Y U V Reusable DCT Architecture for Parallel Processing of Y U and V Transforms in HEVC

摘要

The present invention relates to a reuse decomposition architecture for parallel processing of Y, U, and V transforms in HVC, and includes YU, U for a TU (Transform Unit) consisting of luma component Y, chrominance component U and V of HEVC V residual blocks in a transpose memory, wherein the transpose memory is configured to remove 1D transformed Y, U, and V residuals for a TU of size 16x1. 1 color, and the Y, U, and V residuals of 8 x 8 TU are stored as the second color. The present invention can efficiently use a transpose memory that is not used for calculating the U and V residual transforms in parallel with the Y residual transform, A significant number of cycles are saved because the U and V residual transforms are performed during the time required to calculate the Y transform.
