Implementation Of H.264 Decoder On Combine Platform Of Arm And DSP

Abstract

H.264 is an emerging video coding standard, which aims at compressing high-quality video contents at low bit-rates. While the new coding and decoding processes are similar to many previous standards, the new standard includes a number of new features and thus requires much more computation than most existing standards do. The complexity of H.264 standard poses a large amount of challenges to implementing the coding scheme in real-time via software on personal computer. H.264 Decoder require high computation because of which it take very high execution time. Decoder process is introduced as a sequential process which works on a single processor but to take advantage of heterogenous environment or use of multi processor the requirement of parallelizing the decoder process can be helpful using . The main goal for Implementing H.264 decoder on combine platform is to take advantage of both processors execution power. OMAP provides combine platfoem of ARM and DSP processor with Hardware accelerator which can use execution power of two processors and can makes the performance fast.
