Systems and methods are provided for a multi-die dot-product engine (DPE) to provision large-scale machine learning inference applications. The multi-die DPE leverages a multi-chip architecture. For example, a multi-chip interface can include a plurality of DPE chips, where each DPE chip performs inference computations for performing deep learning operations. A hardware interface between a memory of a host computer and the plurality of DPE chips communicatively connects the plurality of DPE chips to the memory of the host computer system during an inference operation such that the deep learning operations are spanned across the plurality of DPE chips. Due to the multi-die architecture, multiple silicon devices are allowed to be used for inference, thereby enabling power-efficient inference for large-scale machine learning applications and complex deep neural networks. The multi-die DPE can be used to build a multi-device DNN inference system performing specific applications, such as object recognition, with high accuracy.
