☆ Networking Architecture Based on Data-Driven Processors

A data-driven (non-von Neumann) processor is the realization of a data-driven execution model in which operations become executable after all of their operands arrive. It realizes multiprocessing without overheads such as context-switching, and thus guarantees real-time processing even when multiplicity (e.g., the number of IP packets processed simultaneously) increases, as long as the processing load stays under the design target.

This real-time multiprocessing feature is indispensable for networking, where real-time constraints are strictly demanded even as traffic increases — the data-driven processor is inherently suitable for networking processing. Based on it, we study networking architecture straddling networking schemes, processor architecture, and circuit implementation.

Life in Our Lab

Equipment

You can use the latest workstations and storage systems installed for FPGA design tools. Every student has a personal work space and an up-to-date PC.

Research Activity

You have the chance to research an extremely unique processor and gain experience in the creation, design, verification, and evaluation of a whole system — from networking schemes to circuit implementation.

Encouragement

You can publish the results of your research at domestic and international conferences. One doctoral-course member of our lab runs a company — don't miss your chance to get in touch.

Merits for Your Job Hunting

You can participate in joint R&D with domestic manufacturers and experience the process from system specification to implementation, gaining system-design skills and business experience with partner companies.
