8. Effects of device portability
Power consumption
limited computing power, low quality displays, small disks due to
limited battery capacity
CPU: power consumption ~ CV2f
• C: internal capacity, reduced by integration
• V: supply voltage, can be reduced to a certain limit
• f: clock frequency, can be reduced temporally
Loss of data
higher probability, has to be included in advance into the design
(e.g., defects, theft)
Limited user interfaces
compromise between size of fingers and portability
integration of character/voice recognition, abstract symbols
Limited memory
limited value of mass memories with moving parts

21. Mobile operating system
The main software to manage and control
hardware and software directly.
directly.
Responsible for operating the various functions
and features available in mobile devices.
Besides functioning to control the hardware
resources and software, operating system also
controls so all applications can run stable and
consistent.

Another advantage of the mobile phone OS is to
have more freedom to download additional
applications that are not provided by the phone
vendors.

23. Introduction to Symbian OS
Evolution of Symbian OS
1997 - 32 bit EPOC Platform (Psion Software Inc) – Psion Series 5 PDA
1998 – Symbian – A spin-off from Psion Software Inc.

Co-owned by Psion, Nokia, Eriksson, Motorola
Co-
The motive behind this spin-off was to develop an advanced software
spin-
platform for a new combination of consumer products called
Smartphone which would combine telephony and computing capability
1999 – EPOC named as Symbian OS
Co-owned by Psion, Nokia, Sony-Eriksson, Motorola, Matsushita
Co- Sony-
(Panasonic), Samsung and Siemens.
Symbian OS
Hard RTOS based on layered/micro-kernel architecture

Micro-kernel uses client/server session based
IPC
Servers mediate access to shared resources
and services
Kernel deals with memory allocation and IPCs

28. Win Mobile OS
Win Mobile 5.0 is a hard
RTOS
Base OS functionality is
provided by kernel which
includes process, thread,
memory and file
management
Kernel acts as a conduit for
the rest of the core OS
Win Mobile kernel uses a
paged virtual-memory system
virtual-
to manage and allocate
program memory.
The kernel also allocates
memory to the stack for each
new process or thread.

29. Memory Architecture
Windows Mobile 5.0 :
RAM is used exclusively for running
programs.
Flash memory is used for storage of
programs and data.
Result: extended battery life but slower
performance

30. Mobile Linux
The first Linux mobile phone launched by
Motorola in February 2003.
Motorola A760 series are using OS combination
of the Linux kernel software that is distributed
by Silicon Valley-based Monta Vista and other
Valley-
software from the Java programming language,
Sun Microsystems.

Linux-based operating system developed by
Google is Android.

31. Mobile Linux
Advantage & Dis-advantage
Dis-
The advantages is that Linux as an ideal OS for
mobile phones because of support by large
companies such as IBM, Oracle, and Intel. In
addition, this system value is more flexible and
offers a smaller memory and can be more
conserved.
conserved.
The disadvantage is the additional application
has not been avalaible and Linux systems built
to operate with great power, so battery resource
management is still less effective than other
OSes.

Telecommunications companies from Canada,
Reserch in Motion (RIM), to develop mobile
communications devices. Initially they are
producing products and services pager for both
directions.
