Cool Mega Array (CMA) is an energy efficient reconfigurable accelerator consisting of a large PE array with combinatorial circuits and a small microcontroller. In order to enhance the energy efficiency of the total system, a coprocessor design of CMA(Cool Mega Array), called CMA-Geyser is proposed. By replacing the programmable microcontroller by the host processor Geyser with a dedicated hardware...
Cool Mega Array (CMA) is an energy efficient Coarse Grained Reconfigurable processor Array (CGRA) consisting of a large PE (Processing Element) array. In order to reduce the power for storing intermediate results and clock tree, the PE array is consisting of combinatorial circuits. A hardware completion detection mechanism for CMA is proposed, implemented and evaluated. Each PE uses serially connected...
A design, implementation and evaluation of low power accelerator CMA-2 were introduced. Evaluation result with real chip shows that the maximum energy efficiency is 233.7 MOPS/mW.
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...
