The purpose of this study is to develop system software such as the following :1) Development of a system soflware with flexibility, and2) Gaining high performance for multimedia applications.(1) Development of a system software with flexibility1) Development of a reconfigurable operating systemWe 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 libraryWe designed and developed a user-level thread library, called PPL.PPL allows multimedia applications to be effectively executed.(2) Processor scheduling for large-scale systemsWe 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 systemsWe proposed a new program and data partitioning algorithm for large-scale systems. In addition, we showed the effectiveness of the algorithm.

本研究的目的是开发如下系统软件：1）开发具有灵活性的系统软件，2）获得高性能的多媒体应用程序。(1)1）可重构操作系统的开发我们设计了一个可动态改变其结构以适应多媒体应用的操作系统框架，并开发了它的原型。2）PPL用户级线程库的开发我们设计并开发了一个用户级线程库PPL，PPL可以有效地执行多媒体应用程序。(2)大规模系统的处理器调度提出了一种结合内存管理的大规模系统处理器调度方案。该方案允许有效地执行多媒体应用。(3)大规模系统的自动并行化编译器提出了一种新的大规模系统的程序和数据划分算法。此外，还验证了算法的有效性。
