Abstract
This invention provides a computer processor architecture optimized for power-efficient computation of certain sensory recognition (e.g. vision) algorithms on a single computer chip. Illustratively, the architecture is optimized to carry out low-level routines and a special class of high-level sensory recognition routines derived from research into human brain perception processes. In an illustrative embodiment, the processor includes a plurality of processing nodes, arranged in a hierarchy of layers, and the processor resolves features from sensory information input and provides the feature information as input to a lowest hierarchy layer thereof. The hierarchy simultaneously, recognizes multiple components of the features, which are transferred between the layers so as to build likely recognition candidates. Each node can further include memory constructed and arranged to refresh and retain features determined to be likely recognition candidates by a thresholding process. These are provided to an overseer that directs a function to occur.
