Dynamic Reconfiguration of Applications on a Multi-Processor Embedded System

A method, comprising:

• loading a plurality of applications on a multiprocessor system, wherein the plurality of applications includes a first application and a plurality of other applications;
• wherein the multiprocessor system includes a plurality of processors and a plurality of memories interspersed among the plurality of processors;
• wherein loading the plurality of applications includes distributing instructions and data from the plurality of applications among different respective ones of the plurality of memories for execution by associated processors;
• executing the plurality of applications on the multiprocessor system, wherein the plurality of applications executes together and communicate with each other to perform a real time operation;
• swapping the first application with a second application, wherein the second application is not one of the plurality of applications previously loaded and executing on the multiprocessor system, wherein swapping the first application with the second application includes continuing execution of each application of the plurality of other applications;
• performing a debugging procedure, comprising:
• determining whether the first application is executing, the second application is executing, or the first application is currently being swapped with the second application;
• and
• performing the debugging procedure based at least in part on the determination whether the first application is executing, the second application is executing, or the first application is currently being swapped with the second application.

A multiprocessor system, comprising:

• a plurality of processors;
• a plurality of memories interspersed among the processors, wherein the multiprocessor system is configured to:
• load a plurality of applications on the multiprocessor system, wherein the plurality of applications includes a first application and a plurality of other applications, wherein loading the plurality of applications includes distributing instructions and data from the plurality of applications among different respective ones of the plurality of memories for execution by associated processors;
• execute the plurality of applications on the multiprocessor system, wherein the plurality of applications executes together and communicate with each other to perform a real time operation;
• swap the first application with a second application, wherein the second application is not one of the plurality of applications previously loaded and executing on the multiprocessor system, wherein swapping the first application with the second application includes continuing execution of each application of the plurality of other applications;
• perform a debugging procedure, wherein, in performing the debugging procedure, the multiprocessor system is configured to:
• determine whether the first application is executing, the second application is executing, or the first application is currently being swapped with the second application;
• and
• perform the debugging procedure based at least in part on the determination whether the first application is executing, the second application is executing, or the first application is currently being swapped with the second application.

A non-transitory computer-accessible storage medium having program instructions stored therein that, in response to execution by a multiprocessor system comprising a plurality of memories interspersed among a plurality of respective associated processors, cause the multiprocessor system to:

• load a plurality of applications on the multiprocessor system, wherein the plurality of applications includes a first application and a plurality of other applications, wherein loading the plurality of applications includes distributing instructions and data from the plurality of applications among different respective ones of the plurality of memories for execution by associated processors;
• execute the plurality of applications on the multiprocessor system, wherein the plurality of applications executes together and communicate with each other to perform a real time operation;
• swap the first application with a second application, wherein the second application is not one of the plurality of applications previously loaded and executing on the multiprocessor system, wherein swapping the first application with the second application includes continuing execution of each application of the plurality of other applications;
• perform a debugging procedure, wherein, in performing the debugging procedure, the multiprocessor system is configured to:
• determine whether the first application is executing, the second application is executing, or the first application is currently being swapped with the second application;
• and
• perform the debugging procedure based at least in part on the determination whether the first application is executing, the second application is executing, or the first application is currently being swapped with the second application.
