Abstract :
An electronic neurocomputer, Neuro Turbo, has been implemented, using the recently developed general-purpose, 24-bit floating-point digital signal processor (DSP), MB86220. The Neuro Turbo is a MIMD (multiple-instruction-multiple-data) type parallel processor with four ring-coupled DSPs and four dual-port memories. The performance of the Neuro Turbo has been evaluated for several kinds of three-layer neural network. An operational speed of 2 MCPS for the learning process and 11 MCPS for the rewarding process has been achieved
