Abstract: To achieve better tradeoffs between bitrate and quality in video encoding, an improved scalar quantizer can use distortion-aware rounding offsets based on estimated distortion levels from one or more distortion contributions. A polynomial function can be used to associate distortion level to rounding offset to provide a larger range of rounding offsets. Potentially different functions can be used to define relations in segments of a range of the distortion level. Potentially different functions can be used for different scenarios (e.g., color channels, different ranges of the distortion level). In some embodiments, a group of integer errors can be used to produce more candidate rounding offsets based on the initial rounding offset. The group of candidate rounding offsets can be used to determine a group of candidate integer levels of quantized coefficient and add more flexibility to adjust the quantization error and achieve better tradeoffs between bitrate and quality.

Abstract: Methods, systems, and devices for mitigating memory die misalignment are described. A memory system may receive a command to write data to a memory device including a memory die. The memory system may determine whether the data indicated by the command (e.g., a first set of data) satisfies a threshold size. If the first set of data satisfies the threshold size, the memory system may determine whether data currently in a write buffer aligns with a boundary of the memory die. For example, depending on the data currently in the buffer, adding the first set of data to the buffer may result in die misalignment for the first set of data. To mitigate die misalignment, the memory system may pad data (e.g., add dummy data) to the write buffer, such that the padding aligns the data with the die boundary.
