ITU-T G729A Voice Codec Hardware Accelerator

The growth in wireless communication systems, cellular mobile radio and VoIP technology has created the imperative need for bandwidth efficient, high speed quality voice coding algorithms. The ITU-T G.729 CS-ACELP is a high speech quality, low-bit rate (8kbps) codec that has been proposed to meet the voice compression requirements of a modern communication system.

However the real time SW implementation of a multi-channel ITU-T G.729 compliant voice codec in conventional DSP processors is prohibitive due to the intensive amount of signal processing power required by the algorithm. To overcome this limitation Noesis Technologies has developed a revolutionized, highly efficient hybrid architecture that implements real time multi-channel G729A voice coding and exhibits the best performance-silicon area ratio available in the industry. The ntG729 IP Core can be used as a coprocessor to any processor type and can save significant computing resources for the main processor by efficiently executing the computationally intensive speech coding G729A algorithmic operations.
