3. Theory:
3.1 Ulysse
ULYSSE (HERCROM200) is a chip implementing the digital
base-band processor of a GSM mobile phone. This chip combines a
DSP M16L80 mega-module (LEAD2 CPU) with its program and data
memories, a Micro-Controller core with emulation facilities
(ARM7TDMIE) and an internal 2M-bit RAM memory, a clock squarer
cell, several-compiled single-port or 2-ports RAM and 120K
equivalent CMOS gates.
Major functions of this chip are as follows:
3.1.1
Real Time Clock (RTC)
The RTC block is an embedded RTC module fed with an external
32.768KHz Crystal. Its basic functions are:
1. Time information (seconds/minutes/hours)
2. Calendar information (Day/Month/Year/ Day of the week) up to
year 2099
3. Alarm function with interrupts (RTCINT is generated to wake up
Omega)
4. 32KHZ oscillator frequency gauging
