the Xilinx Virtex-4FX. I just finished this <a

the XC4VFX60 and the XC4VSX55. They are nice parts, but not cheap and are also
BGA's. Now with the Virtex-5's now coming out these should go down in price. <br>
<br>
I really think that a GbE card is overkill this design. A 10/100BT card might
be better using an ARM7 processor and could be done fairly easily, at lower
cost. I'll continue my research and welcome all input.<br>

<br>
Part of the idea is to be free from a local PC and free from
USB. We'll<br>
probably need the FPGA fabric since a configuration with this board<br>
probably wouldn't have an Ozy. I didn't mean to restrict it to the same <br>
I/O configuration as Ozy (e.g., a port designed to drive an SDR-1000).<br>
<br>

<br>
If a Xilinx Virtex-4FX were used as the core processor and FPGA, <br>
reference designs exist with 1 Gbps Ethernet. I suspect one of these<br>
could be leveraged (e.g., Avnet's DS-KIT-4VFX12LC at <a
href="http://em.avnet.com">http://em.avnet.com</a>).<br>
<br>
Of course, the PowerPC cores in the Virtex won't run WindowsVista, but <br>
might run MontaVista :-)<br>
<br>
Neither simple nor cheap, but perhaps interesting?<br>
