The 1-bit serial version is 2100kGe (excluding registers). Their talk claims the 4-bit variant is 2.5x larger (while being 4x faster) which is around 5250kGe. Add in all the registers and you get pretty close to that 13kGe number (assuming you're using 31 registers instead of 15 in the 32e spec).
- kragen 2y agothank you for the extra context! i had assumed they were using the 1-bit serial version and that for whatever reason they just needed a lot more gates than anyone had expected from fpga simulations. i didn't realize serv had a nybble-serial option, and that's a very significant difference. so it's closer to 1000× the energy consumption of off-the-shelf microcontrollers than 5000×
