High Level Design or High Level Synthesis (HLS) helps users to design hardware at a higher level of abstraction and consequently, improve productivity and reduce costs. This methodology has gained traction in the design of custom application specific accelerators for machine learning. In this talk, Mentor’s Anoop Saha will go over the HLS ecosystem and the open source HLS components that help in building an accelerator. This ecosystem provides resources from IP libraries to full toolkits with real working designs.
