WebAbstract: Dynamic binary translation (DBT) translates binary code from one instruction set architecture (ISA) to another (same or different) ISA at runtime, which makes it very useful in many applications such as system virtualization, whole program analysis, system debugging, and system security. Many techniques have been proposed to improve ... Webcombined a trap-and-emulate direct execution engine with a system-level dynamic binary translator to ef-ﬁciently virtualize the x86 architecture and support most commodity operating systems. By relying on x86 hardware segmentation as a protection mechanism, the binary translator could execute translated code at near hardware speeds.
