A research division that designs next-generation computer systems.

AboutAbout the lab
Thinking about next-generation computers from the design stage
The AI Computing Research Division is a division of the System LSI Research Center, and Professor Koji Inoue serves as its head.
Professor Inoue studies computer system architecture as a foundational technology supporting the next-generation information society.
The research targets computer systems that can adjust the balance among performance, energy consumption, safety, and reliability according to the usage environment and situation.
The lab does not stop at simulation; it also carries out actual VLSI design.
The center is an organization that makes use of Kyushu University's research faculty system, and its members remain affiliated with their existing research faculties while carrying out research at the center.
Key terms
- Computer system architecture
- The basic ideas behind the internal structure and design of a computer.
- VLSI
- Very-large-scale integration: a large-scale integrated circuit that puts a very large number of elements on a single chip.
- Superconducting single flux quantum (SFQ) logic
- A type of logic circuit that uses superconducting circuits and operates at an extremely low temperature of 4.2 kelvin.
ResearchResearch themes
Division head Professor Koji Inoue and Associate Professor Satoshi Kawakami list next-generation computer system architecture as their research theme. Professor Inoue takes safety and reliability into account in addition to performance and energy consumption, and also works on VLSI design.
