Abstract :
In this paper, we describe the use of magnetic RAM (MRAM) in coarse-grained reconfigurable arrays (CGRAs) as a configuration cache to allow for bulk low-energy storage and rapid device reconfiguration. If an energy-saving configuration update for an application is needed, a new configuration can be quickly swapped into compute blocks and interconnect switchboxes to minimize system down time. The determination of when to configure and an analysis of the CGRA architectural impact of MRAM is evaluated via system-level emulation. Our experiments show that the use of MRAM reduces overall application energy consumption by nearly 30% when dynamic reconfiguration is used.
