UCSB ArchLab OpenTPU Project OpenTPU is an open-source re-implementation of Google's Tensor Processing Unit (TPU) by the UC Santa Barbara ArchLab. The TPU is Google's custom ASIC for accelerating the inference phase of neural network computations. Our design is based on details from Google's paper titled "In-Datacentre Performance Analysis of a Tensor Processing Unit" (https://arxiv.org/abs/1704.04760), which is to appear at ISCA2017. However, no formal spec, interface, or ISA has yet been publi...
