Description
The AT75C220, Atmel’s latest device in the family of smart internet appliance proces-
sors (SIAP), is a high-performance processor designed for professional internet
appliance applications such as the Ethernet IP phone. The AT75C220 is built around
an ARM7TDMI microcontroller core running at 40 MIPS with an OakDSPCore co-pro-
cessor running at 60 MIPS and a dual Ethernet 10/100 Mbps MAC interface.
In a typical standalone IP phone, the DSP handles the voice processing functions
(voice compression, acoustic echo cancellation, etc.) while the dual-port Ethernet
10/100 Mbps MAC interface establishes the connection to the Ethernet physical layer
(PHY) that links the network and the PC. In such an application, the power of the
ARM7TDMI allows it to run a VoIP protocol stack as well as all the system control
tasks.
Atmel provides the AT75C220 with three levels of software modules:
a special port of the Linux kernel as the proposed operating system
a comprehensive set of tunable DSP algorithms for voice processing, tailored to be
run by the DSP subsystem
a broad range of application-level software modules such as H323 telephony or
POP-3/SMTP E-mail services
