Title: An optimization of ITU-T wideband codec G.711.1 on ARM processor
Abstract: ITU-T wideband speech codec G.711.1 extends and interoperates with widely-used narrowband G.711 codec. This results in an efficient deployment of G.711.1 codec over existing G.711-based VoIP to provide higher voice quality. However, processing capacity of commercial processors is very limited to implement wideband codec; therefore the codec needs to be optimized for real-time processing. This work focuses on optimizing C code by assembly in Basic Operators (BASOP), that shows the significant improvement of complexity and execution time of G.711.1 codec on ARM processor.
