Aside from performance, energy efficiency is an increasing challenge in database systems. To tackle both aspects in an integrated fashion, we pursue a hardware/software co-design approach. To fulfill the energy requirement from the hardware perspective, we utilize a low-energy processor design offering the possibility to us to place hundreds to millions of chips on a single board without any thermal restrictions. Furthermore, we address the performance requirement by the development of several database-specific instruction set extensions to customize each core, whereas each core does not have all extensions. Therefore, our hardware foundation is a low-energy processor consisting of a high number of heterogeneous cores. In this paper, we introduce our hardware setup on a system level and present several challenges for query processing. Based on these challenges, we describe two implementation concepts and a comparison between these concepts. Finally, we conclude the paper with some lessons learned and an outlook on our upcoming research directions.
