Emerging Technology for Embedded Systems Software
2
Business trends

• Clear trends can be seen in the following
  domains
• Microprocessor technology
• System architecture
• Design composition
• Software content
• Programming languages
• Uml and modeling

1. Microprocessor technology
Depending on Silicon technology (eg recently
High-k). From 8-bit mc to 32-bit RISC (obsolete
for 64-bit RISC, eg Itanium). This gives a
non-restrictive array of hardware possibilities
to the designer. Because of the wide range of
available hardware, software development has to
take portability into account.

2. System Architecture
The earliest systems just had CPU and some logic
devices. Increased integration to reduce number
of chips. Multiprocessing chosen in favor of
simply incorporating more powerful
devices. Problem Multiprocessor System
debugging.

3. Design Composition
More and more design effort into software
development. Up to 80 of the total
effort. Codesign allows software to bes tested
on real hardware sooner, and allows hardware
designers to prove their design earlier.

4. Software content
Multitasking -gt RTOS More integration of
standard software components.
7
5. Programming languages
Evolution towards higher level languages. Assembl
er -gt C -gt C Java popular when runtime
reconfigurability is demanded. OO allows for
specialists to write a code without knowing the
entire system. UML modeling for high level
design.
8
6. UML
Two major uses -Code guide -Code
generation Code generation frowned upon because
each embedded system is different. xtUml
executable and translatable Uml separates
application and architecture.
