超高速单片FFT处理器

Ultra-high Spead One-chip FFT Processor

本文重点介绍了一种超高速单片FFT处理器TMC2310,并且详细讨论了我们所研制的开发系统。该系统采用计算机和TMC2310构成的主从结构,具有良好的编程控制能力。存贮器采用乒乓存贮结构,使系统工作可以连续进行。该系统可在470μs内完成1024点复数FFT变换,比单片C30快7倍,比C25快20倍以上。

This paper first presents a ultra-high speed one-chip FFT. processor-TMC2310, then its development system is discussed in details . The system has a master-slave architecture of computer and TMC2310 , and is easy to program . In order to work concurrently , the memory of the system has a switch-bank architecture . The system can run 1024-points complex FFT in 470μs, its transform speed is 7 times faster than that of single TMS 320C30 and 20 times faster than that of Single TMS 320C25.
