Prospector: Synthesizing Efficient Accelerators via Statistical Learning
DescriptionAccelerator design is expensive due to the effort required to understand an algorithm and optimize the design. Architects have embraced two technologies to reduce costs. High-level synthesis automatically generates hardware from code. Reconfigurable fabrics instantiate accelerators while avoiding fabrication costs for custom circuits. We further reduce design effort with statistical learning. We build an automated framework , called Prospector, that uses Bayesian techniques to optimize synthesis directives, reducing execution latency and resource usage in field-programmable gate arrays. Prospector discovers Pareto-efficient designs more quickly than prior approaches and permits new studies for heterogeneous accelerators.
