Abstract Integrating Floorplanning In Data-Transfer Based High-Level Synthesis

Modern digital systems move and process vast amounts of data. Designing good ASIC architectures for these systems requires e cient data routing and storage. A high-level synthesis (HLS) system must consider spatial aspects of the architecture it synthesizes to achieve this. In this paper, we discuss using oorplanning information in the main HLS ow. Our HLS system, Midas, incorporates oorplanning and formulates HLS using a data-transfer model. Midas synthesizes an architecture whose data storage and transfer subsystems are spatially integrated with its execution unit. Midas also generates a high-level oorplan for the architecture, which contains the shapes and coordinates of its components and routing channel speci cations for its buses. Our experiments comparing Midas's architectures to those generated by a HLS system that does not use the data-transfer model or oorplanning show that Midas's architectures are smaller and yet allow for large amounts of simultaneous data motion and storage.
