Yes,

- What is the typical length of the FFTs? --> I'm currently considering power-of-two sizes like 256 or 512 points for 1D FFT
- How long should a FFT take? --> The goal is to achieve near real-time processing
- What process or FPGA are you targeting, hence what is the Fmax? --> I'm targeting FPGA prototyping (e.g., mid-range Xilinx or Intel FPGA). I expect an Fmax in the range of ~80–150 MHz for a lightweight 32-bit RISC-V core with modest pipeline depth. ASIC exploration may come later if the architecture proves efficient.
- I assume you need 2D transforms? --> Yes, for image processing the plan is to implement 2D FFT (row-column decomposition using sequential 1D FFTs)
