UG_1x22_057 1 1.1 73M1822/73M1922 MicroDAA Software Architecture User Guide Introduction General The Teridian Semiconductor 73M1822 MicroDAATM is the world’s first single-package silicon DAA for data/fax modem and voice applications. It provides a serial MAFE (Modem Analog Front End) interface to popular DSP/host processors to implement a globally compliant low-cost soft modem solution.
73M1822/73M1922 MicroDAA Software Architecture User Guide 2 UG_1x22_057 Software Architecture Overview The software provides a framework by which a user can leverage the features of the chipset for a specific purpose. The software architecture is designed to be modular and as hardware and operating system independent as possible. Figure 1 illustrates the basic architecture model for a 73M1x22 system. The model is intended to be independent of processor and operating system.
