Acceleration of Audio Video coding Standard (AVS) Jizhun profile decoder has been proposed for ARM Cortex-A with NEON. Data level parallelism is utilized to effectively use the SIMD capability of NEON. Key modules are redesigned to make them SIMD friendly. Our optimized C implementation is set as start point for the acceleration. Thanks to effective use of ARM Cortex-Ax architecture and NEON SIMD engine, AVS decoding has been accelerated considerably. Results are provided for the overall acceleration in decoding and individual acceleration for key modules of AVS decoder.
