Implementing Embedded Security on Dual-Virtual-CPU Systems
Peter Wilson, Alexandre Frey, Tom Mihm, D.J. Kershaw, Tiago M. Alves · IEEE Design & Test of Computers · 2007
In this article, we describe a low-cost, dual-virtual-CPU hardware technology for embedded-systems security. We also present a case study of a programmable software design to exploit such hardware. This design integrates a rich operating system without requiring significant changes to it, while maintaining preemptive and real-time properties, exception handling, and power management.
