First, “embedded” is a concept that lacks a precise definition, with various books providing their own interpretations. However, the main idea is the same: compared to general systems like PCs, embedded systems are specialized systems, structurally simplified, retaining only the necessary parts in hardware and software while discarding the unnecessary ones. Therefore, embedded systems generally … Read more
