Abstract—This paper describes a multi-grain parallel accelerate system for H.264 encoder on UltraSPARC T2 processor. This system integrates pipeline parallelism, frame-level, slice-level, macroblock-level data parallelism and SIMD technology.We use x264, an H.264 video encoder to implement our parallel accelerate system. Our implementation of parallel accelerate system achieves speedup between 10.1x and 11.5x and only causes 1.04x bit rate increase on UltraSPARC T2 processor.

Index Terms—parallel video coding, H.264, SIMD, speedup
