FPGA chip reference design

What is FPGA chip?

FPGA chip is an abbreviation of programmable door array chips. It is a digital circuit design tool based on low -level language (such as Verilog or VHDL). High degree of freedom and strong reconstruction is its biggest feature. ThereforeIn computer vision, industrial control, high -speed network, digital signal processing, embedded system and other fields.

FPGA reference design role

Spartan-7 FPGA

The FPGA reference design is a set of samples based on a FPGA chip for users to reference. Users can understand and use FPGA chips’ functions and performance to quickly develop circuit design that meets the needs.FPGA’s reference design promotes the close relationship between chip design and application, and has played an important role in reducing the application threshold and improving the industrial level.
