Popis
Shrnutí:Coarse-grain reconfigurable architectures, which provide high computing throughput, low cost, scalability, and energy efficiency, have grown in popularity in recent years. SiLago is a new VLSI design framework comprised of two coarse-grain reconfigurable fabrics: a dynamically reconfigurable resource array and a distributed memory architecture. It employs the Vesyla compiler to map streaming applications on these fabrics. Binding is a critical step in the high-level synthesis that maps operations and variables to functional units and storage elements in the design. It influences design performance metrics such as power, latency, area, etc. The current version of Vesyla does not support automatic binding, and it has to be specified manually through pragmas, which makes it less flexible. This paper proposes various approaches to automate the binding in Vesyla. We present a list scheduling-based approach to automate functional unit binding and an integer linear programming approach to automate register binding. Furthermore, we determine the binding of various basic linear algebraic subprogram and image processing tasks using the proposed approaches. Finally, a comparative analysis has been made between the automatic and manual binding concerning the power dissipation and latency for various benchmarks. The experimental results show that the proposed automatic binding consumes significantly less power for nearly the same latency as manual binding.
