Abstract: A system for automatically generating native processor code includes a graphical designer and a compiler. The graphical designer allows a user to construct graphically a signal processing system, and the compiler receives the graphically constructed signal processing system and generates native processor code representative of the system. Also, a system for modifying input signals includes a graphical designer, a compiler, and an execution unit for receiving at least a portion of the generated code and input signals and for executing the machine code to produce as an output a version of the input signal that is modified according to the code that is representative of the graphically constructed signal processing system.
