Dynamic binary translation in a type-II hypervisor for Cavium Octeon MIPS64 based systems

摘要

Dynamic binary translation (DBT) has been used in various applications that range from system-level virtualization to cross-platform application execution. It has also been used in kernel profiling/tracing and security applications. In this paper, we discuss multiple DBT strategies that were implemented during the development of a type-II hypervisor for Cavium Octeon MIPS64 based systems, along with their pros and cons. Poor timing performance of virtualized system was the major reason for re-factoring different design strategies. Our current block-level dynamic binary translation has proven to be better among the others.
