Abstract: A digital audio data output device having first and second post-processors that process received digital audio data in parallel. Each processor includes a mixer unit that processes received digital audio data on the fly in response to a channel mode control signal, and a volume control unit that adjusts volume level of output of the mixer unit on the fly in response to a volume level control signal. Each mixer unit includes first and second buffers that can respectively store first and second channel data, a calculator that calculates mix data from the outputs of the buffers, a third buffer that stores the mix data, and an output unit. The output unit selects and outputs one of the received digital audio data, the output of the first buffer, the output of the second buffer, the mix data, and output of the third buffer, as the output of the mixer unit.

Abstract: The present invention provides a novel biphenyl compound or pharmaceutically acceptable salts thereof, methods for preparing the same, and pharmaceutical compositions for preventing or treating diabetic complications containing the same as an active ingredient. Novel biphenyl compounds, according to the present invention, effectively suppress generation activity of advanced glycation end products, which cause diabetic complications and are a criterion for evaluating the effectiveness of a treating agent for diabetic complications, and show an excellent therapeutic effect on retina blood vessels, increased occludin, and decreased angiogenic growth factor in actual diabetic retinopathy induced retina. Thus, novel biphenyl compounds according to the present invention can be used effectively as an active ingredient in compositions for preventing or treating diabetic complications such as diabetic retinopathy.

Abstract: A method and apparatus for controlling the timing of a state transition of a serial data line (SDA) in an I2C controller are provided. The apparatus includes a processor, a serial clock line (SCL) edge detector, a counter, and an SDA generator. The processor controls an I2C controller. The SCL edge detector detects an edge of a clock signal of an SCL. The counter counts a hold time of the state transition of the SDA if a falling edge of the clock signal of the SCL is detected by the SCL edge detector. The SDA generator transits the state of the SDA if the count of the hold time is finished. Therefore, a malfunction in an I2C communication can be prevented without using a compensation circuit requiring a lot of time and cost.
