8Technology choice key considerations
Lowest possible infrastructure cost
Lowest possible complexity ofequipment
Lowest possible implementation cost
Best coverage and capacity
Technology for high bit rates
Shortest possibletime to market
Superior spectrum efficiency
Low-risk,mature technology
Lowest possible transmission cost
Maximum service flexibility
Global acceptance of standard
9Key Market Drivers and Building a Successful
Operator Business - GSMWCDMA
- Internet access for Mobile Multimedia
- Making the 3rd generation Personal Multimedia
market a success - Cost and Timing battles - Preserving the investments - evolution from GSM
- New generation of technology - higher efficiency
and capability - Personal Multimedia/Mobile Internet access
require high quality networks with low
infrastructure and terminal cost

18Flex ASIC Issues
- Why own DSP cores?
- Vendor independence
- Own IP
- Use of STD ASIC flow
- Easy to move to another process
- Enables common mem. concept
- Configurable to particular application
- Possible to include dedicated HW and instructions
- Allow parallel execution of instructions
- Emulator support

22Summary Implementation Technology
- Relevant connection from highest system level
down to component and material level. - SOC HW without SW will be useless in the future.
- Low power means power minimization for both SW
HW - Manage future complexity
- More innovations on application specific
Architectures for mem. access and data-path - Manage future complexity
- Future systems will include electrons and
Photons(mixed)
