Industrial Automation
consolidation can lower total cost of ownership (TCO) by reducing the number of units requiring power and maintenance.
Consolidation requires a gateway that can simultaneously run the Microsoft Windows operating system (OS) and a real-time operating system (RTOS) supporting deterministic, real-time control applica- tions. Combining these OSs requires embedded virtualization to parti- tion platform hardware resources to keep real-time and non-real-time environments apart.

factory devices to the Internet, supporting a range of interfaces over which machines can talk (Figure 1). The most basic designs provide security and manageability features, as well as processing capabilities.
They could do much more. The scalability of Intel® processors enables
powerful gateway designs that can simultaneously handle Internet traffi c, run standard Windows applications and HMIs, and control machine operations. By consolidating these workloads on a single platform on the factory fl oor, machine manufacturers can help fac- tories reduce system hardware and software costs. In addition, such
People generally think of hypervisors or virtual machine monitors (VMMs) when considering virtualization. But this type of virtualization can limit the guest OS to the services provided by the host hypervisor or VMM and affect determinism and adaptability.
Explicit Hardware Partitioning Embedded virtualization implemented through “explicit hardware parti- tioning” delivers a better solution. It dedicates processor and hardware resources to different tasks. For example, explicit hardware partitioning enables hardware isolation in a Windows-based system by using a base service expressly designed to partition the system so that real-time tasks run on the RTOS and Windows applications run on Windows (Figure 2).
Unlike solutions dependent solely upon virtual machines with hypervi- sors, explicit hardware partitioning avoids affecting the performance of either OS. The OSs, drivers, and software work without interruption, so
