Hi, I am newbie in VHDL and FPGA. I am implenting a project 64-FFT(16
bit precision) of radix-4 with FPGA. As I have no detailed knowledge of
those, I am facing some problems:

1. converting real numbers(between -1 to +1) in binary to use in vhdl
code for arithmatic operation.
2. I made a behavioural block for Radix-4, But I am not sure whether I
can use it for synthesing with FPGA( as I did not use any mult/adder,
only arithmatic operations!)

May be these questions are funny, but still I need to know. Please
someone help me, or give some alternative ideas.

Thanks all.
