Abstract (in Japanese) (See Japanese page) 
(in English) With the recent advances in semiconductor technology, many transistors have been integrated into a single chip and Chip-Multiprocessors (CMPs) are common today. However, the number of cores in them has been increasing and it is difficult to support them with the traditional common bus. To solve this problem, Net-work-on-Chips (NoCs) have been researched in recent years. The load sharing by routing can reduce the transfer delay of packets and improve the performance of NoCs.
However, this technique faces the limitation on constraints of the mounting area of routers.
In this paper, we add a priority to a packet header of NoCs. We implemented
an on-chip router with a function of priority-based packet overtaking. In addition, we implemented the mechanism to prevent resource occupation caused by priority control.
Evaluation results show that the effectiveness of the priority-based packet overtaking. They also show that transfer latency of low-priority packets can be reduced while maintaining that of high-priority packets by resource control.
