Error Resilience Evaluation of Approximate Storage in the Motion Compensation of VVC Decoders

This paper presents an error resilience evaluation when approximate storage is employed on the Memory of Reconstructed Frames in the Motion Compensation step of VVC decoders. An error injection framework for memory operations is defined to simulate approximate storage using a set of typical DRAM and SRAM Bit Error Rates. Moreover, the resilience of the Motion Compensation is measured considering the final visual quality of the decoded frames. Experimental results demonstrate the resilience to approximation in the context of VVC decoders' motion compensation and indicate the potential of exploiting approximate storage for the Memory of Reconstructed Frames.
