Description
The Atmel AT75C310 Smart Internet Appliance Processor (SIAP) is a high-performance processor specially designed for Internet appliance applications, such as Internet telephony (Voice over Internet Protocol – VoIP). The AT75C310 is built around an ARM7TDMI microcontroller core running at 20 MIPS with two DSP co-processors running at 40 MIPS each – all three processors delivering unmatched performance for low power consumption. In a typical standalone VoIP phone, one DSP handles the voice-processing functions (voice compression, acoustic echo cancellation, etc.), while the other one deals with the telephony functions (dialing...
