Address space virtualization in reconfigurable computers

ABSTRACT

Operating Systems virtualize the execution environment of a task by managing the available resources of the system. On traditional architectures a task executes on a static environment, i.e. every instant of a task will be carried upon a fixed set of physical resources. In reconfigurable computers the availability of resources and thus the physical environment upon which a task executes may vary for different executions of a task as well as during the execution of the task. The execution of a task must be independent of configuration. This paper discusses the virtualization of the address space of a task executing in a reconfigurable environment.
