摘要： In one example, a method of encoding video data includes allocating, based on a complexity of a reference frame and a quantity of bits allocated to a current frame, a quantity of bits to a current largest coding unit (LCU) included in the current frame. In this example, the method also includes determining, based on the quantity of bits allocated to the current LCU, a quantization parameter (QP) for the current LCU, and encoding the current LCU with the determined QP.

摘要： Techniques are described for performing transformation on video data. A transform circuit may receive M sample values of the video data from a pre-transform buffer, and process the M sample values with N computation units of the transform circuit to generate intermediate values. Processing the M sample values to generate the intermediate values includes feeding back temporary values from output of one or more of the N computation units to input of one or more of the N computation units. The transform circuit may store a first set of the intermediate values in a transpose buffer, and store a second set of the intermediate values in the pre-transform buffer that are to be later retrieved for storage in the transpose buffer.
