AbstractWe propose to design and fabricate a high-performance convolver integrated circuit, that can be coupled to a digital stochastic neural network classifier. Our architecture is optimized for image processing, and has a predicted single-chip performance of 50 billion multiply/accumulates per second. Unlike competing neural network integrated circuits, this throughput can be maintained with realistic chip I/O bandwidth. This high performance is achieved at the architecture level by exploiting massive parallelism in computing several convolution kernels simultaneously, and at the circuit level by using compact mulitplying D/A converters (MDACs) and analog current summing. We propose to research and develop custom integrated circuits that will support the construction of large, high performance neural networks. Our Phase I effort will include the design AND FABRICATION of a small-scale prototype CMOS integrated circuit to prove the feasibility of our development. Our approach will utilize commercial CMOS/bulk integrated circuit technology; products arising from this R&D can be fabricated reliably and economically by a number of vendors. We have previously demonstrated components for the core technology, and propose to augment the architecture with support for real-time, on-chip learning algorithms. The proposed research applies our expertise in mixed-signal design techniques and neural network architectures.
