Method and System of Dynamic Loading of Software from External Flash

A system on-chip (SoC) comprising:

• a central processing unit (CPU);
• first memory;
• and
• hardware logic disposed within a communication path between the CPU and the first memory, wherein the hardware logic is configured to:
• perform a mirroring operation on data from a second memory to the first memory;
• receive a request from the CPU, wherein the request references an address in the first memory;
• determine whether to respond to the request using the data as stored in the first memory or the data as stored in the second memory based on whether the address referenced by the request has been written by the mirroring operation;
• and
• respond to the request.

A software programming tool comprising:

• a compiler configured to:
• produce machine code instructions and data values and to produce pseudo-addresses for the machine code instructions and the data values, further wherein the machine code instructions and the data values correspond to a software application;
• and
• a linker configured to:
• receive the machine code instructions and the data values from the compiler;
• perform a test run on the software application, including determining an execution order of a plurality of discrete software functions of the software application;
• and
• write the machine code instructions and the data values to a nonvolatile memory, including placing the machine code instructions and the data values according to the execution order of the plurality of discrete software functions.
