What is FPGA chip

FPGA (Field Programmable Gate Array) chip is a digital circuit chip based on programmable logic door circuits. Different functions of digital circuits are realized by programming on the chip.The computer application field provides data acceleration and processing functions, which has the characteristics of high flexibility, strong reconstruction, and stable performance.

The main source of power consumption of FPGA chip

The power consumption of the FPGA chip is mainly from three parts, which are static power consumption, dynamic power consumption and wiring power consumption.Static power consumption is the power consumed by the chip under power supply. The size is related to the structure of the chip; the dynamic power consumption is the energy consumption caused by the changes in the internal circuit of the chip.Power consumption is the energy consumption of capacitance and resistance on the internal signal line of the chip, and is the main source of energy consumption in the chip circuit.

Calculation method of FPGA chip power consumption

The power consumption calculation of the FPGA chip usually uses factors such as device working voltage, crystal switching frequency, and load capacity.From this, you can calculate the static power consumption, dynamic power consumption and wiring power consumption of the chip, so as to draw the total power consumption of the chip.

Factors of FPGA chip power consumption

The influencing factors of FPGA chip power consumption include: working clock frequency, working temperature, load level, the number of input and output ports, internal circuit structure and other factors.In different applications, the power consumption of FPGA chips will be different.

Application scenario of FPGA chip power consumption

FPGA chip power consumption is usually used in the fields of embedded systems, computer vision, industrial control and other fields.In these application scenarios, the FPGA chip can not only provide strong computing processing capabilities, but also maintain low power consumption, extend the battery life of the equipment, and improve the service life of the equipment.

Energy -saving measures for FPGA chip power consumption

In order to reduce the power consumption of the FPGA chip, the following energy -saving measures can be used: reducing the power supply voltage of the FPGA chip, reducing the working clock frequency of the FPGA chip, optimizing the circuit structure of the FPGA chip, and reducing the redundant logic circuit in the FPGA chip.

The choice of FPGA chip power consumption and performance

During the application of the FPGA chip, designers need to consider the choice between power consumption and performance.The lower the power consumption, the better the operating stability of the circuit, and the better the heat dissipation performance of the system; the higher the performance, to a certain extent, it can improve the operation speed and response speed of the system.Therefore, the designer needs to select the actual application scenarios to choose according to specific needs.

Analysis of the power consumption level of FPGA chip at home and abroad

At present, in the domestic and foreign FPGS chip market, FPGA chips with higher power consumption levels mainly include Intel Stratix 10, Xilinx Virtex Ultrascale+, etc. Its power consumption is usually between 100 and 400W.However, with the continuous upgrading of the manufacturing process, the power consumption level of FPGA chips is also declining.
