The essential guide to IT transformation

With Chipzilla and co blethering on about how wonderful Systems on a Chip will be, DeCadence's developers up in Silicon Glen have quietly got on with it and taped out the first SoC chip aimed at the burgeoning Internet telephony market. Working for French telephony outfit Aplio, which launched its standalone Voice over IP (VoIP) phone in the UK earlier this year, DeCadence's new Trio chip contains an ARM7 32-bit RISC core, and two OAK DSP cores -- practically everything needed to build standalone Internet telephony and MP3 audio appliances, set-top boxes and smart phones. The phone plugs into a normal socket and establishes a connection through the web, then rings the caller and callee back providing International calls at local rates without needing a PC. While the existing Aplio phone costs around $200, the new chip is expected to chop the cost to less than $100. ® Little known Register fact: DeCadence is the only chip design company in the world named after a Steven Berkoff play.
