While developing embedded software, most designer face the problem of transferring C programs into different kind of embedded processors because the software needs to be rewritten. Hence, we propose a retargetable code generation methodology for 8051-based and PIC (Peripheral Interface Controller)-based embedded systems, namely RCGES, to generate automatically the embedded C code on retargetable embedded processors. We also present a code generation algorithm to translate C source code into the target embedded C code. After code generation, we present a verification method to verify the time constraints in a design system. In addition, we develop a graphical user interface for designers to configure the parameters of embedded processors such as timer mode, interrupt, and input/output ports, etc. Finally, three real design examples of embedded systems, normal traffic light controller (NTLC), four phases stepping motor control (FPSMC), and remote control system are used to illustrate the feasibility of the RCGES methodology.
