Editing Embedded operating system (section)

== Design ==
Embedded systems comprise a [[Processor (computing)|processor]] and corresponding [[software]]. [[Embedded software]] requires storage for [[executable]]s and temporary data processing during [[Runtime (program lifecycle phase)|runtime]]. Embedded systems typically utilize [[ROM]] and [[RAM]] as [[main memory]] components. For functionality, embedded systems necessitate input and output interfaces. [[Embedded hardware]] configurations are often unique, varying according to the application.<ref>{{Cite journal |last1=Sager |first1=P.

The choice of embedded operating system, which organizes and controls the hardware, often dictates the additional required embedded hardware components.

Software developers might write essential code in [[assembly language]] to harness the full processing power of the [[central processing unit]] (CPU). Assembly language, being ''machine-efficient,'' can enhance speed in [[deterministic system]]s but may reduce [[Portability (computer science)|portability]] and [[maintainability]]. Frequently, embedded operating systems are coded in portable programming languages like [[C (programming language)|C]].
