This unprecedented level of security is achieved by implementing multiple secure cells, operating in user mode, under the control of a hypervisor that operates in privileged mode
, which allows the development and configuration of a system running in completely virtualized yet protected spaces without requiring access to privileged mode
at any point.
Support for unmodified guests, such as Windows, is made possible by Intel's VT technology, which provides a privileged mode
of execution that allows Xen to share platform resources between both modified and unmodified guest operating systems, providing CPU, memory and I/O resource guarantees.
The new privileged mode
and a memory protection unit enable easier porting of real-time operating systems and the convergence of several embedded applications on a single StarCore processor core.
The new MIPS32(TM) and MIPS64(TM) architectures incorporates previous MIPS(R) instruction set architectures, or ISAs, add new more powerful instructions, and expand the MIPS(R) standard to include privileged mode
and kernel operations used in operating system software.
In Chretien's cosmology, night figures prominently and forms the sphere within which the privileged modes
of transference and inclination toward some other may be felt.
