    Abstract: The present disclosure relates to a pulse radar device comprising a memory that includes a first memory and a second memory, each storing a scan vector. The device also includes a clock generator that produces a transmission clock signal and a reception clock signal. The reception clock signal is generated by delaying the transmission clock signal by a clock delay value. Furthermore, the device includes a transmitter that generates a transmission pulse by accepting the transmission clock signal from the clock generator and emits the pulse. Additionally, the device includes a receiver that receives an echo pulse reflected from a target by accepting the reception clock signal from the clock generator. The receiver then calculates the received echo pulse to generate a representative scan vector.

    Abstract: A high-speed motion estimation method for estimating a motion of a picture at high speed in a high-speed motion estimation apparatus including an integer-times motion estimation unit and a decimal-times motion estimation unit. The integer-times motion estimation unit (1) receives pixel data of a picture for estimation of motion from an external frame memory, (2) stores pixel data of a current region in a current macroblock storage where multiple inputs/outputs are made, (3) stores pixel data of an estimation region in an estimation region macroblock storage of a sharable multiple input/output bank type, and (4) predicts an integer-times motion vector using both stored pixel data. The decimal-times motion estimation unit reads the pixel data of the estimation region from the estimation region macroblock storage which is sharable, and predicts a decimal-times motion vector using the read pixel data of the estimation region and the integer-times motion vector.

    Abstract: The present invention provides a fast prediction mode determination method of a video encoder that may remove an unnecessary operation of an encoder by selectively terminating early or omitting a splitting process and a pruning process based on a probability distribution of rate-distortion values, and thereby enables the encoder to quickly determine a prediction mode. The present invention may include a method that may adaptively change a termination and omission determination criterion of the splitting process and the pruning process based on a characteristic of an input image. When using the method provided by the present invention, reliability regarding the termination and omission determination of the splitting process and the pruning process may be set and thus, it is possible to adjust the tradeoff between a decrease in an operation amount and a quality degradation of the encoder.
