In view of the current stringent need to the real-time compression algorithm of the high-speed and high-resolution image  such as remote sensing or medical image and so on  in this paper  No List SPIHT (NLS) algorithm has been improved  and a fast parallel SPIHT algorithm is proposed  which is suitable to implement with FPGA. It can deal with all bit-planes simultaneously  and process in the speed of 4pixels/period  so the encoding time is only relative to the image resolution. The experimental results show that  the processing capacity can achieve 200MPixels/s  when the input clock is 50MHz  the system of this paper need 2.29ms to complete lossless compression of a 512x512x8bit image  and only requires 1.31ms in the optimal state. The improved algorithm keeps the high SNR unchanged  increases the speed greatly and reduces the size of the needed storage space. It can implement lossless or lossy compression  and the compression ratio can be controlled. It could be widely used in the field of the high-speed and high-resolution image compression. 2010 IEEE.

We investigated electro-optic modulator structures to target low drive voltage  high-speed modulation  and small device size with c-axis grown BaTiO3/MgO ferro-electric thin films. In this study  the calculations are focused on the ideal thin film with a quadratic relation between the half-wave drive voltage V and the interaction length L in the electro-optic modulation case we obtained in previous work. With the quadratic electro-optic modulating relation and the optimal rib waveguide structure of BaTiO3/MgO thin films  the frequency-voltage-size performances for 2.5GHz  10GHz  40GHz  and 100GHz modulation bandwidths have been obtained under half-wave drive voltages of 0.8V  1.6V  3.0V and 4.8V  respectively  for the ideal film with r51=730 pm/V at 1550nm wavelength  where both the phase velocity matching condition and the conductor induced microwave attenuation are considered. The required device lengths to achieve these four typical values of modulation bandwidth are 3.3 mm  0.8 mm  0.4 mm and 0.2 mm  respectively. With the c-axis grown BaTiO3/MgO crystal thin films and the quadratic electro-optic modulating relation  an electro-optic coefficient of reff=180 pm/V for the c-axis grown BaTiO3/MgO ferro-electric thin films was measured  which is relatively far from the ideal value of r51=560 pm/V. copyright The Electrochemical Society.
