| Old vs New Single vs Dual
Single Engine Structure ENOS = EPOC(Symbian OS) + NOS(Nokia OS) ENOS based products -> 3650, 6600, 9210 … EPOC and NOS operate mostly independent Both operating systems are executed on the same core – they use the same common memory devices and resources CMT-APE (NOS-EPOC) communication based on Phonet protocol On execution NOS tasks have always higher priority NOS is mainly focused on cellular modem activities (RF, powers, …) EPOC is mainly focused on user interface activities
Dual Engine Structure Dual engine products –> 6630, 9500, 6680 & 6681 Both operating systems are physically separated on different cores – they have own memory devices and resources CMT-APE (NOS-EPOC) communication based on Phonet via physically bus (X-BUS) NOS is totally focused on cellular modem activities EPOC is totally focused on user interface activities

| Subject: Power Up Steps Fri May 02, 2008 1:46 am | |
| Power Up Steps After Switch On RETU activates Sleep Clock, VANA, VIO, VR1 and VDRAM Voltage @ Retu RSTX pin will then enable TAHVO ASIC TAHVO enable VCORE (RAP3G) and its internal oscillator to drive VCOREA (OMAP) VCTCXO regulator is set on and RFClk (38.4 MHz) is started by RETU regulator RETU release PURX after 16 ms after RFClk is stable 2.4 MHz SMPS clock for TAHVO is produced After PURX is released and 2 rising edge of 2.4 synchronization clock is detected, TAHVO will use it to drive VCOREA System is up and running Software is used to switch on other regulators | |

| Subject: RAP3G Fri May 02, 2008 2:06 am | |
| RAP3G
RAP3G is a 3G Radio Application Processor Successor for TIKU (used in NOKIA 7600) with some technical improvements and additional features In general RAP3G consists of three separate parts: Processor subsystem (PSS) that includes ARM926 MCU as a main processor, Lead3 PH3 DSP and related functions MCU peripherals DSP peripherals RAP3G is running with NOS and takes care of all cellular modem activities RAP3G core voltage (1.40V) is generated from TAHVO VCORE and I/O voltage (1.8V) is from RETU VIO. Core voltage in sleep mode is lowered to 1.05V | |

| Subject: Front Camera Fri May 02, 2008 2:51 am | |
| Front Camera
The front camera is controlled and its data is collected by OMAP The I/O voltage of OMAP is 1.8V, and the one of the camera is 2.8V; therefore a level shifter is needed The camera is powered with two different voltages from LDO (Low-dropout voltage) regulators: VCAM 1.5V for camera digital circuits, and sensor A/D-converter VCAM2 2.8V for camera I/O, and sensor photo diode | |
