How to predict the memory size and gate count given source code
If you are thinking of implementing in hardware, you may want to reconsider the algorithms you use - what is appropriate for software is rarely the same as what is good for hardware.  You can of course implement exactly what you write in software, but it may be far from optimal.

(One of my day-job tasks is getting in early with algorithm people and working with them to get something at the Matlab stage which stands a chance of working well on the hardware they are wanting to target)
