μ-Genie: A Framework for Memory-Aware Spatial Processor Architecture Co-Design Exploration

Spatial processor architectures are essential to meet the increasing demand in performance and energy efficiency of both embedded and high performance computing systems. Due to the growing performance gap between memories and processors, the memory system of ten determines the overall performance and power consumption in silicon. The interdependency between memory system and spatial processor architectures suggests that they should be co-designed. For the same reason, state-of-The-Art design methodologies for processor architectures are ineffective for spatial processor architectures because they do not include the memory system. In this paper, we present μ-Genie: An automated framework for co-design-space exploration of spatial processor architecture and the memory system, starting from an application description in a high-level programming language. In addition, we propose a spatial processor architecture template that can be configured at design-Time for optimal hardware implementation. To demonstrate the effectiveness of our approach, we show a case study of co-designing a spatial processor using different memory technologies
