Integrated Architecture Lab
Machine-translated · View original
The lab co-designs software and hardware to build highly efficient LSI.

AboutAbout the lab
Beyond Moore's Law, embedding intelligence in circuits
The Integrated Architecture Lab studies integrated circuit technology for continuing to process information with high efficiency even after the end of Moore's Law.
Taking the approach of designing software and hardware together, the lab works on cutting-edge architecture technology and system-oriented integrated circuit technology.
Together with the Integrated Nanosystems Lab, it forms the Advanced LSI Engineering research group (LALSIE), promoting industry-academia and inter-university collaboration.
Students interested in LSI design or system design are welcome.
Key terms
- LSI
- An integrated circuit that packs many transistors onto a single chip
- Architecture
- The structural framework of a computer's design, determining which components handle which parts of a computation and how
- Edge AI
- A approach in which AI computation is performed inside a device at hand, without sending data to the cloud

ResearchResearch themes
The lab aims to go beyond the end of Moore's Law and open up computing based on new principles. By designing software and hardware together, it studies low-power inference mechanisms and the LSI architectures that run them.
*Illustrative imageEdge AI and Lightweight Inference
The lab works on binary Bayesian neural networks, stochastic in-memory computing, and privacy-preserving federated learning. It implements extremely low-power edge inference and architectures that learn on the device itself.
*Illustrative imageVLSI Architecture Design
The lab handles everything from design to chip fabrication for CNN accelerators based on coarse-grained reconfigurable architectures (CGRA) with adjustable degrees of parallelism, memory-centric neural network processors, and deep reinforcement learning engines for hardware.

Ratings and reviews reflect the experiences of individual current or former students, not the lab's official views. Whether a lab has reviews, or how many, says nothing about the lab itself.
Students who take part in an interview may receive a thank-you gift worth ¥1,000, regardless of what they say.
