Data-Driven Networking
Architecture Laboratory
データ駆動ネットワーキングアーキテクチャ研究室
Processing is passively initiated upon the arrival of data.
We study networking architecture based on data-driven (non-von Neumann)
processors, from networking schemes to circuit implementation.
What Makes Us Unique
Unique Data-Driven Processors
We study non-von Neumann processors in which operations become executable as soon as their operands arrive — realizing real-time multiprocessing without context-switching overheads.
From Networks to Circuits
Our research straddles multiple fields: networking schemes, processor architecture, and circuit implementation. You can experience the design of a whole system, with patents granted and pending.
Small Lab, Close Mentoring
A small group means easy access to your adviser and an environment where you can focus on research, together with cross-sectoral seminars through the SSH Alliance with three partner laboratories.

Research Highlight
Networking Architecture Based on Data-Driven Processors
We pursue data-driven processors inherently suitable for networking processing — guaranteeing real-time constraints even as traffic increases — working consistently from processing-scheme design to circuit implementation and evaluation on FPGAs, and publishing the results both domestically and internationally.
