Getting Started with FPGAs

It&#x27;s so criminal and just rank ass terrible for this <i>amazing</i> segment of computing that it is - by and large - locked up behind incredibly hard to negotiate expensive software packages and solutions.<p>This is totally the gateway to seeing &amp; understanding what computing actually is. And there are <i>outstanding</i> and fantastic chips with all kinds of capability on offer.<p>But almost universally they require very expensive obtuse custom&#x2F;proprietary software to do anything at all. And two thirds the features on the chip require expensive IP add-ons to use from there.<p>It&#x27;s just so so so unfortunate what a ceiling there is on adoption for fpgas. So much capability and so little ability for an empoweredearned community to form around such amazing power. There&#x27;s something deeply scary to me especially about how, with fpga and RISC-V chip design in general, digital logic is cheap and plentiful, but as soon as you want interconnect or memory or io, as soon as you are looking beyond the scope of what you can do inside the scope of a chip, it&#x27;s $$$ galore to buy ways to talk to the outside world, that open chip design &amp; progress is strong but only in the confines of the digital domain.

Note also fpga4fun.com for some very practical examples on how to do common IO, or build a small network or graphics interface:<p>It&#x27;s a blast interacting with these kinds of things at the logic level!<p><a href="https:&#x2F;&#x2F;www.fpga4fun.com&#x2F;10BASE-T0.html" rel="nofollow">https:&#x2F;&#x2F;www.fpga4fun.com&#x2F;10BASE-T0.html</a>

I started my (amateur) FPGA journey on a nandland go board a few years ago. Russell&#x27;s exercises for beginners are an excellent resource.

Did anyone try out the CologneChip GateMate FPGA? It&#x27;s supposed to have a completely open toolchain, but the dev board isn&#x27;t exactly cheap at 230€<p><a href="https:&#x2F;&#x2F;colognechip.com&#x2F;programmable-logic&#x2F;gatemate-evaluation-board&#x2F;" rel="nofollow">https:&#x2F;&#x2F;colognechip.com&#x2F;programmable-logic&#x2F;gatemate-evaluati...</a>

I started dabbling with FPGAs but having issues finding boards with open toolchains and high* speed peripherals (ethernet and&#x2F;or PCIe), for now I&#x27;m using the Gowin boards with Yosys but they are not the best to get started

This board:<p><a href="https:&#x2F;&#x2F;digilent.com&#x2F;reference&#x2F;programmable-logic&#x2F;zybo-z7&#x2F;start?srsltid=AfmBOopnYfNXfAlTBuzRTskhRmE6SILBJ5nO5NUZ0Wd9GdvaNiru_xQk" rel="nofollow">https:&#x2F;&#x2F;digilent.com&#x2F;reference&#x2F;programmable-logic&#x2F;zybo-z7&#x2F;st...</a><p>Because the chip is a processor and FPGA, you can use the FPGA for doing tests and processing without complicated interfaces. Both access the RAM and can work with it!

I was wondering - if I was to use 2 high resolution (4Mpix each) screens (lvds or mipi), create &quot;Li-fi&quot; like transceiver 20+ Mbps and have ability to decode at 60+ FPS video streams - is there a single simple SoC that could handle this? Or still need FPGA?

It looks fun, until you run into the closed vendor-enforced tooling.
