This book presents a new FPGA architecture known as tree-based FPGA architecture, due to its hierarchical nature. This type of architecture has been relatively unexplored despite their better performance and predictable routing behavior, as compared to mesh-based FPGA architectures. In this book, we explore and optimize the tree-based architecture and we evaluate it by comparing it to equivalent mesh-based FPGA architectures.

This standalone reference surveys and compares mesh- and tree-based FPGA architectures. Comparing them via an exhaustive set of criteria, it displays the advantages of the tree-based hierarchical model, still largely unexplored despite its better performance.
