Use FPGA to control the basic principle of chip

FPGA chip is a programmable logic device that can change its function by programming. Compared with ASIC (special integrated circuit), it is more flexible and more adaptable.At the same time, for some specific application scenarios, FPGA chips can control its operation by connecting different chips to achieve more functions.

The difference between FPGA and traditional control chips

The traditional control chip, such as a single -chip microcomputer, built the control logic inside the chip during design to achieve the specified function.The FPGA chip can write a program through the designer to change its internal logic circuit, thereby achieving different functions.Therefore, the FPGA chip can provide more flexible and changeable functions and more efficient performance.

Cyclone II FPGA

Use FPGA to control the advantages of the chip

By connecting FPGA with other control chips, a very efficient control system can be achieved.This system can flexibly configure different logical circuits according to needs to achieve different functional needs.In addition, FPGA itself consists of multiple low -power logic blocks, so it can achieve the design of logic circuit very efficiently.

Use FPGA to control the process of the chip

Designers usually need to write code to define the logical design of the FPGA chip.They then need to connect other chips (such as processors, memory, sensors, etc.) to the pin of the FPGA chip.After completion, the FPGA chip began to perform the logic of programming.

FPGA software tool

Designers can use special FPGA software tools to help them write code.These software usually include a development kit provided by FPGA chip manufacturers, which can help designers quickly design and debug circuits.


Applicable scene of FPGA

The flexibility and high programming of the FPGA chip make it very suitable for the rapid prototype development and verification scene.It is usually used to be used to perform high -level algorithms and data processing scenarios, such as image processing, data centers, audio and video processing.

Selection of FPGA programming language

Designers can use a variety of programming languages to write the logical code of FPGA, such as Verilog and VHDL.These two programming languages are hardware description language (HDL), which is a programming language that can describe the hardware circuit.For those who first come into contact with FPGA design, Verilog is usually easier to learn.

Common FPGA chip model

Common FPGA chip models include Xilinx’s Kintex and Virtex series, Altera’s Endura and Arria series.These chips have different specifications and characteristics to meet different application needs.Therefore, when designing FPGA, you need to select the suitable chip model according to the specific application scenario.


FPGA’s future development trend

FPGA is a highly programmful chip, and its development trend in the future will be more intelligent and flexible.The design and manufacturing of FPGA chips will become more and more mature and intelligent. At the same time, it will gradually combine with technologies such as artificial intelligence to open more application scenarios.

in conclusion

Use FPGA to control the chip is an efficient, fast prototype development and flexible method.When choosing a FPGA chip, you need to choose a model that suits you according to specific application needs.In the future, the development of FPGA chips will provide more intelligent application scenarios for various industries.
