MIXED-PRECISION NEURAL PROCESSING UNIT (NPU) USING SPATIAL FUSION WITH LOAD BALANCING

摘要

According to one general aspect, an apparatus may include a machine learning system. The machine learning system may include a precision determination circuit configured to: determine a precision level of data, and divide the data into a data subdivision. The machine learning system may exploit sparsity during the computation of each subdivision. The machine learning system may include a load balancing circuit configured to select a load balancing technique, wherein the load balancing technique includes alternately loading the computation circuit with at least a first data/weight subdivision combination and a second data/weight subdivision combination. The load balancing circuit may be configured to load a computation circuit with a selected data subdivision and a selected weight subdivision based, at least in part, upon the load balancing technique. The machine learning system may include a computation circuit configured to compute a partial computation result based, at least in part, upon the selected data subdivision and the weight subdivision.
