Method and system for software modularization and automatic code generation for embedded systems

A tangible machine readable medium having instructions for generating reusable code modules for embedded systems, that when executed cause the machine to:

• generate code to create an embedded systems software application from one or more modules implementing specific functionality;
• develop an initialization/shutdown unit that allows for shutdown and initialization of a reusable software module for the embedded system;
• and
• develop a module proper to provide functionality of the reusable software module, the module proper having a management interface used to communicate between the module proper and one of a configuration manager and at least one configuration unit, wherein the module proper is management access type independent, and wherein code comprising the initialization/shutdown unit and module proper are provided as separate components of the systems software application.

A managed device comprising:

• at least one configuration manager;
• at least one management client to communicate with an external management application and at least one embedded systems software application module via the at least one configuration manager, the at least one management client to receive and forward requests for configuration parameter change requests, read requests and monitored variable read requests, the requests sent from a management application, and the requests forwarded to an embedded systems software application module;
• the at least one embedded systems software application module comprising:
• an initialization/shutdown unit that allows for shutdown and initialization of the embedded module;
• and
• a module proper that provides functionality of the embedded module and having a management interface used to communicate between the module proper and the at least one configuration manager, wherein the module proper is management access type independent.

A machine implemented method for generating reusable code modules for embedded systems comprising:

• generating code to create an embedded systems software application from one or more modules implementing specific functionality;
• developing an initialization/shutdown unit that allows for shutdown and initialization of a reusable software module for the embedded system;
• and
• developing a module proper to provide functionality of the reusable software module, the module proper having a management interface used to communicate between the module proper and one of a configuration manager or at least one configuration management units, wherein the module proper is management access type independent,
• wherein the developed initialization/shutdown unit and developed module proper are provided as separate components of an embedded systems software application in a managed device, the managed device to provide modular and configurable functionality, and wherein functional code of the module proper implements relevant functional algorithms for the embedded systems software application based on run-time variables, and wherein management access method dependent code is external to the module proper, thereby promoting code reusability and maintainability.
