Abstract (in Japanese) (See Japanese page) 
(in English) For wireless nensor nodes, it is important to reduse power consumption while completing tasks within their deadline. We are developing a multi-core CPU can reduce power consumption enabling users to easily manage hard real-time tasks. This paper presents initial experiment about power consumption of a multi-core CPU we are developing. We run the benchmarks on the prototyped multi-CPU sensor node and measure its power consumption with changing a number of CPUs. The results show a sensor node with triple CPUs can eliminate about 70 % of power consumption compared to a single CPU sensor node.
