¿µ¹®³»¿ë¿ä¾à | This standard defines CPS services to support when it is difficult to satisfy the quality attributes required by physical elements due to performance limitations of computing resources in a CPS environment. In addition, it presents components and interfaces of a reference model to guarantee WCET(Worst Case Execution Time) by executing services that require real-time among CPS services in an optimal device. Through the two-step scheduling structure presented in this standard, the real-time performance of a specific service can be provided. | ||
