Floating point math

Hello,this would be my first real job with fpga, and because of that, i need some help. Originally i was using STM32F4 to make single point DFT from 128 point array, but even at 250MHz it is too s...

Sure, you can do all that in an FPGA if you like.

You're FPGA design would consist of three major parts:

1. the ADC/detector timing generation and sample acquisition

2. the floating point arithmetic

3. the external processor interface

Are you looking for pointers to "getting started" tutorials etc. or did you already have some specific questions?

Since the title of the thread you created is "floating point math", here is a pointer to the Altera-supplied floating point arithmetic modules, which are free to use:

The core of your algorithm would likely consist of simply chaining together the correct series of blocks. i.e. your STM32F4 MAC instruction would require the ALTFP_MULT followed by ALTFP_ADD_SUB with necessary glue logic and registers in between.
