What is FPGA chip?

FPGA chip is a programmable logic chip, also known as the “Field-ProGramMable Gate Array”.Unlike a fixed -function chip, the FPGA chip has flexible and variable functional characteristics. It can “programming” chips to achieve the functions you want according to the user’s needs and design.

FPGA chip structure

The FPGA chip is mainly composed of the search table (LUT), storage unit, clock controller, I/O drive, digital signal processor and other basic units.The search table is the most basic unit of FPGA. The main function is to find the corresponding output in the search table based on the logic information of the input, and connect the output to other units to form complex circuits.

The application field of FPGA chip

FPGA chips are widely used in many industries, such as computers, communication, automotive, medical, industrial automation and other fields.In the computer field, FPGA chips can be used for applications such as high -speed parallel computing, physical simulation, and image processing.In the field of communication, FPGA chips can be used for protocol conversion, decryption, signal processing, etc.In the medical field, FPGA chips can be used for medical imaging information processing or in vitro monitoring.

Advantages of FPGA chip

The FPGA chip has the advantages of strong flexibility, low power consumption, high updated, low development costs. These advantages make FPGA chips in many areas to replace traditional fixed functional chips; and as the FPGA chip process continues to improve, its performance and applicationThe scope will be further expanded.

FPGA chip design process

The design process of FPGA chips mainly includes steps such as environmental construction, RTL design, comprehensive, layout wiring, simulation and other steps.The order of the steps may be different, but the basic design process is roughly the same.Among them, RTL design refers to transforming demand into specific hardware circuits through hardware description language (such as Verilog, VHDL).


The difference between FPGA chip and ASIC chip

FPGA chips are different from ASIC chips (special integrated circuits). The ASIC chip has a fixed hardware circuit and cannot be changed. The FPGA chip can change its hardware circuit at any time.The design process of ASIC chips is relatively complicated and requires independent development of the EDA tool, while the FPGA chip uses high -end EDA tools, and the development threshold is low.

FPGA chip manufacturer

At present, the global FPGA chip market is mainly divided by two giants from Xilinx and British Altera (after acquisition by Intel).However, in China, there are some good FPGA manufacturers, such as Achronix and Matrix, which also have a certain market share in China.


The price of FPGA chip

Because the production cost of FPGA chips is relatively high, the price is relatively expensive.Generally speaking, the price of FPGA chips is several times or even tens of times more expensive than traditional fixed -function chips.However, most manufacturers provide basic and cheap development boards for ordinary users and beginners.

Future development of FPGA chip

My point of view is: FPGA chips have significant advantages such as strong flexibility, good updates, and low power consumption. With the continuous progress of technology, the scope of technology and application will continue to expand.In the future, FPGA chips, as new electronic devices, will play an increasingly large role in the fields of artificial intelligence, the Internet of Things, machine learning.
