Very Large-Scaled Integrated (VLSI) processors and their applications to electronics systems, where VLSI processors are used as a “brain” for intelligent control like human beings, are the key components in the recent information communication technology (ICT) society. In this research division, we explore a path towards a new paradigm VLSI processor beyond brain utilizing novel device technologies and new-paradigm circuit architecture such as logic-in-memory architecture.
New Paradigm VLSI System(Prof. Hanyu)
We are studying a “new-paradigm VLSI computing” concept that investigates the optimal design through all the VLSI design layers from a device/material design level to an application-oriented algorithm level.“Logic-in-memory VLSI architecture,”where storage elements are distributed over a logic-circuit plane, makes global wires reduced greatly.To implement a logic-in-memory VLSI compactly, we utilize nonvolatile devices such as magnetic tunnel junction (MTJ) devices and focus on other challenging research subjects such as stochastic logic.
- Nonvolatile logic-in-memory VLSI architecture and its application to ultra-low-power VLSI processors
- Device-model-based new-paradigm VLSI computing architecture
- Asynchronous-control/multiple-valued data representation-based circuit for a high-performance Network-on-Chip
- Low-power VLSI design technology based on stochastic logic
New Paradigm VLSI Design (Assoc. Prof. Natsui)
We are studying a new VLSI design paradigm for highly-dependable VLSIs in the nanoscale and post-silicon era. To fully utilize the benefits of technology scaling, we are focusing on PVT-variation-aware VLSI architecture and its applications, self-adaptive system for resilient VLSI, brain-like optimization algorithm and its application to VLSI design methodology, and electronic design automation (EDA) algorithms for Nonvolatile logic-in-memory VLSI.
