A survey on embedded reconfigurable architectures

Abstract

Application specific integrated circuits are used to provide real-time performance of handheld devices within the compact physical size and low energy dissipation. However, these circuits are inflexible for any modification like redesign and refabrication. Reconfigurable architectures are promising alternative for conventional computing devices such as application-specific integrated circuits. It provides high-level flexibility to adapt the applications through dynamic hardware customization even after fabrication. A reconfigurable computing system design considers the peculiarities of the targeted application domain along with architectural issues like dynamic reconfiguration, partial reconfiguration, hardware/software co-design and context management. A brief survey has been carried out to understand the concepts and applications of CGRA, FPGA, SoC, NoC, MPSoC, dynamic partial reconfiguration, hardware/software co-design, design-space exploration, multi-objective optimization, genetic algorithm and reconfigurable computing on wireless communications. This paper deals with the survey on modeling, design, implementation and evaluation of coarse-grained dynamically reconfigurable processor architectures targeting the real-time embedded computing domain.
