Hot updates to controller software using tool chain

A non-transitory computer readable medium including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for performing changes to current controller software while a controller is operating, comprising:

• receiving, at the controller while the controller is operating, a multidimensional delta file, the multidimensional delta file having a plurality of deltas,
• storing, while the controller is operating, the multidimensional delta file in a first location of a single memory of the controller while simultaneously executing a code segment of existing code of the current controller software stored in a second location of the single memory, wherein the multidimensional delta file is stored in an additive manner adjacent to the current controller software in the single memory;
• and
• updating a plurality of addresses associated with the single memory of the controller to correspond to the plurality of deltas based on the multidimensional delta file, without interrupting the execution of the code segment currently being executed and without modifying the code segment currently being executed, wherein the updating causes linking of execution of at least one code segment of the multidimensional delta file to the existing code of the current controller software.
