註釋Embedded systems often have one or more real-time requirements. The complexity of modern embedded software systems requires a systematic approach for achieving these performance targets. An ad hoc process can lead to missed deadlines, poorly performing systems and cancelled projects. There is a maturity required to define, manage, and deliver on multiple real-time performance requirements. Software performance engineering (SPE) is a discipline within the broader systems engineering area that can improve the maturity of the performance engineering process. SPE is a systematic, quantitative approach to constructing software systems that meet performance objectives. SPE is a software-oriented approach; it focuses on architecture, design, and implementation choices. It focuses on the activities, techniques, and deliverables that are applied at every phase of the embedded software development life-cycle, especially responsiveness and scalability, to ensure software is being architected and implemented to meet the performance-related requirements of the system.
