What exactly is an FPGA layman s point

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

In layman's terms, an FPGA is a programmable hardware chip.

Circuit design completed in hardware description language (Verilog or VHDL) can be quickly programmed to FPGA for testing after simple synthesis and layout, which is the mainstream technology of modern IC design verification. 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.

Basic features: 1) The ASIC circuit (application-specific integrated circuit) is designed by FPGA, and the user can get the right chip without chip production.

2) FPGA can be used as a pilot sample of other fully customized or semi-customized ASIC circuits.

3) FPGA has abundant flip-flops and IO pins inside.

4) FPGA is one of the devices with the shortest design cycle, the lowest development cost and the least risk in ASIC circuits.

5) FPGA adopts high-speed CMOS process, low power consumption, and can be compatible with CMOS and TTL levels.

It can be said that FPGA chips are one of the best choices for low-volume systems to improve system integration and reliability.

This thing is very fashionable now, IC design companies have to take FPGA for experiments, and then do ASIC design after success, automotive electronics companies recruit FPGA engineers a lot... But if you want to eat this meal, you not only have to do verilog、Data collection,But also learn the basic knowledge of communication、C language well...

You're right, things like microcontrollers can be implemented through FPGAs, such as embedding 51's IP core in FPGA, and you can program 51 like 51 in this module.

FPGA is implemented from the gate level design, and the design industry of digital circuits is based on this, so it can be said that FPGA can theoretically realize all the functions of digital circuits, of course, its pertinence is not strong, unlike 51, there are special serial communication interruptions, etc. It is important to use different processors according to the design requirements in practical applications, so that you can complete the design quickly and easily. In general, it is mostly implemented by multiple processors working together, such as a FPGA and a single-chip microcomputer.

FPGA 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.

FPGA design is not a simple chip research, but mainly uses the FPGA model to design products in other industries. Unlike ASICs, FPGAs are widely used in the communications industry. Through the analysis of the global FPGA product market and related manufacturers, combined with the current actual situation in China and the leading FPGA products in China, we can find the development direction of related technologies in the future, which has a very important role in promoting the overall improvement of China's scientific and technological level.

FPGA is an integrated chip based on digital circuits and belongs to a type of programmable logic device (PLD).

FPGA is between software and hardware, and when it is used as an interface and communication, it is biased towards hardware. Using it for algorithms and control, it is biased towards software. With the rise of artificial intelligence and machine vision, FPGAs are more heterogeneous in software algorithms and have the potential to compete with GPUs.

Software Direction:Focusing on software development, we develop FPGA acceleration application capabilities in data analysis, artificial intelligence, machine vision and other fields, and mainly use OpenCL and HLS technologies to achieve software and hardware collaborative development.

Hardware Orientation:Focusing on logic design, it focuses on FPGA's application design, integrated circuit design and chip verification capabilities in specific fields.

The initial application field of FPGA is the field of communication, but with the development of the information industry and microelectronics technology, FPGA technology has become one of the hottest technologies in the information industry, and the application scope has expanded, covering aerospace, automotive, medical, broadcasting, test and measurement, consumer electronics, industrial control and other hot fields, and with the development of technology and technological progress, it has begun to penetrate into life from all angles.

In recent years, programmable gate array (FPGA) technology has developed rapidly, and its high flexibility has made it more and more widely used in communication (5G), data processing, network, instrumentation, industrial control, military, aerospace, integrated circuits, artificial intelligence and other fields. In the field of digital IC design, front-end verification work is generally done with FPGAs, so FPGA engineers are also urgently needed talents for IC design companies. FPGA IC logic design and development has become one of the most promising industries at present, especially for FPGA system engineers who are familiar with hardware architecture.

Industry insiders believe that there is a talent gap of at least 20-300,000 in the FPGA IC design industry, and the demand for FPGA hardware developers in the Beijing market alone has exceeded 30,000, and it continues to increase. There are two main reasons for this: first, the current professional settings of colleges and universities rarely involve FPGA and IC design courses, and even if there are, they are biased towards theory, so it is difficult for enterprises to recruit practical talents; Second, FPGA and IC design requires a hardware environment and a lot of practice to accumulate experience.

Without proper guidance, there are many detours to take. The system masters the FPGA development technology, and can be independently competent in FPGA system hardware design, logic design, FPGA combination system design, etc. Consumer electronics, industrial control, military enterprises, telecommunications, network communications, aerospace, automotive electronics, medical equipment, instrumentation, integrated circuits, artificial intelligence and other industries.

FPGAs are field compilable gate arrays. To put it simply, it is to give you a stack of blocks, you can according to the unique shape or characteristics of the blocks, put together any shape by yourself, to achieve your work, of course, it may be limited by FPGA software or hardware rules, but compared to other hardware such as single-chip microcomputer, the degree of freedom and flexibility are still relatively high. f

FPGA is quite useful and has a wide range of applications, such as aerospace, commercial, and military industries.

FPGA is a chip that can reconstruct circuits and is a hardware reconfigurable architecture. Its full English name is field programmable gate array, and the Chinese name is field programmable gate array.

Now the development prospects are very good, and computer-related majors are more suitable to consider a career.

Reconfigurable chips are widely used in communication comprehension.

It is a semi-finished circuit template, which is suitable for layout in basic hardware language.

Logic circuits currently described in hardware description language (Verilog or VHDL) can be quickly burned to FPGA for testing using logic synthesis and routing tool software.

It can be done very quickly, and its internal logic can be repeatedly modified by the designer to correct errors in the program.

As a result, in some industries where technology is changing relatively quickly, field-programmable gate arrays are almost a necessary component in electronic systems, as they must quickly capture the market before a large number of products can be offered. This is where the convenience and flexibility of FPGAs come into play.
