Acoustical Cellular Automata Parallel Processor

Motorola Flash Innovation 2003 – Design Contest
First Prize

Raymond Weisling


The mathematical concept known as cellular automata (CA) is primarily modeled as a two-dimensional graphical presentation. Humans have the ability to localize sound sources in two and even three dimensions due to the physical shape of the human head and ears. Thus, we have the ability to discern the position of the sounds around us. The Acoustical Cellular Automata Parallel Processor applies cellular automata to a two-dimensional array of sound emitters. The design uses multiple microcomputers connected in a two-dimensional array to form a larger parallel array processor. The array processor, built with the 68HC908QY4, is programmed to handle the specific case of CA with multiple sound emitters to display the cell states. The microcomputer module actually controls four cells in the array, and is connected to four sound emitters (transducers). The module can be connected to other modules to form a large array that could conceivably cover a wall.
