ZigZag - Deep Learning Hardware Design Space Exploration

🌀 ZigZag

ZigZag is a novel HW Architecture-Mapping Design Space Exploration (DSE) framework for Deep Learning (DL) accelerators. It bridges the gap between algorithmic DL decisions and their acceleration cost on specialized hardware, providing fast and accurate HW cost estimation. Through its advanced mapping engines, ZigZag automates the discovery of optimal mappings for complex DL computations on custom architectures.
