How to interface output of an analog-to-digital converter to a computer?

I am running an experiment in which I require the output of an I/Q modulator to be interfaced with my computer. I am planning on using an analog to digital converter IC, with a sampling speed of at least 20 Mhz.

My question now is, how do I interface the output of an ADC (like the AD9461) to my computer? Since I am dealing with such fast sampling rates, I want to know how to do so without bottlenecking effects.

Would a microcontroller be the best solution here?
Thank you for your help!

Hi Messario,

Some user also ask that query, you could check out these links.

1. ADC to PC interface circuit
2. Interface 20-Bit Sigma-Delta ADCs Through A PC's Parallel Port

Hope it helps,

Most PCs are not good at doing real time processing, you have two bottle necks, hardware and software. Direct access to the PCs bus would overcome the first, there are solutions around for that, it is a high speed serial bus in today's PCs. Then you have to deal with the operating system, and what you actually want to do with the software. It is possible that using the GPU may be a workable solution depending on the sort of processing power you need. Whatever you do, you will need quite a bit of hardware and software expertise to solve this problem, you really need to talk to someone working in this sort of area. Incidentally, why does it have to be a PC? Use a DSP processor, and pipe the processed data to a PC, probably solve most of your problems.
