Electronic coding of products and documents using RFID backed by the ubiquitous computing brings new business and secure life styles. The world smallest wireless silicon IC "mu-chip" storing a unique 128 bits ROM ID code number has been developed for a reliable automatic authentication through a network based secure ID management. Its extremely small size chip (0.4 mmtimes0.4 mm) with 50...
This paper presents a design scheme for an intelligent fieldbus master with Ethernet interface based on Profibus. Significance of the design scheme was discussed, as there are many different kinds of fieldbuses coexisting. Architecture of Profibus protocol and its state machine was investigated. According to the state machine, an integrated communication process of the master was analyzed, and a design...
Dynamic voltage scaling (DVS) is a technique used in modern microprocessors operated by battery to set voltage and frequency levels at proper values that meet performance requirements while minimizing energy consumption. Most of the present work on DVS management, however, is based on simplistic assumptions about the hardware characteristics that limit the real applicability of the proposed algorithms...
This paper presents a design scheme to implement tele-measurement through Internet. Significance of the scheme in monitoring systems is presented, and its development trend is analyzed. The design scheme consists mainly of a communication platform and a peripheral signal-sampling module. An approach to design the communication platform based on embedded microprocessor ARM and embedded operation system...
The new generations of SRAM-based FPGA (field programmable gate array) devices are the preferred choice for the implementation of reconfigurable computing platforms intended to accelerate processing in real-time systems. However, FPGA's vulnerability to hard and soft errors is a major weakness to robust configurable system design. In this paper, a novel built-in self-healing (BISH) methodology, based...
