SYSTEM AND METHODS FOR FIXED-POINT APPROXIMATIONS IN DISPLAY STREAM COMPRESSION (DSC)

摘要

Provided are systems and methods for used fixed-point instead of floating point techniques in order to calculate various parameters for coding video data, including target rate, QP adjustment, buffer fullness, a Lagrangian parameters for a bitrate, and/or a Lagrangian parameter for the fullness of the buffer. By determining one or more of the parameters using fixed-point, hardware implementation costs may be decreased. REFER TO FIGURE 4
