Implementing hardware design in Field Programmable Gate Arrays (FPGAs) is a formidable task. There is more than one way to implement the DSP design for FFT processor and digital FIR filter. Based on the design specification, careful choice of implementation method and tools can save a lot of time and work. There are toolboxes available to generate VHDL (Verilog) descriptions of the filters which reduce dramatically the time required to generate a solution. Time can be spent valuating different implementation alternatives. Proper choice of the computation algorithms can help the FPGA architecture to make it efficient in terms of speed and/or area.
