The difference between FPGA and MCU

What are the differences between FPGA and microcontroller?

The main differences between FPGA and microcontroller are as follows:

1. Speed: Since FPGA is a hardware circuit, its running speed directly depends on the speed of the crystal oscillator, and the system is stable, especially suitable for high-speed interface circuits. However, because the microcontroller is single-threaded, the program statement needs to wait for the single-chip microcomputer cycle to be executed, so the running speed is relatively slow.

2. Essence: The difference between FPGA and microcontroller is essentially the difference between software and hardware. FPGAs are more inclined to hardware circuits, while microcontrollers are more biased towards software.

3. Application: MCU is widely used in various fields such as embedded systems, smart homes, smart electronics, automotive electronics, medical equipment, etc. Because FPGA is a logic unit, it is easy to execute in parallel, which is suitable for places with a large amount of computation, but a single computation method, such as video processing, network processing, etc.

4. Difficulty of entry: Compared with FPGA, the design and entry of MCU are relatively simple, and the price is lower.

It should be noted that FPGA and microcontroller are not mutually replaceable in practical applications, but choose suitable devices according to specific application requirements.
