Embedded systems are dedicated computer systems that perform specific functions within larger mechanical or electrical systems and often operate under real-time constraints. They differ from general computing systems in that they are application-specific, typically embedded in devices like digital watches and MP3 players, and run firmware stored in ROM or flash memory. Key characteristics include low cost, small size, high reliability, and the need for responsiveness to the physical environment.
Embedded Software Development
- 4. An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. Embedded systems control many devices in common use today. Definition Hard to Define Computing Systems embedded within electronic devices Nearly any computing system other than a desktop computer
- 6. An Embedded system is a specific to a application, whereas a computer system is generic. Though the components are same there is substantial difference in them. A personal computer is not designed to perform a specific function, rhather it is able to do many things. The essential difference is that a computer when manufactured is in blank state, the manufacturer does not know what the customer will do with it, while an Embedded system is application specific. An Embedded system is a component within some large systems If required each of the embedded systems are connected by a sort of a communication network. Numerous embedded systems make up the computer system.
- 13. It is designed to do some particular task. Embedded systems are not always standalone devices. The program instructions written for embedded systems are referred to as firmware and are stored in ROM or flash memory chips.
- 15. Timeliness - Even infinitely fast computer embedded software needs to deal with time because the physical processes with which it interacts evolves over time. Concurrency - Engage with the physical world where multiple things happen at once. Liveliness - Program must not terminate or block waiting for events that will never occur. Heterogeneity - Different computational styles and implementation technologies interact with events occurring. Reactivity - React continuously to the environment at the speed of the environment. Reliability and security - The system must be reliable and secure against errors. Interaction with physical devices - The communication of embedded systems is performed through unusual i/o devices that sometimes require signal conditioning. Robustness - The conditions of the embedded systems operation may be adverse, so they must be as robust as possible.
- 17. Low cost Small size High reliability Fast operations Easy to manufacture Fewer interconnections Portable, such as digital watches, mp3 player, etc Real time response No user interface Not much data storage
- 19. C has been the language of the embedded programmers. It is fairly simple to learn, compilers are available for almost every processor in use today. C which is considered as a middle level language having both the constructs of the low- level as well as high-level, has all the rich features in it that makes it the choice of the embedded programmers. C is not the only language used by embedded programmers there are other languages like Assembly language C++ Ada These languages though exists did not gain popularity as C.
- 21. Hardware products for National Instruments embedded systems share a common architecture that includes three components: an embedded controller for communication and processing; an FPGA for advanced control, timing, signal processing, filtering, and custom protocols; and industrial I/O modules for connectivity to any sensor or device. All of the components are reconfigurable through a single software toolchain.
