1. FPGA is free, it seems that mining costs a lot of electricity, Taobao seems to sell information program before
2. Bitcoin and lettercoin are OK, but it is not recommended to buy them. There is a big risk in price fluctuation, and we have to worry about the Federal Reserve's block and capital recovery
3. Altera
since the invention of the world's first programmable logic device 20 years ago, Altera (NASDAQ: altr) has been adhering to the tradition of innovation and is the world's "system on programmable chip" (SOPC) solution advocate. Altera combines programmable logic technology with software tools, intellectual property (IP) and technical services to provide high-quality programmable solutions to more than 14000 customers worldwide. Our new proct line combines the inherent advantages of programmable logic flexibility and proct availability with higher performance and integration to meet today's wide range of system requirements
Xilinx
instry leader, the inventor of the first FPGA. Xilinx is the world's leading provider of complete solutions for programmable logic. Xilinx develops, manufactures and sells a wide range of advanced integrated circuits, software design tools and IP (intellectual property) cores as predefined system level functions
lattice
lattice semiconctor company provides the instry's widest range of field programmable gate arrays (FPGAs), programmable logic devices (PLDs) and related software, including field programmable system chips (FPSC), programmable logic devices (PLDs) and so on Complex programmable logic devices (CPLD), programmable mixed signal procts (ispPAC) and programmable digital interconnect devices (ispGDX)
in my personal experience, Altera and Xilinx now occupy half of the country in China, while other brands such as Actel and lattice occupy a small share. Altera and Xilinx provide powerful supporting tools because they are powerful. The development software of these two brands is very powerful. Personally, I feel that Altera's development software is easier to use, and its SOPC system is better. Xilinx has a large number of followers because it is the leader in the instry. Other brands also have some advantages, such as Actel is based on flash, rather than the traditional FPGA based on SRAM, but most of its tools are third-party, such as Synplicity

4. Ha ha, I think first of all, you have a wrong understanding of FPGA, whether you are specialized in researching FPGA or making things with FPGA,
1 if you are specialized in researching FPGA chips, there are only a few big companies in the United States. You can try to change your nationality first, use 10 years to think about how to enter their company, and then use 20 years to climb to the top, It is estimated that you are 50-60 years old.
2 if you do research and development with FPGA, you have to know its application direction, the development prospect of each direction and your hobbies.
in my experience, there are three development directions
1 chip, FPGA's rich logic function makes it have very strong logic test ability. Some large companies have IC design, they must strictly design their chip's ability and stability, so pre simulation and post simulation will use it. If you are interested in chip level research, you can engage in this aspect. If you want to create an IC design company, you need tens of millions of assets. The best ones in this respect are all abroad. Taiwan is not bad. There is not a good company in China. There is a blank in this instry in China
2 data acquisition function. FPGA has many IO ports. Parallel thinking is the best choice for collecting information. The photos taken by camera (CCD or CMOS) are converted into a large amount of information. You need to collect them and send them to other places for processing (such as DSP for image compression, and then send them through optical fiber), Ha ha, this is what I eat) and in the instry, monitoring the operation of the equipment all the time, collecting all kinds of change information. This is mainly used in the security instry. There are many good companies in this aspect, such as Zhejiang Dahua, Beijing Hanwang, etc., but FPGA is not very important in such companies, what they are important is the embedded function of DSP
3 embedded operating system, now the more popular embedded operating system is arm's Linux operating system. FPGA can inherit soft core and hard core. In this way, we can integrate a soft core environment to make an operating system. Most of these companies do MP3 4, as well as digital camera companies
people who understand chips are right, and few use them well. Why? Because of a word - algorithm
because those chips are just tools to accomplish your tasks, do you think hammers are important or workers' skills are important
salary, working environment and welfare can only depend on your personal ability
I've written so much. Do you know what I mean
thank you for your supplement downstairs. I have just entered this instry, and my understanding is not very comprehensive. I can only understand it with my own feelings.

5. FPGA has two directions: digital circuit design and IC Design
almost all IC designs use FPGA, which belongs to the microelectronics instry
about half of the companies in the electronics instry will use it
this is the top 100 electronic companies in China in 2010 http://www.cena.com.cn/pinpai/neibu/2010-05-25/127476474643541.shtml
it can be said that as long as companies in the electronics instry really do independent research and development, almost all of them will use FPGA

Actel mainly provides nonvolatile FPGAs. Its procts are mainly based on antifuse technology and flash technology, and its procts are mainly used in military and aerospace. Actel is a partner of the U.S. military, accounting for more than 90% of the U.S. space and aviation FPGA market. In the past decade, Actel's antifuse FPGA has been successfully applied to more than 300 space programs. These applications can prove that Actel's FPGA is beyond doubt in terms of reliability
antifuse devices are mainly used in the military market, but they are not open to the civil market, so people's impression of Actel is always looming. Until 2002, the emergence of its innovative FPGA based on flash architecture opened the mysterious veil of Actel. Since then, Actel has graally moved to the civil market, which is recognized by everyone. The first FPGA with flash architecture is proasic, which is equivalent to CPLD's single chip feature and surpasses CPLD's low power consumption and large capacity feature, and has won the praise of development engineers. More and more people use FPGA with flash architecture to replace the original FPGA of CPLD and SRAM
with the continuous change of social demand, Actel is constantly improving the technology of FPGA, and constantly improving and enriching the functions and internal resources of FPGA. In 2005, Actel launched the third generation of flash architecture FPGA -- proasic3 / e. the successful launch of proasic3 / E predicts that a new "battle" between FPGAs is about to open. The proasic3 / E series is in response to the market's demand for full function, high-performance and high-performance FPGAs Low cost FPGA is designed for the strong demand of consumer, automotive and other cost sensitive applications. The following are Actel procts:
fusion: the instry's first FPGA with analog function, integrating 12 bit AD, flash memory, RTC and other components, making SOC a reality
igloo: FPGA with ultra-low power consumption has a unique sleep mode of flash * freeze, in which the minimum power consumption can reach 5 & # 181; W. It can save the status of ram and register
igloo +: Based on igloo, I / O is optimized to provide more I / O ports, support Schmidt trigger input, hot swap and other features
proasic3l: not only has the high performance of proasic3, but also has the characteristics of low power consumption
nano: the instry's lowest power FPGA, the lowest static power consumption up to 2 & # 181; W. With 3mm * 3mm ultra-small package, 0.46 US dollar ultra-low price
these series belong to Actel's third-generation flash architecture FPGA, whose different characteristics can fully meet the needs of different markets, and bring users a lot of choices and unexpected effects to enhance the competitiveness of users' procts. Thus, Actel's third-generation flash devices naturally become a new star, Let's learn about the exciting features of Actel's third-generation flash architecture FPGA.
