A retargetable compiler for the generation of control routines of a microprocessor-based digital system

A retargetable compiler by using a hybrid interpretative/table-driven code generation scheme is described. The rapid development of computer architectures and microprocessors has created an urgent need for the retargetable compiler. The retargetable compiler has the following advantages in designing microprocessor-based digital systems; (a) designers need not learn any microprocessor assembly languages; (b) it is easy to translate programs to a new microprocessor-based digital system. The UNCOL model of J. Strong, et al. (1958) and a general framework for retargetable compilers are discussed, the three most popular retargetable code generation methods are compared, and a hybrid interpretative/table-driven code is proposed. An implementation for the EMSAIL language is described.<
