- lnsru 8y agoDoes it make sense? Xilinx AC701 or an older Altera Arria V dev Kit have all the hardware for this. Writing code for them might be interesting learning project, but there are more interesting stuff nowadays to learn.
- metaphor 8y agoNot sure what Arria V dev kit you're referring to, but the AC701 retails for ~$1.3k and is overkill for the target application.
- lnsru 8y agoWhat do you want to pay for it? Hardware alone might cost 300$, but you also need somebody that wants work for free. 900$ is realistic price assuming low demand for such niche application. Maybe even higher price like this one: https://numato.com/product/nereid-kintex-7-pci-express-fpga-development-board https://numato.com/product/nereid-kintex-7-pci-express-fpga-... I am not related to Numato, but getting 4k@60Hz requires mid range chip like this Kintex-7. I also not sure, if somebody wants to open source more than schematics and Gerbers after putting few hundred working hours in such project.
- metaphor 8y agoCertainly not anything remotely close to $1k with unnecessary baggage. Where did you pull this imaginary 4K@60Hz performance requirement from anyways? The original article discussed analog VGA with PCI host control. The GP said something similar. You're proposing high-bandwidth digital video and suggesting native PCIe dev boards...completely out of scope. Take a look at the i.MX6 Rex project[1] designed by Robert Feranec and Martin Murin before presuming what people out there are willing to release. Comparatively speaking, a VGA over PCI video card is solo undergrad EE fodder. [1] https://www.imx6rex.com/ https://www.imx6rex.com/
