Abstract: Techniques and systems are provided for processing video data. For example, an apparatus (e.g., a coding device, such as an encoder) can receive a residual portion of a block of a frame of the video data. The block is a first block in a row of the frame. The apparatus can receive a quantization parameter (QP) value determined for the residual portion of the block, and can determine all transform coefficients of the residual portion of the block have zero values. The transform coefficients can include quantized transform coefficients. The device can compare the received QP value determined for the residual portion of the block to a threshold QP value, and can determine a final QP value for the residual portion of the block based on whether the received QP value is greater than the threshold QP value.

Abstract: Systems and methods implemented in firmware and hardware domains may include writing by the firmware domain configuration information to a memory for a plurality of passes of hardware processing, programming by the hardware domain configuration registers with the configuration information retrieved from the memory, and processing by the hardware domain the plurality of passes in accordance with the configuration information programmed in the configuration registers. The configuration registers may be programmed after the configuration information are written to the memory.
