The goal of this work is to design a neural processor that compute in a efficient way a Feed-Forward Neural Network. It was accomplished by the design of an optimized product-sum architecture and a microcontroller based on the data flow theory. The architecture prpoposed is faster than some computer implementations like MatLab@ 4.2. Neural Network Toolbox and language "C" program. INTRODUCTIONThe main issue of this work was to develop a logical architecture that compute, in an efficient way, the equations used in a Feed-Forward Neural Network (FFNN) [l-21. First, a deep analysis was made in order to design a logical subsystem to evaluate these basic equations in the fastest way. Then, it was studied the data flow [3] within the FFNN and being proposed a bus net scheme of interconnection between the layers [4]. Finally, it was decided to use a data flow microcontroller in order to optimize the processing time and reduce the time used by the process between iterations.
