Implementation: Simulation Technology

The ``simulation technology'' is how the original machine instructions (or other source representation) gets translated into an executable representation that is suitable for simulation and/or tracing. Choices include:

Dynamic Compilation: Displaced Execution

Move an instruction from one place to another, but execute with the same host and target.

Dynamic Compilation: Cross-Compilation

Compile instruction sequences from a target machine to run on a host machine.

Hardware Emulation


Simulation and tracing tools that perform execution using interpretation; the original executable code is neither preprocessed (augmentation or static cross-compilation) nor is it dynamically compiled to host code.

Static Cross-Compilation

Statically cross-compile instruction sequences from a target machine to run on some host machine.

Static Augmentation

Augmentation-based tracing tools run host instructions native, but some instructions are simulated. For example, Proteus executes arithmetic and stack-relative memory reference instructions native, and simulates load and store instructions that may reference shared memory.

Multiple Strategies

Some tools rely on having multiple strategies in order to achieve their desired functionality. For the purposes here, ``untraced native execution'' counts as a translator.
