现在想用MSP430F5438或者MSPF5529工作在25MHz的主频下,计算1024点实数FFT运算,我想知道大概需要多长时间能够算完,有没有例程或者相应函数,谢谢!

是不是太忙了,来不及吧

建议楼主做16bit Q格式的FFT,这样可以满足大多数应用精度的要求。

First thank you for your answers.
Now I'm confused with "the Embedded Wrokbench function profiler". This is provided by TI company or others? How can I use this profile in my program? Can you give me some examples or datasheet. Thank you very much.
