50 Shades of Delta Sigma

Chadi Jabbour, Antoine Frappé, Nicolas Schlegel

Delta Sigma modulators (DSM) have been around for more than 60 years. In 1962, Inose and his colleagues introduced one of the first implementations of DSM for a code modulation communication for a telemetering system. Since, during more than 6 decades, this remarkable architecture was employed to…

An In-Cell Weight Update Scheme Using One-Hot Gradients for On-Chip Learning

Mathieu Chêne, Benoit Larras, Andreas Kaiser, Antoine Frappé

In the context of edge AI, the embedded models need to be retrained on-chip. The more the backward path and the calculation the gradient (two important steps during learning) are optimized by literature, the more it becomes interesting to optimize weight update operation. This work proposes to…
