Abstract
Customized architecture is widely recognized as an impor- tant approach for improved performance and energy-efficiency. To balance generality and customization benefit, researchers have proposed to federate heterogeneous micro-engines. Us- ing the 10x10 architecture and an integrated image and vi- sion benchmark as a case study, we explore the performance and energy benefits achievable. Results for current 32nm technology and DDR3 memory show 10x10 architecture ben- efits of 140x performance and 72x energy overall. Adding 3D-stacked DRAM increase benefits to 171x (performance) and 100x (energy). Finally, considering future 7nm tran- sistor process, benefits as large as 597x (performance) and 137x energy are observed.
