Optimization of Audio and Video Encoder on ARM Platform
面向ARM平台的音视频编码优化研究

ARM is appropriate for audio and video encoder. In audio encoding, ARM supports digital signal processing,and thus can finish one DSP operation in one cycle. In video encoding, the running time can be reduced rapidly by making full use of 16 registers and using shift operation along with other operation in one instruction. Experiment proves that ARM can dramatically improve performance of audio and video encoder.
