ARMphetamine
Project to create a fast and accurate ARM processor emulator. A technique known as 'dynamic recompilation' will be used so that the highest possible speed can be achieved for emulated code - ARM code programs are translated into native code as they are being emulated. The current development platform is Linux/x86. It is possible to configure ARMphetamine at compile time to support different processor revisions and hardware models. Check...
