system and methods for fixed point approximations in display flow (dsc) compression

摘要

systems and methods for using fixed point techniques rather than floating point techniques are provided in order to calculate various parameters for encoding video data including target rate, qp adjustment, store completeness, a lagrangian parameter for a bit rate, and / or a lagrangian parameter for store completeness. By determining one or more parameters using the fixed point, the cost of hardware implementation can be reduced.
