What is the difference between embedded and programmer?
Embedded refers to a special computer system that is application-centered, based on computer technology, and whose software and hardware can be tailored to meet the strict requirements of application systems on function, reliability, cost, volume, power consumption, etc. , and programmers are professionals engaged in program development and program maintenance.
Embedded features
1. Cutability. Architecture that supports openness and scalability.
2. Strong real-time performance. EOS generally has strong real-time performance and can be used for various equipment control.
3. Unified interface. Provides a unified driver interface for devices.
4. It is easy to operate and simple, provides friendly graphical GUI and graphical interface, and pursues ease of learning and use.
Provides powerful network functions, supports TCP/IP protocol and other protocols, provides TCP/UDP/IP/PPP protocol support and a unified MAC access layer interface, and reserves interfaces for various mobile computing devices.
5. Strong stability, weak interactivity. Once the embedded system starts running, it does not require too much user intervention, which requires the EOS responsible for system management to have strong stability. The user interface of an embedded operating system generally does not provide operation commands. It provides services to user programs through system call commands.
6. Solidify the code. In embedded systems, the embedded operating system and application software are solidified in the ROM of the embedded system computer.
7. Better hardware adaptability, that is, good portability.
8. Embedded systems and specific applications are organically combined, and their upgrades are also carried out simultaneously with specific products. Therefore, once embedded system products enter the market, they have a long life cycle.
Programmer Responsibilities
1. Responsible to the project manager, responsible for the detailed design, coding and organization and implementation of internal testing of software projects, and concurrently responsible for system analysis of small software projects Work and complete the implementation and technical support of assigned projects.
2. Assist project managers and related personnel to communicate with customers and maintain good customer relationships.
3. Participate in demand research, project feasibility analysis, technical feasibility analysis and demand analysis.
4. Be familiar with and master the relevant software technologies for delivering software projects developed by the software department.
5. Responsible for providing timely feedback to the project manager on the software development situation and making suggestions for improvement based on the actual situation.
6. Participate in the solution of major technical problems in the software development and maintenance process, and participate in the first software installation and debugging, data cutover, user training and project promotion.
7. Responsible for the formulation of relevant technical documents.
8. Responsible for analyzing and researching technological development trends in the business field.
