提出了一种用短ＤＦＴ芯片构成长序列ＤＦＴ的阵列协处理器的有效方法。此法易用２与，２长ＤＦＴ芯片及２４个乘法器构成２长的ＤＦＴ阵列协处理器，，也易用２ｌ＋１片，２长ＤＦＴ芯片，，２２ｌ＋１个乘法器及２个蝶形运算单元构成２＾２ｌ＋１长的ＤＦＴ阵列协处理器。文中给出了它们的并行结构及分析结果。它们具有并行计算度高，芯片需求少简单易实现的特点。
In this paper.an efficient method for constructing array co-processors for onedimensional DFT was proposed. With it.we can construct an array co-processor for 22t points DFT with 2'chips (2'points per chip) and 22tmultiplication units; and an array co-processor for 22t+1 points DFT with 22t+1 chips (2t points per chip) , 22t+1 multiplication units and 22' butterfly operation units.
