1. 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 coupled together to form a first communication fabric, and a second communication fabric, wherein the second communication fabric includes a serial bus; 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 communicates with each other to perform a real time operation, wherein executing the plurality of applications includes copying, from an input of an isolator cell, data that includes a plurality of data elements to an output of the isolator cell; sending a command to a master task by a system controller via the serial bus included in the multiprocessor system; initiating application swapping by the master task in response to receiving the command from a system controller; and swapping the first application of the plurality of applications with a second application; wherein swapping the first application with the second application includes continuing execution of each application of the plurality of other applications, and in response to determining the first application is upstream to the isolator cell, repeatedly sending, by the isolator cell, previously stored data from one or more buffers included in the isolator cell, to an application downstream of the isolator cell; and wherein upon completion of the swapping, the plurality of other applications continues to execute with the second application, and wherein at least a subset of the plurality of other applications communicates with the second application to perform the real time operation.
