Coarse-grained reconfigurable architectures (CGRAs) is one of the suitable devices for IoT (Internet of Things) and edge-computing because of their high energy efficiency and programmability. The CGRAs process a compute-intensive part of an application program (especially a loop part) more efficiently than general purpose processors. CMA (Cool Mega Array) is an energy-conscious CGRA with a task-level reconfiguration instead of a cycle-level one. However, the CMA faces some limitations related to data management because of the aggressive pursuit of power saving. In this paper, we introduce a new CMA architecture VPCMA2 to relax the constraints and to improve energy efficiency. Then, we implement it with a 65-nm process technology to evaluate a hardware overhead due to the improvement. According to the evaluation results, the new design does not influence its maximum operating frequency. Although new functionalities brought about 17% power overhead and 10% area overhead, a remarkable improvement of application mappability and data handling was achieved.
