XILINX PCI development board

XILINX PCI development board

XILINX PCI development board

(OP)
What kind of board do you suggest?

I would need about 20 I/O, working at 20Mhz.
easy C++ (non windows if possible). It must tranfer about 8 Megabytes/s to PC at realtime (so some RAM buffer would be good)

I heard about Spartan, but I have read that there is few VHDL functions for spartan, perhaps wuuld be better using Virtex

I would need also to fit with a DTCXO of 20Mhz

RE: XILINX PCI development board

It is a cost and development time issue.  How much should your end product cost, and how quickly you want it ready.  Virtex parts are more expensive, but it may not matter to you if they allow for a quicker development.  Development tools, IP.  This is a complex equation.  Can you talk to a disti that has Xilinx.  Distis that carry xilinx usually have applications engineers that may help you figuring out what you need.  They may also show you competitive products like those from Altera.

In my company xilinx is used because can be used in space, but now we want an easy and quick development board. Price do not care as long as we will buy only 2 units. I would prefer Virtex.

RE: XILINX PCI development board

Just two units, the disti may not want to lose too much time with you, unless your company already had some business with them.  Then yes, Virtex would be a nice choice.  But check what your required functions are, and who carries the most of them in pre-made IP blocks.  Development time is the major parameter in your project I guess.

Fusion2022,

I am not overly versed in the FPGA to PCI developement boards, however have spent some research and developement time with the Nallatech product and have had good success. Their products are not the least expensive, but they have robust resources (VHDL and possibly C++ examples) and fairly good live support. The product I worked with was an XTEMEDSP developement board.

Good Luck, from xray

At least we bought two Cesys PCIS3BASE Spartan3 700$ board due: it has PLX PCI-9056 PCI master controller: at PLX site there is C++ code, it is unecessary to build a driver and came with a 64 i/o lines board. We have enought with its 32MB sram

If you can see PCI-9056, it controlls directly DMA and SRAM: it seems to be easy to manage.
