What are the requirements of embedded system?
Requirements for Devices Around Us: Embedded Systems, Part 2
- Performance. A real-time system must satisfy the timing needs and constraints of the operating environment.
- Efficiency.
- Reliability.
- Robustness.
- Safety.
- Security.
- Usability.
What are the requirements for software of embedded systems and its features?
Microprocessors based − It must be microprocessor or microcontroller based. Memory − It must have a memory, as its software usually embeds in ROM. It does not need any secondary memories in the computer. Connected − It must have connected peripherals to connect input and output devices.
What are the features of embedded system?
Characteristics of Embedded Systems
- All Embedded Systems are task specific.
- Embedded systems are created to perform the task within a certain time frame.
- They have minimal or no user interface (UI).
- Some embedded systems are designed to react to external stimuli and react accordingly.
What are the functional requirements of an embedded system?
Functional requirements may involve calculations, technical details, data manipulation and processing, and other specific functionality that define what a system is supposed to accomplish. Behavioral requirements describe all the cases where the system uses the functional requirements, these are captured in use cases.
