What can FPGAs do, what FPGAs are

FPGAs have a lot of functions, mainly using Verilog or VHDL to write logic, which is similar to C, but more straightforward than C (because it is hardware-oriented). Everything that can be done in C can be done with FPGAs, such as controlling other hardware as a CPU (chips with various functions you can think of, such as ADDA); Able to perform ** image processing; Due to their high speed, FPGAs are also widely used in the field of communication.

However, because the FPGA is internally connected with or non-logical, the multiplication is slower, much worse than the DSP, if you use the FPGA for multiplication, it is recommended to use a hard-core multiplier. In addition, it is recommended to make more use of soft IP to improve efficiency.

Circuit design currently done in hardware description language (Verilog or VHDL) can be simplified.

Single synthesis and layout, fast programming to FPGA for testing, is the mainstream of modern IC design verification technology. These components can be used to implement basic logic gates (e.g., AND, OR, XOR, NOT) or more complex combinations such as decoders or mathematical equations. In most FPGAs, these components also contain memory elements such as flip-flops or other more complete memory blocks.

System designers can connect the logic blocks inside the FPGA as if they were connected as needed, as if a breadboard were placed in a chip. The logic blocks and connections of a factory-finished FPGA can be changed according to the designer, so the FPGA can perform the required logic functions. FPGAs are generally slower than ASICs (Specialized Integrated Chips), cannot complete complex designs, and consume more power.

But they also have a lot of advantages, such as being able to produce products quickly, being able to be modified to correct errors in the program, and being cheaper. Vendors may also offer cheaper, but less capable FPGAs. Because these chips have relatively poor capabilities, the development of these designs is done on a common FPGA, and then the design is transferred to an ASIC-like chip.

Another way is to use CPLD (Complex Programmable Logic Device).

There are still many research fields, such as communications, automotive electronics, intelligent AI, military equipment, and so on. The specific work can be done FPGA software development, FPGA software verification, chip development, chip verification, etc.

FPGA (Field Programmable Gate Array) is a product of further development on the basis of programmable devices such as PAL and GAL. 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.

Unmanned aerial vehicles, large-screen splicing systems, mobile phones, automotive unmanned driving assistance systems, intelligent monitoring, data centers, aerospace electronic equipment, 5G communications, military communications, big data processing, industrial control.

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.

FPGA (Field-Programmable Gate Array) is a programmable gate array that can be used for digital circuit design and embedded system development.

FPGAs are more flexible and customizable than ASICs (Application Specific Integrated Circuits) because FPGAs can be programmed to achieve a specific function, while ASICs need to be designed and manufactured by chips. In addition, FPGAs have faster development cycles and lower development costs, making them more suitable for certain application scenarios.

The basic building blocks of an FPGA are the Programmable Logic Cell (CLB), which consists of a logic gate, memory, and flip-flops. The logic unit of the FPGA can connect the logic gates into the appropriate structure according to the programming requirements, so as to implement complex digital logic circuits. The FPGA also includes input and output pins (IOs) and clock management circuitry for communication and coordination with the external environment.

FPGAs have a wide range of applications in digital signal processing, communication, image processing, autonomous driving, industrial control and other fields. For example, FPGAs can be used to achieve high-speed data acquisition and processing, so as to achieve real-time control, real-time image processing, encryption and decryption, and other functions. In autonomous vehicles, FPGAs can be used to enable efficient sensor data acquisition and processing while ensuring low latency and high reliability.

In the field of communication, FPGAs can be used to implement codecs, modems, signal processing and other processors to improve communication speed and reliability.

Although FPGAs show excellent performance and flexibility in some application scenarios, they also have their drawbacks, such as limited resources, high power consumption, and complex programming. For some high-performance applications, ASICs may still be a better choice.

In conclusion, FPGA is a programmable gate array with high flexibility and customizability, which is widely used in digital circuit design and embedded system development, which has important practical significance.
