How Does an FPGA Work?

Some of the more modern Xilinx stuff has features where you don't need to take down the whole FPGA to reload a bitstream onto part of the chip. Its really neat, you can do live reprogramming of one component and leave the others alone or have an A/B setup where one updates while the other is unchanged.

Yes, I'm working on a Xilinx ARM processor with an FPGA. The FPGA and the CPU are independent units in the chip that can each operate with or without the other. We can indeed reprogram the FPGA without taking the system down.

It goes even further. You can partially reconfigure the FPGA fabric itself: https://support.xilinx.com/s/article/34924?language=en_US

That's what I was referring to. Neat stuff.

That is really cool, hadn't heard of that before.
