Adaptive matrix multipliers

Abstract

Examples herein describe techniques for adapting a multiplier array (e.g., a systolic array implemented in a processing core) to perform different dot products. The processing core can include data selection logic that enables different configurations of the multiplier array in the core. For example, the data selection logic can enable different configurations of the multiplier array while using the same underlying hardware. That is, the multiplier array is fixed hardware but the data selection can transmit data into the matrix multiplier such that it is configured to perform different length dot products, perform more dot products in parallel, or change its output precision. In this manner, the same underlying hardware (i.e., the multiplier array) can be reconfigured for different dot products which can result in much more efficient use of the hardware.
