Dynamically reconfigurable architecture system for time-varying image constraints (DRASTIC) for HEVC intra encoding

We introduce the use of a dynamically reconfigurable architecture system for time-varying image constraints (DRASTIC) and consider applications in HEVC intra encoding. DRASTIC provides a framework for jointly optimizing complexity-rate-distortion for different operating modes. DRASTIC optimization involves dynamically reconfiguring parameters (e.g., the quantization parameter, encoding configuration modes) in software for achieving fine optimization control. The fine control achieved with the use of the DRASTIC modes is shown to perform significantly better than the standard use of fixed profiles.
