RP2040/2350 are IO monsters. You could for example make a logic analyzer that transfers logic data through ethernet.

This "very limited" microcontroller has two cores. Both of them can execute about 25 instructions per byte for generating "application-level traffic". You could definitely saturate a 100 Mbps connection with just one core.

Now that you mention it, I think I would like to see a logic analyzer that does just that. No buffering, just straight up shovel the data to a mac address, or even IP address, and be done with it (maybe lose a few frames here and there). Let the PC worry about what to do with it, like triggers etc.

Should be cheap, right? Though 1Gbit version might still be expensive..

Can't you do reads with very basic compression faster than most of these chips can push data to Ethernet?

How is this different from the cheap salae clones now? Just sub out Ethernet for usb and that’s how they work now: a cheap ic with nothing but a2d and a usb phy samples and sends as fast as it can..

It would be over the network :), which is—I imagine—tiny bit simpler than over USB.
