Internet of Things (loT) is network connected “Things” such as vehicles, buildings, embedded systems, sensors, as well as people. IoT enables these objects to collect and exchange data of interest to complete various tasks including patient health monitoring, environmental monitoring, system condition prognostics and prediction, smart grid, smart buildings, smart cities, and do on. Due to the large...
This paper introduces the principle of frequency divider and circuit design based on VHDL??Cwhich describes integer and half-integer frequency division and the decimal frequency division algorithms. It can achieve any number divider for base frequency. The generality of this design is good. It can be used into the design of diverse digital circuit systems.
The design adopts EDA technology to achieve a remote data acquisition system. The system aims at the lack of data acquisition card which is high cost and easily be affected within PC environment, thus it uses Universal Serial Bus technology to collect the data. FPGA is adopted as the controller to control A/D converter and store and deal with the converted data, the data is transmitted to the computer...
To address the issues of single event upsets caused by radiation in outer space to micro-satellites, we proposed a novel reconfigurable on-board computer system with three soft core CPUs inside the Field Programmable Gate Array(FPGA), with the function of error detecting and restoring configuration. Two of the soft core CPUs act as the central processing unit, doing housekeeping of the satellite;...
HMMer is a widely-used bioinformatics software package that uses profile HMMs (Hidden Markov Models) to model the primary structure consensus of a family of protein or nucleic acid sequences. However, with the rapid growth of both sequence and model databases, it is more and more time-consuming to run HMMer on traditional computer architecture. In this paper, the computation kernel of HMMer, P7Viterbi,...
A new architecture of UHF (ultra high frequency) RFID (radio frequency identification) digital receiver for SoC (system-on-chip) implementation is presented in this paper. For the system requirements, the design uses a unique two-stage correlation algorithm to estimate the frequency of the received data which may have large frequency deviation and also to achieve fast data decoding. Considering the...
A high performance digital demodulator for RFID reader receiver is proposed. After carefully analyzing the characteristics of the received data, correlation operation is introduced into the demodulator to estimate the frequency of the received data and decode them. Simulation result indicates that this demodulator can work well under the 6dB input signal-to-noise ratio (SNR) with +/- 22% frequency...
