FGPA = Field Programmable Gate Array. Basically, you can create a custom "CPU" for your particular workflow. Imagine the GPU didn't exist and you couldn't multiply vectors of floats in parallel on your CPU. You could use a FPGA to write something to multiply a vector of floats in parallel without developing a GPU. It would probably not be as fast as a GPU or the equivalent CPU, but it would be faster than doing it serially. Another way to put it: you can create a GPU with a FPGA, but not vice versa.
