A design method of 5B6B codec of digital optical terminal adopted very-high-speed integrated circuit hardware description language (VHDL) based on Altera development system and Quartus2 of software development is presented through the research on optical fiber transmission code mBnB in this paper, the system has strong portability, flexibility and high running speed. Finally, the feasibility and advance...
We present the software and hardware implementations of AMR codec for IMT-2000 system. The real-time implementations of AMR codec algorithm are achieved using TMS320C62xx DSP chip and Teak-Lite DSP core. We describe respectively efficient software schemes for coding AMR codec algorithm and hardware designs. The AMR codec is evaluated and confirmed in 3GPP test sequences, stand-alone test system and...
