In my quick searches, I found that high speed FPGAs are around $10k+, and have much more fabric than I really need or want.
- diarmuidc 6y agoHow big is your CPU. I develop on Microsemi and the PolarFire range should do it. 12G transcievers and a decent amount of logic. At about €200+. And considering Microsemi are usually behind the curve, Xilinx and Altera must have similar https://www.microsemi.com/product-directory/fpgas/3854-polarfire-fpgas https://www.microsemi.com/product-directory/fpgas/3854-polar...
- tails4e 6y agoWhat do you intend to do with the 5GHz IO? Assuming it's for peripheral connectivity, then maybe the Ultra96 would work. It does not have general purpose transceivers availbals, but it has a PS (processing subsystem) that has lots of connectivity. The PL is pmenty big for many applications.
- Scene_Cast2 6y agoI was thinking of hooking it up to GDDR6. I've programmed an FPGA before (a couple of school projects), but never interfaced with anything serious like modern high-bandwidth memory.
- thrtythreeforty 6y agoThat would be the ECP5UM-5G parts. The 5G variants are somewhat more exotic but the base ECP5 is supported by Yosys and readily available on Mouser for $15-20 or so
