Abstract

This paper presents CREMA, a coarse-grain reconfigurable array with mapping adaptiveness. Mapping adaptiveness consists of tailoring the array to a specific application requirements. Run-time reconfigurability allows the re-usage of same PE with different functionality and interconnections among the ones supported. We proved this approach very efficient if compared with a standard CGRA. In our test cases CREMA gets a performance speed-up from 1.5X to 4X, reducing in the same time the area occupation by 80%-90% in comparison with butter CGRA.
