FPGA (Field-Programmable Gate Array), or Field-Programmable Gate Array, is the product of further development based on programmable devices such as PAL, GAL, and CPLD. It emerged as a semi-custom circuit in the field of Application Specific Integrated Circuit (ASIC), which solves the shortcomings of custom circuits and overcomes the shortcomings of the limited number of gates of the original programmable devices.

FPGA (Field-Programmable Gate Array), or Field-Programmable Gate Array, is the product of further development based on programmable devices such as PAL, GAL, and CPLD. It emerged as a semi-custom circuit in the field of Application Specific Integrated Circuit (ASIC), which solves the shortcomings of custom circuits and overcomes the shortcomings of the limited number of gates of the original programmable devices.


Applications

Circuit Design

Connection logic and control logic are the early areas where FPGAs play a large role and are the cornerstone of FPGA applications. In fact, the application of FPGAs in circuit design is still relatively difficult, which requires developers to have the appropriate hardware knowledge (circuit knowledge) and software application skills (development tools) are always in short supply, often engaged in the development of new technologies, new products will become the mainstream of the market base products for product designers to apply in the near future, the design of general-purpose and specialized IP will become a hot industry! A popular industry! The prerequisite for circuit design is to have a certain amount of hardware knowledge. At this level, dry more than learning, of course, a quick start is very important, the better the bit is not waiting for people circuit development is a golden rice bowl.


Product design

The relatively mature technology applied to certain specific areas such as communications, video, information processing and so on to develop products that meet the needs of the industry and can be accepted by industry customers This aspect is mainly a combination of FPGA technology and professional technology issues, there is also the interface with professional customers Product design also includes professional tools products and civilian products, the former focus on performance, the latter price sensitive product design to FPGA technology is a means to achieve the main purpose of product functionality in this field, FPGA because of the interface, control, functional IP, embedded CPU and other characteristics have the conditions to achieve a simple structure, high degree of solidification, comprehensive function of the system product design will be the most extensive market for the application of FPGA technology, with great explosive demand space product design requirements for technical personnel The road is also long, but now the whole industry is in the state of forming the "first team", as long as you join, the future is bright product design is a career development direction positioning, not simply a hobby can do! The field of product design will create a large number of companies and entrepreneurs, is a development hotspot and opportunity.


System level

System-level application is the combination of FPGA and traditional computer technology to achieve a FPGA version of the computer system, such as the use of Xilinx V-4, V-5 series of FPGA, embedded POWER PC CPU, and then with a variety of peripheral functions to achieve a basic environment, in this platform to run LINUX and other systems, the system also supports a variety of standard peripherals and functional interfaces (such as graphics interface) which is very helpful for the rapid composition of the FPGA large system. This "cottage" flavor of the early advantages of the system may not be very obvious, similar to the situation of the ARM system, but if we can slowly play out the advantages of FPGA, and gradually achieve some characteristics of the system is also a development direction. If the system-level applications, developers do not have the ability to expand the development of the system, just engage in programming is of little significance, of course, the development of device drivers is another case, engage in system-level applications seem to start high, but do not have the ability to develop deep, it is likely to become enthusiasts, as many people will do web pages but can not be called programming. Similar to the above are a few personal views, I hope to help people who want to learn FPGA but are very confused to sort out their ideas. This is a good industry with good opportunities for personal success. But also certainly a very competitive industry, the key is to look at the speed and depth and of course the ability to adapt to the market.


The biggest difference between FPGA and other ASIC chips is its programmable feature. FPGA is almost a jack of all trades in the communication field, what FPGA can do depends largely on the user's design ability.


Wireless area.

Since FPGA itself is embedded with a processor (SOPC), its application is more extensive. Some specific application aspects such as: for implementing speech synthesis, error correction coding, baseband modulation and demodulation, and system control; and for implementing baseband modulation and demodulation functions; timing recovery, automatic gain and frequency control, symbol detection, pulse shaping, and matched filters, etc. However, because the wireless field requires a large number of complex mathematical operations, the requirements for FPGAs are very high.


Wired domain.

From WAN and MAN to mobile backhaul access networks and xPON-based access networks, FPGAs can provide a full set of solutions for rapid product development. Such as the current MSTP products, from PDH to SDH, from EoP to EoS, all functions are available FPGA implementation; such as PTN products, its OAM, QoS, PTP, Ethernet protocol conversion, etc.; and OTN products, from ODU to OTU, as well as SAR, Interlaken, Fabric, etc.. As well as the current access to the mainstream technology XPON products, many functions can be achieved with FPGAs.
