Cool Mega-Array (CMA) is an energy-efficient reconfigurable accelerator for battery-driven mobile devices. It has a large processing-element array without memory elements for mapping an application's data-flow graph, a simple programmable microcontroller for data management, and data memory. Unlike coarse-grained dynamically reconfigurable processors, CMA reduces power consumption by switching hardware context and storing intermediate data in registers.
