Compilers[This slide is by John Werth.]

A compiler translates language X to language Y; ``language'' is understood very broadly:

• Compile a program to another program. High-level to machine language is the original definition of compiler.
• Compile a specification into a program.
• Compile a graph into a program.
• Translate one realization of an algorithm to another realization.
• Compile a program or specification to hardware.
