Research theme: Low-Power, High-Performance, and Dependable Computing
We are working on the realization of high-performance, low-power, and dependable computing systems and networks.
- Low-Power and High-Performance Computer Systems
A lot of socially important applications require high-performance computing ability. However, the power consumption of high-performance computing systems should be low because it is hard to cool such systems. To overcome this problem, we are working on a low-power and high-performance computing systems based on dynamic run-time cooperation of computer architecture and system software.
- Low-Power System LSIs
System LSIs are required to execute wide range of applications. One of the liming factors of performance improvement of those LSIs is power, and thereby, dramatic reduction of power consumption including dynamic power and leakage power becomes a key challenge. We are trying to solve this problem by using the circuit-level and architecture level cooperative fine-grain power management.
- Dependable Computing Systems
It is inevitable that faults will arise from components (either software or hardware) that constitute a computer system. Therefore, the property of fault tolerance, which is the ability of a system to work propoerly despite its faulty components, is very important. In order to establish the methodology of designing fault tolerant systems, we are working on fault models at various levels of system design, system reconfiguration and recovery, and decentralization of redundancy.
