With the increasing power density of deep submicron technology, temperature becomes one of the dominating factors for the reliability of integrated circuits. Coarse-grained reconfigurable devices typically exhibit spatially nonuniform activity, which results in areas of localized heating, so called hot spots. In this work we investigate the effects of continuous activity migration in order to prevent...
Multi-context reconfigurable arrays provide the ability for fast dynamic reconfiguration once the configurations have been stored into the architecture's context memory. Besides switching the context of the entire array it is also possible to reconfigure contexts from outside the array, which we call external reconfiguration. If supported by the architecture, this reconfiguration, as well as switching...
In the last years, aside from fine-grained reconfigurable architectures such as FPGAs, coarse-grained reconfigurable architectures (CGRAs), which typically have building blocks of a fixed bit-width (8 bit, 16 bit, etc.), have gained in importance in academia as well as in industry. CGRAs are usually used for domain-specific computations and have advantages over traditional FPGAs in terms of area and...
It is well known that the area efficiency of a digital circuit can be improved by reconfiguration due to the reuse of resources. In this paper, we show that this benefit can be achieved for a wide range of applications if the reconfiguration can take place within each clock cycle, and we quantify the benefit by area estimations from a synthesizable architecture model. Although reconfiguration typically...
