| Research Abstract |
For sensor network systems using serial communication, we developed an interruption network system which enables temporal-spatial data compression. In the system, each sensor element monitors a bus line for avoiding data collision. In addition to that, to control data transmission period, sampling time, sampling period and data transmission threshold value can increase data transmission throughput of the whole network system. We fabricated a sensor LSI using TSMC0.18um CMOS process, whose characteristics are 2.4mm2 area, 0.11ms high-speed response and 2.23mW low-power consumption at 10MHz clock operation and 1024 clock cycle sampling.
