“…In this dictionary, R 0 is used to explore the first sort of spatial locality while the other reference items are responsible for the second sort of spatial locality. In addition, we also propose a similar fine-grained dictionary scheme as in [10] by building specialized dictionary for each pixel component of R, G and B rather than the whole pixel so as to achieve an even better performance.…”

“…The algorithm is derived from the classic LZ77 algorithm with a dictionary containing several previous pixels as reference items. Yang et al [10] improved the algorithm by modifying the content of the dictionary. They also construct specific dictionary for every pixel component rather than the whole pixel to improve performance.…”

“…Spatial locality in frame images is proved by many studies and can be classified into two categories [10]. First, a pixel may share exactly the same value with its adjacent pixels.…”

Display controller processes a great amount of data within a bounded time and thus requires high memory bandwidth. The memory bandwidth will dominate system performance, especially in embedded systems. In this paper, we propose a hybrid algorithm called APE (Adaptive Pixel Encoding) for lossless frame buffer compression considering high compression performance and real time operation. The algorithm combines dictionary coding and run length coding to achieve a low compression ratio. We integrate APE frame buffer compression architecture into a display controller. Experimental results show that the proposed algorithm gains 19.7% of compression ratio and 66.2% of memory bandwidth reduction ratio during sweep operation. It is much more effective than all previous works.

High definition (HD) video decoder processes a great amount of data within a bounded time and thus requires high memory bandwidth. The memory bandwidth will dominate system performance, especially in embedded systems. In this paper, we propose a lossless hybrid display frame compression algorithm called HPE (Hybrid Pixel Encoding) for HD video decoder considering high compression performance and real time operation. The algorithm combines dictionary coding and run length coding to achieve a low compression ratio. We integrate the proposed design into an H.264 decoder. Experimental results show that the proposed algorithm gains 67.7% of data reduction ratio on average when decoding 1080-HD video. It is much more effective than all previous works.
