Lattice Avant™-G FPGA: Boot Up Time Demo (12.12.2023)

https://www.youtube.com/watch?v=s4NUVYyLUxc



CertusPro-NX has I/O Configuration in about 4 ms and full fabric config within 30 ms (for ~100 K logic cell device). Certus, full‑device configuration within ~ 8 ms.

Lattice make some really cool devices. Not the fastest fmax speeds, but hell if the time to config and tiny power draw don't half make up for it.


> Only 47 milliseconds from power-on to operational.

Absolute eternity by modern computer standards. GPU will be a trillion operations ahead of you before you even start. Or for another view, that's a whole seven frames at 144Hz.

People say FPGAs will be great for many workloads, but then don't give examples. In my experience the only real ones are those requiring low-latency hardware comms. ADC->FPGA->DAC is a powerful combo. Everything else gets run over by either CPU doing integer work or GPU doing FP.


That's completely besides the point. How long does an embedded linux box need to get it's GPU up and ready for number crunching? But yes, FPGAs are best-suited for deterministic low latency stuff.

With the jetsons (agx orin) I have on my desk it would take a bit of tinkering to even get it under a minute.
