N2 - A general purpose low cost hardware ANN system has been built. The hardware is based on MD1220 Neural Bit Slice and PC/AT is used as the host computer for testing. Each MD12201 contains 8 binary neurons. In order to improve its connectivity and flexibility, Time Division Multiplexing (TDM) is used. This approach can allow network reconfiguration for different architectures by simply changing the firmware instead of modifying the hardware. Here, back propagation learning paradigm2 is selected for evaluating the system and a primitive OCR application was designed to test its functionality and feasibility. The results of this work are reported which indicate the implementation of neural network architectures using a conventional computer such as in the assembly code of 80286 may require 24 times more clock cycle than MD1220 assuming that the same clock (20MHz) is used. Further analysis also indicates that the TDM approach will be a low cost and effective way of implementing the hardware ANN system. This is especially important for embedded controller application.
