Digital neural network processor for consumer goods, games, telecommunications or medical equipment or vehicle

摘要

The processor represents weight- and activity values of the neural network as floating point values of small bit width. A required MAC operation is integrated in processing units. Floating and fixed point representation is used alternately. Format changes are performed through multiplexers as well as through activity functions. A weight memory, in which weight values are stored, is associated with each processing unit, so that they are addressable through a counter. Several processing units are summed up to processing unit groups. Each group contains a control logic and a dual activity memory. These processing unit groups are controlled by a global control logic.
