FPGA as a chip

The FPGA chip is one of the most important integrated circuits in the field of modern electronic technology. It plays a vital role in the development of electronic equipment and electronic systems.From a technical perspective, the advantages and disadvantages of FPGA are very obvious, which leads to different application scope of it and other types of chips.So, what is FPGA, what is its working principle, and what are its characteristics and application areas?Next, this article will answer these questions in detail.

What is FPGA?

FPGA, called Field Programmable Gate Array, is the on -site programmable logic door array.In simple terms, FPGA is a programmable chip that can achieve arbitrary digital circuit functions through programmable logic circuits.Compared with ASIC chips, FPGA has higher flexibility and reconstruction, which can be re -programmed, so as to achieve multiple functions integration, which can greatly improve the efficiency and flexibility of circuit design.
