Software tool for program transformation from Motorola 68HC11 to 68HC08 microcontrollers

Abstract

This contribution deals with design of software conversion tool dedicated for M68HC11 program equipment transformation to new Motorola's microcontroller family M68HC08 which became a new 8-bit industry standard including number of new advantageous features. The main problem is that these new microcontrollers are not object code compatible. Therefore number of up to now created program equipment for M68HC11 can not be directly used on M68HC08. One way how to solve program transfer from M68HC11 on this new generation of microcontrollers is to design universal software tool transforming each instructions of M68HC11 program code to macros, which will have same function as original instruction and can be processed with same results by M68HC08 central processing unit. © 2004 IFAC.
