Can golang be used for hardware development?

golang can be used for hardware development. As a compiled language, it is still very advantageous in hardware programming. Golang is specially optimized for the programming of multi-processor system applications. Programs compiled with Go It is comparable to the speed of C or C code, is more secure, and supports parallel processes.

The operating environment of this tutorial: Windows 10 system, GO version 1.20, Dell G3 computer.

Can the go language develop intelligent hardware?

go language is the most emerging language. Of course, it can also develop hardware, and go language development hardware also has many advantages. As a compiled language, go language has the same performance as C The languages ​​​​are almost the same, and the Go language is still very advantageous in hardware programming.

What is Go?

Go language is the second open source programming language released by Google in 2009.

The Go language is specially optimized for programming multi-processor system applications. Programs compiled using Go can be as fast as C or C code, are more secure, and support parallel processes. Not only can you develop the web, but you can also develop the underlying layer. Currently, Zhihu is developed using golang. The preferred language of the blockchain is go, Ethereum, and Hyperledger are all based on the go language, as well as the go language version of btcd.

The goal of Go is to improve the dependence of existing programming languages ​​on libraries and other programs ( dependency), these software elements will be called repeatedly by the application. This language is also designed to solve multi-processor tasks due to the existence of parallel programming models.

Google has high hopes for Go. Its design is to allow the software to take full advantage of the simultaneous multitasking of multi-core processors and to solve the troubles of object-oriented programming. It has modern programming language features, such as garbage collection, to help programmers deal with trivial but important memory management issues. Go is also very fast, almost as fast as C or C programs, and can quickly create programs.

Go's website was built using Go, but Google has greater ambitions. The software is specifically designed for building server software (such as Google's Gmail). Google believes that Go can also be applied to other areas, including executing software in the browser and replacing the role of JavaScript.

Why should you learn GO language? What are the advantages of GO?

1. What are the advantages of Go?

Advantages of Go

1: Performance

2: The language performance is very good IMPORTANT

3: Developer Efficiency & Don’t Be Overly Innovative

4: Concurrency & Channels

5: Fast Compilation Times

6: Build a Team Capabilities

7: Powerful ecosystem

8: GOFMT, mandatory code format

9: gRPC and ProtocolBuffers

can be directly compiled into machine code , does not rely on other libraries, the version of glibc has certain requirements, and deployment is completed by throwing a file up.

A statically typed language, but with the feeling of a dynamic language. A statically typed language means that most hidden problems can be checked out during compilation. The feeling of a dynamic language is that there are many packages that can be used and written. high efficiency.

The language level supports concurrency. This is the biggest feature of Go. It is born to support concurrency. I once said that there is a difference between innate genes and plastic surgery. Everyone is equally beautiful, but you still like plastic surgery. What about innate genetic beauty? Go supports concurrency in its genes. It can make full use of multiple cores and make it easy to use concurrency.

Built-in runtime supports garbage collection. This is one of the characteristics of dynamic languages. Although GC is not perfect at present, it is enough to cope with most situations we can encounter, especially Go1.1 GC after that.

Simple and easy to learn. The authors of the Go language all have C genes, so Go naturally has C genes. Then Go keywords are 25, but the expression ability is very powerful and almost supports most of your other applications. Features seen in languages: inheritance, overloading, objects, etc.

Rich standard library, Go currently has a large number of built-in libraries, especially the network library is very powerful, and this is my favorite part.

Built-in powerful tools. There are many tool chains built into the Go language. The best one should be the gofmt tool, which automatically formats the code and makes team review so simple. The code format is exactly the same, but the thinking is different. It's all very difficult.

Cross-platform compilation. If the Go code you write does not contain cgo, then you can compile Linux applications on the window system. How to do it? Go references the code of plan9, which is information that does not depend on the system.

Embedded C support. As mentioned earlier, the author is the author of C, so Go can also directly include c code and make use of the existing rich C library.

2. What is Go suitable for?

Server programming, if you used C or C to do those things before, Go is very suitable to do it, such as processing Logs, data packaging, virtual machine processing, file systems, etc.

Distributed systems, database agents, etc.

Network programming, this area is currently the most widely used, including Web applications, API applications, download applications,

In-memory databases, the former For a period of time, Google developed groupcache and part of couchbase

Cloud platform. Currently, many foreign cloud platforms are developed using Go. It was partly established by CloudFoundy and the former VMare technical director himself came up with the apcera cloud platform.

3. Go’s successful projects

nsq: bitly’s open source message queue system has very high performance. Currently, they process billions of messages every day

docker: A virtual packaging tool based on lxc, which can realize the establishment of PAAS platform.

packer: used to generate image files for different platforms, such as VM, vbox, AWS, etc. The author is the author of vagrant

skynet: distributed scheduling framework

Doozer: Distributed synchronization tool, similar to ZooKeeper

Heka: mazila open source log processing system

cbfs: couchbase open source distributed file system

tsuru: open source PAAS platform, and The functions implemented by SAE are exactly the same

groupcache: a caching system written by the author of memcahe for the Google download system

god: a caching system similar to redis, but supports distribution and scalability

gor: Network traffic packet capture and replay tool

4 , Go’s other shortcomings

The following shortcomings are some of the problems I encountered during project development:

Go’s import package does not support versions, and sometimes upgrades can easily cause problems in the project. It is not runnable, so you need to control the corresponding version information yourself

Once Go's goroutine is started, switching between different goroutines is not controlled by the program. When scheduling runtime, strict logic is required, otherwise the goroutine will sleep. The logic ends for a period of time, and then suddenly appears and is executed again, which will lead to logic errors and other situations.

The GC delay is a bit large. The log system I developed was damaged once. When the concurrency was very large, the GC was not that fast and the memory recycling was not effective when processing large logs. Later, after the profile program was improved, has been improved.

The image processing library under pkg has many bugs. It is better to use mature products. The interface of calling these mature libraries imagemagick is more reliable.

Finally, I recommend everyone to learn Go. This language is really worth it. Everyone should study hard, because it can do any work from the bottom to the front end.

5. Application of go

The application direction of Golang:

Blockchain technology: referred to as BT

Blockchain technogology, Also known as distributed ledger technology, it is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records.

Backend server application:

Supports the backend traffic of the main website (sorting, recommendation, search, etc.), provides load balancing, cache, fault tolerance, conditional distribution, and statistical operation indicators Meituan

Backend applications of cloud computing/cloud services:

CDN’s scheduling system, distribution system, monitoring system, short domain name service, CDN internal open platform, operation report system and other small tools.

golang, which is the full name of the go language we are familiar with. Go language is the second open source programming language released by Google. Specifically optimized for programming multi-processor system applications, programs compiled using Go can be as fast as C or C code, are more secure, and support parallel processes.

The Go language is mainly used for server-side development. It is positioned to develop "large-scale software". It is suitable for many programmers to develop large-scale software together. It has a long development cycle and supports cloud computing network services. The Go language allows programmers to develop quickly, and as the software continues to grow, it makes it easier for programmers to maintain and modify it. It combines the efficiency of traditional compiled languages ​​with the ease of use and expressiveness of scripting languages.

As a server programming language, Go language is very suitable for processing logs, data packaging, virtual machine processing, file systems, distributed systems, database agents, etc.; in terms of network programming, Go language is widely used in Web applications and API applications. , download applications, etc.; in addition, the Go language can also be used in the field of memory databases and cloud platforms. Currently, many foreign cloud platforms are developed using Go.
