Software Design for a Sound Processing Embedded System

A very popular way of implementing electronic systems that perform a particular function or a field of functions is the use of embedded systems. These systems show many advantages, like their versatility and their flexibility which are very useful for the designer. In this paper, the implementation of a sound processing embedded system is described. This system receives a musical sound and then it identifies the note which is heard, as well as the musical instrument that this note comes from. The number of the musical instruments that this system can identify is two, but this number can be easily increased. Furthermore, some results concerning the function of the system are presented as well.
