Video signal Codec LSIs with on-chip CMOS image sensors for wireless communications

一种新的算法（即，多步“断裂法”技术）。新技术可以减少所需的计算量约1/50的传统的全搜索算法，而它可以保持一个平均绝对误差（MAE），covalent，一个信号噪声比（SNR），在相同的数量，全搜索算法。这种计算量的大幅减少可以将运动估计器阵列的功耗降低约100，000倍。运动估计器、SRAM、CMOS图像传感器、用于研究新的低功耗技术的TEG等已经使用0.18 μ m CMOS技术设计、制造。他们的特点将被衡量。

A new algorithm (I.e., a multi-step "breaking-off method" technique) has been developed. The new technique can reduce the amount of computation required to about 1/50 that of the conventional full-search algorithm, while it can maintain a mean absolute error (MAE), covsequently, a signal to noise ratio (SNR), at the same quantity as those of the full-search algorithm. This drastic reduction in the the amount of computation can reduce power dissipation of a motion estimator array by a factor of about 100,000.The motion estimator, SRAM, CMOS image sensors, TEGs to investigate new low-power techniques, etc. have been designed, fabricated using 0.18 um CMOS technique. Their characteristics will be measured.
