To reduce many redundant convolution operations that are followed by max-pooling operations, we propose precision-cascading, where the input features are divided into a number of low-precision groups and approximate convolutions with only the most significant bits (MSBs) are performed first. Based on this approximate computation, the full-precision convolution is performed only on the maximum pooling output that is found. This way, the total number of bit-wise convolutions can be reduced by ~2× without affecting the output feature values and with <0.8% degradation in final ImageNet classification accuracy. Precision-cascading provides the added benefit of increased sparsity per low-precision group, which we exploit with zero-skipping to eliminate clock cycles as well as external memory access that involve zero inputs. By jointly optimizing the conditional computing scheme and hardware architecture, the 40nm prototype chip demonstrates a peak energy-efficiency of 8.85 TOPS/W at 0.9V supply and low external memory access of 55.31 MB (or 0.0018 access/MAC) for ImageNet classification with VGG-16 CNN.","PeriodicalId":409525,"journal":{"name":"2020 IEEE Custom Integrated Circuits Conference (CICC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116743858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
