This book provides a meaningful review of state-of-the-art reconfigurable logic systems, spanning a broad range of expertise from architectures, tools, and applications to emerging technologies.Field Programmable Gate Arrays are one of the most famous architectural families of reconfigurable devices. Historically, reconfigurable logic and FPGAs were categorized together; now the shift in traditional computation systems is towards large arrays of fine-grain simple processors and low-level software control in high-performance circuits, such as Graphical Processor Units (GPU) or Multi-Processor System-on-Chips (MPSoCs).
