A Survey on Reconfigurable System-on-Chips

Abstract

The requirements for high performance and low power consumption are becoming more and more inevitable when designing modern embedded systems, especially for the next generation multi-mode multimedia or communication standards. Ultra large-scale integration reconfigurable System-on-Chips (SoCs) have been proposed to achieve not only better performance and lower energy consumption but also higher flexibility and versatility in comparison with the conventional architectures. The unique characteristic of such systems is integration of many types of heterogeneous reconfigurable processing fabrics based on a Network-on-Chip. This paper analyzes and emphasizes the key research trends of the reconfigurable System-on-Chips (SoCs). Firstly, the emerging hardware architecture of SoCs is highlighted. Afterwards, the key issues of designing the reconfigurable SoCs are discussed, with the focus on the challenges when designing reconfigurable hardware fabrics and reconfigurable Network-on-Chips. Finally, some state-of-the-art reconfigurable SoCs are briefly discussed.
