Syntax directed translators intermediate

A Syntax – directed translation scheme is a convenient description of what we would like done.
The output defined is independent of the kind of parser used to construct the parse tree or the kind of mechanism used to compute the translations.
A Syntax – directed translation scheme provides a method for describing an input-output mapping, and that description is independent of any implementation.
A SDD is a context free grammar with attributes and rules.
A Syntax-directed translator is to use extra fields in the parser stack entries corresponding to the grammar symbols.
