design, the amount of calculations is very large. Currently, the largest high-speed computers using Si ICs The computing speed is 10 ~ 30MIPS (MIPS - 1 million instructions per second), the giant computer is 100MFLOPS (MFLOPS - 1 million floating point operations per second). Calculating the problems in these applications with such computing speed can take quite a long time, sometimes even days to tens of days. As a result, there is a need to develop very high speed computers (10BFLOPS, BFLOPS - 1 billion floating point operations per second) that are capable of processing more than a thousand times larger than today.
