Electroencephalogram (EEG) is a widely used experimental tool in psychological research. In this study, we used EEG to research the driving safety by measuring the dynamic changes of drivers' emotions in a long tunnel. Through the study whether there was a tunnel, and whether there was a large amount of traffic flow in the tunnel, we found a long tunnel only makes a slight negative effect on driver's...
A video decoding coprocessor used as H.264 main profile is presented. In the coprocessor, some decoder accelerating modules are involved, such as inter predictor, intra predictor, IDCT and weighted prediction. When the frequency of the system clock is 133MHz, the average time for this coprocessor to decode 720x480’s P frame is 9.2ms. After being synthesized by Design Compiler, 90k gates are totally...
A Programmable Gain Amplifier (PGA) used in Analog Front End (AFE) is designed to multiply the input voltage by factors of 1, 2, 4, 10, 20, 40, 100, 200 and 400V/V. The multiplication factor of the PGA can be changed via a collection of the logic bits. The PGA is designed in TSMC 0.18um 1P6M Mixed-Mode technology with a signal power supply of 1.8V and the total power dissipation is below 5mW.
