Software Defined Hardware (SDH) is emerging as a transformative approach for designing reconfigurable embedded systems that can adapt dynamically to varying computational and functional requirements. Unlike traditional fixed hardware systems, SDH leverages software control to define the behavior of underlying hardware, providing flexibility, reduced design costs, and improved system efficiency. This paper presents a comprehensive review of SDH, its architecture, reconfiguration techniques, applications in embedded systems, and challenges. We highlight the state-of-the-art implementations in SDH and discuss potential future directions, including integration with edge computing and AI-driven adaptive systems. The study concludes that SDH is a promising paradigm that bridges the gap between software flexibility and hardware performance in embedded applications.
