Hello,
I am implementing a 128 point real Radix-2 fft, data and coefficient widths are 16 bit. I am synthezising it for use in an FPGA. However, it is taking a very long time to synthesize. (approx 3 days using Leonardo on a 2 GHz machine with 512 MByte RAM) I am using a 20K1000 Altera FPGA. The ram required by the fft will be internal to the FPGA
Will this design take up all the space on the device. From past experience, can someone give me an indication of what area of the device the fft will occupy.
Surely if it takes up most of the device, then it will be too big, as I have other features to implement in the FPGA also !!
Thank you PJ
