Subject: [oc] Help with choosing a FPGA
Let me start off by saying that I am sorry if some of my questions
seem a bit basic, but my knowledge of FPGA’s is limited to a few
classes I took back when I was in school.
My ultimate goal is to capture data from a CMOS image sensor and store
it to a hard drive. The CMOS sensor itself will either be clock out
data at a frequency of 48Mhz or 96Mhz. My first question is how can I
tell if a particular FPGA is capable of reading in data at these
rates? I have looked over various datasheets but I have to admit I
have not been able to find a straight answer.
The two devboards I am looking at are the “Spartan 3E Starter Board”
from Dililent or the “Cyclone II FPGA Starter Development Kit” from
Altrea. Would either of these boards be capable of doing what I need?
As for cores I am thinking that I will need to run the following:
OpenRISC 1200
General-Purpose I/O (GPIO) Core
I2C controller core
tri-mode Ethernet MAC
VGA/LCD Controller
OCIDEC (OpenCores IDE Controller)
Does any of this sound reasonable for the boards I mentioned above or
do I need to go back to the drawing board?
