| Research Abstract |
The purpose of this study is to develop system software such as the following :
1) Development of a system soflware with flexibility, and
2) Gaining high performance for multimedia applications.
(1) Development of a system software with flexibility
1) Development of a reconfigurable operating system
We designed a framework of an operating system that dynamically changes its structure to adapt multimedia applications and developed its ototype. In addition, we showed that it effectively works.
2) Development of the PPL user-level thread library
We designed and developed a user-level thread library, called PPL.PPL allows multimedia applications to be effectively executed.
(2) Processor scheduling for large-scale systems
We proposed a processor scheduling scheme that combines together with memory management for large-scale systems. The scheme allows multimedia applications to be efficiently executed.
(3) Auto-parallelizing compiler for large-scale systems
We proposed a new program and data partitioning algorithm for large-scale systems. In addition, we showed the effectiveness of the algorithm.
