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.

Data-driven processor Bursty arrivals Guaranteed throughput matching the input rate
Because each stream is processed independently, its throughput (= 1 / output interval of result data) naturally keeps up with its input rate (= 1 / arrival interval of data) — conceptual image of the Stream-Thru processing scheme
