Why do DSP always use FPGA chips

In modern electronic technology, with the popularization of digital signal processing technology, some specialized processors are also born, including DSP processors and FPGA chips.Although these two processors have different structures and uses, their combination is very common in practical applications.Especially when the DSP processor and FPGA chip are combined, the effect is more significant.This article will explore why DSP always uses FPGA chips.

What are the characteristics of FPGA chip

FPGA is the abbreviation of Field Programmable Gate Array, which is a device based on programmable logic.The FPGA chip is different from ASIC, that is, a specific integrated circuit is applied.It is a structure based on programmable logic doors, and its logic can be compared with existing programming languages.Moreover, the performance of the FPGA chip can be adjusted by repeated programming, so that using such chips can achieve great flexibility and customization.

Flexibility of FPGA chip

The FPGA chip has very high flexibility because they can be re -programmed based on specific applications.This means that as long as we can program it through specific design, we can use the FPGA chip for various applications.This flexibility is achieved on the basis of careful balance between computing resources.

Customity of FPGA chip

Another key advantage of the FPGA chip is its customization.Compared with a single ASIC (application -specific integrated circuit) design, it can be completely customized as a specific application.This is very important for achieving very open and accurate control.This customization is mainly because the FPGA chip contains a grid with a programmable logic device, which can be reconstructed as a different circuit layout from the original design.


The application of FPGA chip in DSP

In the DSP processor design, especially in measurement applications with very complex algorithms and high -precision requirements, using FPGA chips can effectively achieve performance improvement and flexibility.

DSP is a application method for digital signal processing technology. It can achieve the processing and control of digital signals, which are widely used in audio, voice, image, wireless communication, radar and other fields.However, the DSP processor’s processing of complex algorithms often takes time and resources. In addition, it is difficult to take into account low power consumption and high performance, and the assistance of the FPGA chip is required to solve it.


Examples of DSP and FPGA chips

Taking image processing as an example, for the application of video stream processing, the cooperation effect of DSP processors and FPGA chips is very significant.Taking automotive electronics as an example, car offline video streaming requires detecting sudden vehicles, pedestrians, and road signs.In this case, the DSP processor processes the signal of the video stream, and then sends the processed data to the FPGA chip, and the FPGA chip will be quickly analyzed and processed by the data to achieve a more accurate and timely detection response responseEssence

In addition to automotive electronics, the DSP processor combined with the FPGA chip can also be applied to medical, wireless communication, satellite communications, robotics and industrial automation.

in conclusion

In general, the DSP processor and FPGA chip can be used in actual applications. The DSP processor is responsible for the processing of complex algorithms, and the FPGA chip has achieved assistance and performance improvement of the DSP processor.Because the FPGA chip is flexible and customized, it has been widely used in digital signal processing and other fields, and has become the standard for DSP processors.
