Updates

May 26th, 2021

We updated the hardware description file, added off-chip bandwidth added as constraint.

We added a validation folder with data for Eyeriss and MAERI from MICRO 2019 paper.

Oct 13th, 2020

We added a direct support for GEMM layers. For more information, please take a look at here.
