Advantages and disadvantages of embedded system?

Answer 1

An RTOS is not required for an embedded system but it can offer powerful advantages to the system developer. Without an RTOS the developer must write his own code to handle all of these functions.

• Enables real-time, deterministic scheduling and task prioritization
• Abstracts away the complexities of the processor
• Provides a solid infrastructure constructed of rules and policies
• Simplifies development and improves developer productivity
• Integrates and manages resources needed by communications stacks and middleware
• Optimizes use of system resources
• Improves product reliability, maintainability and quality
• Promotes product evolution and scaling

A well-architected RTOS will handle these functions much more efficiently that a programmer could write the code. RTOS developers are expert in how to handle operations with a minimum of processor cycles.
