Public Software

Published Software in general can be found in our Github Account

For various publications, we develop a modified NVM Simulator. In addition, we perform certain memory analysis on the simualtor output, espcially semantic memory analysis.

We also developed tools for evaluating the effect of errors stemming from unreliable memories on the inference accuracy of artificial neural networks. We provide a tool for error tolerance evaluation of binarized/quantized NNs.  For applying error models on more general NNs, we created the tool BFITT which applies error models to PyTorch tensors.
