Abstract
Binary translation is often used in migrating legacy binaries to
new architecture based platforms. This paper describes a static
binary translator which translates ARM binaries to a MIPS-like
architecture designed for embedded systems. The static translator
handles basic architecture translations and performs optimizations
to minimize instruction overhead. The conditional execution
feature in the ARM architecture requires special attention on
binary translation and optimization. With several optimizations to
minimize condition updates and checks, the translated code from
ARM to our target architecture increases the instruction path
length by only 35% on the EEMBC benchmark.
