During system architecture exploration phase, the software code will not be available or processor models to execute code is not available or the number of boards required is too expensive. To overcome this challenge, VisualSim has a profile-based software generator. This generator takes into consideration the list of tasks and the percentage of the different types of instructions- integer, floating-point, fixed-point, load-store, move, memcopy, branch, mispredict and complex math.
