SiTel Semiconductor, working in collaboration with Target Compiler Technologies, has developed a customised audio DSP for its SC14452 Green VoIP processor. The DSP combines extreme energy efficiency with high processing performance, enabling industry-leading audio quality and power consumption. The DSPs were developed using Target’s IP Designer retargetable tool suite.
The tools allowed SiTel to develop application-specific Gen2DSPs including a C-compiler, which means customers can programme the DSPs themselves. The DSPs operate at low frequency to minimise energy consumption, yet provide high processing power. The SC14552 features two of these DSPs, which together deliver 160 MIPS. At the same time, they help minimise power consumption, enabling in-call power figures below 600 mW.
The SC14452 can support four concurrent IP connections, independent of the codec chosen. Currently supported codecs include G.711, G.729, G.722, G.726, iLBC and MP3. Highly integrated, this VoIP solution reduces the overall system bill of materials (BoM) for enterprise VoIP desktop phones and IP-DECT base stations. It features integrated DECT, CAT-iq, DECT 6.0 and KDECT support and a dedicated cryptography engine for complete call confidentially.
“SiTel strives to create state-of-the-art chipsets for the cordless telephony and VoIP markets that deliver outstanding audio quality and performance while minimizing environmental impact,” said Mark De Clercq, Product Marketing Manager at SiTel. “The Target tools have helped SiTel achieve this goal by enabling us to develop audio-specific DSPs that deliver lots of processing power while operating at low frequency.”
