Space-Pope posted:not much more to say. it was done over a couple of FPGA boards. did 32-bit addition/subtraction and multiplication, with the multiplier on the second board People used to do this with transistor circuits piled up to build logic gates. FPGAs are magic and I love them. Xilinx?

echinopsis posted:love dat story about the fpga and the evolutionary thing that made something work but only due to manufacturing defects and something and not just actual circuitry I don't know this story!! Also RS232 is 3 wires (2 if you only need to send data one way). RS232 is easily the most robust serial interface standard, unless you want to talk about it's high voltage siblings. I'd post a cool picture of the amazing LIM crate setup at SLAC end station A, but iPhoto is horrible and is stupid.

Xilinx is a literal pile of poo poo however it is weird magic poo poo that is the most powerful thing in the world.
