I would like to compute an 8k FFT with the FFT Accelerator and I would like to spend not almost all intern memory. Speed is not so important for this application. If I configure the FFT accelerator with the Expert Code Generator, I need several buffers which have in total more than 80 thousand float values (2.4 Mbit memory).
Is it possible to reduce the required memory size? (real data input)
Is it possible to place some buffers in the external memory?
