摘要： A motion estimator, employing a three-step hierarchical search block-matching algorithm for obtaining a motion vector by block-matching between a current block and its corresponding block, is provided. The motion estimator comprises: a memory block, a matching unit and a control unit. The memory block is for storing a candidate block corresponding to the current block. The matching unit matches the size of a current block with aforementioned candidate block and sub-candidate blocks identical to the current block. The control unit supplies candidate blocks in the memory blocks to the matching unit according to a prescribed matching sequence, and writes the candidate block corresponding to the current block to the section no longer used in the memory block simultaneous to the performance of Step 3 of a three-step hierarchical search block-matching algorithm.

摘要： A dual-slope analog-to-digital converter and a comparison circuit for the dual-slope analog-to-digital converter. The dual-slope analog-to-digital converter includes a buffer, an integrator coupled to the buffer and the comparison circuit. The comparison circuit includes a differential output comparator and a comparison unit. The differential output comparator is coupled to the integrator and produces a pair of differential signals to output. The comparison unit receives the differential signals and chooses a signal, whose voltage is from a first level to a second level, from the differential signals to produce an output signal.
