    摘要: Decoding circuitry for decoding a bitstream, the circuitry including: a processor, the processor being configured to run software for: inverse quantising quantised macroblocks to generate inverse quantised macroblocks; a streaming data connection for streaming the inverse quantised macroblocks from the processor; inverse discrete cosine transform IDCT circuitry for accepting the streamed inverse quantised macroblocks and IDCT transforming them to generate reconstructed prediction error macroblocks; and an addition circuit for adding each reconstructed prediction error macroblock and its corresponding predictor macroblock, thereby to generate a respective reconstructed macroblock.

    摘要: Very small size true directional couplers have a coupling coefficient that is independent on load VSWR. The coupler uses coupled inductors with a compensation circuit including a resistor and a capacitor, or just a capacitor. Wideband operation is suitable for many portable applications such as power detection and control for GSM, DCS-PCS, CDMA/WCDMA, Bluetooth, and WLAN systems.
