【摘要】 多分层系统功能的垂直迁移是改善系统全局性能的有效手段。本文以ＦＦＴ算法固化为例讨论了多层次垂直迁移的各种方案，比较了它们的结果，给出了在ＶＡＸ１１／７８５上实现的全过程以及ＦＦＴ的关键操作──蝶形计算的ＭＩＣＲＯ２微语言程序。更多还原

【Abstract】 Vertical migration of multi-layered system functions is an effective technique for improving the overall system performance. This paper discusses every method by firmwaring of FFT algorithm,and the virtues and defects of the methods are pointed out.The whole implementing process in the computer VAX 11/785 is given,and the MICRO2microprogram for the butterfly computing of FFT key operation is also presented.更多还原
