A system and method for determining the placement of software functions at link time is disclosed. The system utilizes special annotations that are included in software modules of the source code, which defines certain parameters associated with each function. These parameters may be referred to as code classification components, wherein each code classification component may include one or more code classes associated with that code classification component. These software modules are then compiled. A linker script is created based on the desired configuration. The linker then uses the linker script to determine which software modules should be placed in RAM for improved execution speed.
