Process-Level Virtualization for Runtime Adaptation of Embedded Software

Free registration required

Executive Summary

Modern processor architectures call for software that is highly tuned to an unpredictable operating environment. Process-level virtualization systems allow existing software to adapt to the operating environment, including resource contention and other dynamic events, by modifying the application instructions at run-time. While these systems are becoming widespread in the general-purpose computing communities, various challenges have prevented widespread adoption on resource-constrained devices, with memory and performance overheads being at the forefront. In this paper, the authors discuss the advantages and opportunities of run-time adaptation of embedded software.
