A protection domain system is implemented to provide protection for applications executing in a computing environment. Protection domains are allocated system resources and may contain executing tasks. The protection domain system may allow tasks to access resources in other protection domains to which attachments have been made. Attachment is transparent to the software developer. The protection domain system provides flexibility in implementing operating system services and defining protection hierarchies.

Protection domains for a computer operating system

A project analysis system and method is described to allow for automated generation of scalable bootable applications and downloadable applications, preferably in connection with an integrated development environment (IDE). The project analysis system and method includes facilities for automatically identifying and including software components in application development projects based on symbol dependencies and component dependencies. The project analysis system and method also includes facilities for automatically identifying and removing software components in application development projects where no symbol dependencies or component dependencies exist, thereby removing unused code. A graphical user interface is provided for user display and selection of includable and excludable components.

System and method for implementing a project facility

A method and system are disclosed for autoscaling, i.e., determining if an application program or an operating system within a system project uses components that are not already included within the system project ('needed components'). A user of a project facility is shown these needed components and allowed to select the components that are to be added to the system project. Autoscaling may also determine the components that are not used by the application program or the operating system ('deadwood components') but still present in the system project. These deadwood components are displayed to the user and the user is allowed to remove them from the system project.
