| Research Abstract |
This work investigated the reconstruction of the software of an operating system (OS) kernel in order to enable the utilization of many core processors and SIMD units inside the kernel. It is required for the existing OS kernels to maintain their execution environment by themselves, and such a restriction forced the use of specific programming languages and became the barrier to utilize the parallel processing functions of processors. This work constructed the base execution environment that improves the flexibility of the OS kernel implementation. Upon the constructed base execution environment, the researches to utilize more parallel processing features inside the OS kernel were conducted.
