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, line echo cancellation, callerID detection, high-speed modem, etc. . In such an application, the power of the ARM7TDMI allows it to run the VoIP protocol stack as well as all the system control tasks. Atmel provides the AT75C310 with three levels of software modules • a special port of the kernel as the proposed operating system; • a comprehensive set of tunable DSP algorithms for modems and voice processing, specially tailored to be run by the DSP subsystems; • a broad range of application level software modules such as H323 telephony or POP-3/SMTP mail services.
