Abstract
An operator definition fileand the like included in a source programand a compilerthat translates the source programinto a machine language programare provided. The operator definition fileincludes definitions of various fixed point type operators by class definitions. The compilercan generate effectively advanced and specific instructions that a processor executes and make improvements through expanding functions and the like without repeating frequently upgrading of the version of the compiler itself. The compileris made up of an intermediate code generation unitthat generates intermediate codes, a machine language instruction substitution unitthat substitutes the intermediate codes referring to classes defined by the operator definition filewith machine language instructions and an optimization unitthat performs optimization targeting the intermediate codes including the substituted machine language instructions.
