Abstract
A pre-processor is utilized to create multi-instantiated code from single instance code so that multiple copies of the single instance code can be run without changing the source code of the single instance code. Exemplary implementations include modems running multi-instantiated code, for example in a protocol stack or in a data link control element. Multiple instances of entire modem code set(s) or of portions of a modem code set can be run on the processor of a modem or on a host processor of a software modem. Another application permits a processor having no memory management unit to operate as if it had one. Another implementation enables a single task operating system, such as DOS, to run as a multi-task system. This document describes a simple method of converting ordinary single-instance software into software that supports multiple instances, each with its own data, running simultaneously on a system. This method enables multiple instance support WITHOUT modifying the original functions in the source code.
