Abstract
The aim of this work is to construct an automated migration system from software into firmware for functions or algorithms with complex logical structure. The approach is based on an already developed structured microcontrol scheme endowed with compound sequencing capabilities suitable for modular microprogramming. The basic idea is to extract, via compilation techniques, the sequencing structure of the function. This is expressed into complex firmware sequencing constructs such as modular calls and modular loops. Migration is then effected by sequence calls into microcode modules interpreting a target machine architecture on which the function is tested. The migration technique is implemented in a simulated environment consisting of several firmware design tools. The system has the option to produce firmware code suitable for PLA embodiment, thus facilitating function migration into VLSI microcode.
