A Memory Bandwidth-efficient Architecture for Lossless Compression Using Multiple DPCM Golomb-rice Algorithm

In this paper, we propose a lossless compression architecture with less memory bandwidth. For this purpose, the compression ratio is improved with the prediction function using multiple differential pulse-code modulation algorithm which performs the variable sign code Golomb-rice encoding algorithm with entropy coding. For performance evaluation, several experiments were performed on 4k image sequences on the proposed architecture. The results show that it achieved an average compression ratio of 1.67 on the benchmarks.
