Abstract

This study introduces a neural network-based system designed to expedite the classification of handwritten characters, particularly focusing on numbers. Utilizing a perceptron that aggregates weighted inputs followed by a non-linear function, the system estimates the likelihood of a character being any digit from 0 to 9. The implementation, achieved through Very-Large-Scale Integration (VLSI) and programmed using Verilog, adopts a tree structure that saves over one thousand clock cycles compared to a serial approach in the addition phase. It requires 393 clock cycles for the system to accurately recognize a single digit. This research presents a practical approach to handwritten character classification. The system has potential applications across various handwriting resources, including images, paper documents, and touchscreen inputs. Further studies could broaden its utility by extending recognition capabilities to letters and symbols, enhancing its applicability in educational and scientific domains where quick and precise character recognition is crucial. Such advancements could significantly benefit sectors requiring efficient data digitization and processing from handwritten sources.
