  • Chenfan Sun
  • Published 2016


Popcount is a binary operation where the input is a binary word and the output is the number of set bits. Popcount is a common building block for many applications such as the Hamming distance calculation. Recently, popcount is used to approximate multiplications in convolutional neural networks. Considering renewed interest in popcount, this work asks the… (More)
