Coarse-grained reconfigurable architectures (CGRA) employ square or rectangular arrays composed of many computational resources for high performance. Though these array fabrics are mostly suitable for embedded sys-tems including multimedia applications, they occupy large area and consume much power. Therefore, reducing area and power of CGRA is necessary for the reconfigurable architectures to be used as a competitive IP core in embed-ded systems. In this paper, we propose a new array fabric for designing CGRA to reduce area and power consump-tion without any performance degradation. This cost-effective approach is able to reduce the array size through efficient arrangement of array components and their inter-connections. Experimental results show that for multimedia applications, the proposed array fabric reduces area up to 40.32% and saves power by up to 28.35 % when compared with the existing CGRA architecture.
