What are the differences between ARM, DSP and FPGA? [Copy link]

ARM, DSP, and FPGA are the most commonly used industrial control chips and even IoT application chips. So what are the similarities and differences between these three chips in principle? Which chip has the most powerful function? What are the differences in functions, mainly referring to the functions of the pins and the expansion capabilities supported?

Your question is too huge, just like the universe. ARM carries the system, DSP does the algorithm, and FPGA does high-speed sampling.

What does ARM with system mean? Can it be used as an operating system? Why can't the other two? Isn't this the difference?
