The RecoBlock SoC platform: A flexible array of reusable run-time-reconfigurable IP-blocks

Abstract:

Run-time reconflgurable (RTR) FPGAs combine the flexibility of software with the high efficiency of hardware. Still, their potential cannot be fully exploited due to increased complexity of the design process. Consequently, to enable an efficient design flow, we devise a set of prerequisites to increase the flexibility and reusability of current FPGA-based RTR architectures. We apply these principles to design and implement the RecoBlock SoC platform, which main characterization is (1) a RTR plug-and-play IP-Core whose functionality is configured at run-time; (2) flexible inter-block communication configured via software, and (3) built-in buffers to support data-driven streams and inter-process communications. We illustrate the potential of our platform by a tutorial case study using an adaptive streaming application to investigate different combinations of reconflgurable arrays and schedules. The experiments underline the benefits of the platform and shows resource utilization. © 2013 EDAA.
