5.1.1.1 Enhanced GSM Processor

The EGSMP (ADI chip AD6426) performs all the baseband functions of the
layer 1 processing of the GSM interface. This includes all data encoding and
decoding processes as well as timing radio sub-system control functions.

In the EGSMP there is a DSP (speech codec and channel equalizer), main
processor ( Hitachi H8/300H processor) and also the interfaces ( all the sub-
system of the therminal, including the keypad, memories, display driver, SIM,
DTE and DTA data services interface and radio).
