The
EGOLD+
contains a 16-bit micro-controller (µC part), a GSM analog Interface
(EGAIM), a DSP computing core (DSP part) and an interface for application-specific
switch-functions.
The µC part consists of the following:
• Micro-controller
• System interfaces for internal and external peripheries
• On-chip peripheries and memory
The Controller Firmware carries out the following functions:
• Control of the Man Machine Interface (keypad, LCD, sensing element, control of
the illumination,...)
• GSM Layer 1,2,3 /GPRS
• Control of radio part (synthesizer, AGC, AFC, Transmitter, Receiver...),
• Control of base band processing (EGAIM)
• Central operating system functions (general functions, chip select logic, HW driver,
control of mobile phones and accessories...).
