Conference paper (peer-reviewed)abstract
- A flexible and high performance SoC is developed for networked media applications by integrating two RISC cores, Ethernet network interface and coarse-grained configurable video decoding unit. Real-time 1280x720@25fps MPEG-2/MPEG-4/RealVideo decoding is achieved for on-line video streams. The SoC is fabricated in 0.13um single-poly eight-metal CMOS technology with core size of 6.4mm * 6.4mm. To achieve low power design, flexible power management strategy is implemented for dynamically control of computational capabilities with various workloads. The maximum power consumption is 414mW at 1.2V supply voltage with the corresponding system frequency of 216MHz, when real-time HD (1280x720@25fps) video streams are decoded. When the SoC decodes real-time CIF (352x288@25fps) video streams, it requires 27MHz system frequency and consumes 95mW.

Global Fresh Food Tracking Service Enabled by Wide Area Wireless Sensor Network

In: 2010 IEEE Sensors Applications Symposium, SAS 2010. - : IEEE Sensors Council. ; , s. 6-9
-
Conference paper (peer-reviewed)abstract
- A global fresh food tracking service is presented, in which a set of primary environmental conditions for transport of fresh fruits and vegetables, including global position, temperature, relative humidity, concentrations of CO2, O2 and ethylene gases and 3-axis acceleration, is collected through mobile and remotely controllable wireless sensor nodes. Real time monitoring, tracking, alarming, close-loop controlling and information sharing could therefore be provided as WEB services with service oriented architecture. Fully functioned hardware modules, protocols and system software have been developed. A 50-day field test has been successfully carried out, proving the system concept and the robustness of hardware and software designed. Due to its worldwide deploy-ability and added-values to fresh food supply chain, it is feasible to establish a practical fresh food tracking service business.
