FPGA vs. CPU, what is FPGA

FPGA is a CPU package.

An FPGA is a chip that can be programmed to change its internal structure。Generally, FPGA engineers will use the hardware description language Verilog or VHDL to "program" the FPGA, and then go through the synthesis, layout, and wiring of the FPGA development tools (Diamond or Radiant) provided by the manufacturer to generate a bit file or a bin file.

Advantages of FPGAs:FPGAs are composed of hardware resources such as logic units, RAM, and multipliers, and hardware circuits such as multipliers, registers, and address generators can be realized by rationally organizing these hardware resources. FPGAs can be designed using block diagrams or VerilogHDL, ranging from simple gate circuits to FIR or FFT circuits.

FPGAs can be reprogrammed indefinitely, loading a new design in a few hundred milliseconds, and using reconfiguration can reduce hardware overhead. The operating frequency of the FPGA is determined by the FPGA chip and the design, and some demanding requirements can be met by modifying the design or replacing the faster chip (of course, the operating frequency is not unlimited and can be increased, but is limited by the current IC process and other factors).

FPGA (Field-Programmable Gate Array) is a product of further development on the basis of programmable devices such as PAL, GAL, and CPLD. It appears as a semi-customized circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of gates of the original programmable devices.

FPGA is a field-programmable gate array technology, which is a technology based on the principle of digital electricity, and learning FPGA requires a certain foundation of digital circuits.

The brief introduction of the FPGA is as follows:

1. FPGA (FieldProgrammableGateArray) is a product further developed on the basis of programmable devices such as PAL and GAL. It appears as a semi-custom circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of gate circuits of the original programmable positive devices.

2. FPGA design is not a simple chip research, but mainly uses the FPGA model to design products in other industries. Through the analysis of the global FPGA product market and related suppliers, it has a very important role in promoting the overall improvement of China's scientific and technological level.

The brief introduction of the chip is as follows:

Integrated circuit is a way to miniaturize circuits (mainly including semiconductor equipment, but also passive components, etc.), using a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit on a small piece or several small pieces of semiconductor wafers or dielectric substrates.

It is then encapsulated in a tube shell to become a miniature structure with the desired circuit function. All the components have been formed into a whole in terms of structure, which makes the electronic components a big step towards micro-miniaturization, low power consumption, intelligence and high reliability.

It is a miniature electronic device or component, denoted by the letter "IC" in a circuit, and its inventors are Jack Kilby (integrated circuits based on germanium (Ge)) and Robert Noyce (integrated circuits based on silicon (Si)).

Most of the applications in today's semiconductor industry are silicon-based integrated circuits, which are a new type of semiconductor devices developed from the late 50s to the 60s of the 20th century.

The differences between MCU and FPGA are:

1. FPGA is more inclined to hardware circuits, which are chips used to design chips (trapped FPGA). The process of customizing an integrated circuit on an FPGA chip via a hardware programming language.

2. The single-chip microcomputer is biased towards software, and is designed and developed on the chip (single-chip microcomputer) of the existing solidified circuit. The execution of software instructions on the hardware chip is described through software programming and language description.

FPGAs and microcontrollers are characterized by:

1. Features of FPGA:

By using FPGA to design ASIC circuits (application-specific integrated circuits), users can get suitable chips without chip production.

FPGAs can be used as pilot samples of other fully custom or semi-custom ASIC circuits.

The FPGA has a wealth of flip-flops and IO pins inside.

FPGAs are one of the devices with the shortest design cycle, lowest development cost, and lowest risk in ASIC circuits.

FPGA uses a high-speed CMOS process with low power consumption and is compatible with CMOS and TTL levels.

2. Features of single-chip microcomputer:
