Market DemandsBusiness Constraints

• Time-to-market pressure• Price erosion• Fewer resources• Lower cost

Business Constraints

• Increased functionality• Smaller packaging• Higher reliability• Lower operations cost (power)

Market Demands

Business and Market Demands

The effective application of multicore and/or virtualization technology is necessary to address these constraints and demands

Disruptive Technologies


Multicore and Virtualization

• What are these technologies?

• What opportunities do these technologies open up?

• Why are they becoming so important in the embedded device industry now?

• What is needed to effectively apply these technologies to create better devices?


Multicore

Multicore combines two or more independent cores into a single package composed of a single integrated circuit (IC)

Does this mean your application will perform 1.6 times faster?

Drivers for Multicore and/or Virtualization

Primary Driver Technology Application

Performance • Single core to multicore• Multicore to multi-multicore

Consolidation • Multiprocessing to multicore• Multiprocessing to virtualized (single or multicore)• Multiple computers to virtualized (single or multicore)

Previous Barrier Requiring Separation• Different OS requirements (RTOS/HMI)• Specialized hardware (CPU/ASIC/FPGA)• Safe and non-safe subsystems • Secure and non-secure subsystems• GPL and non-GPL subsystems

Adoption of multicore and virtualization open up related opportunities to do the following:

• Leverage existing software in the form of legacy, commercial off-the-shelf (COTS), and open source

• Improve reliability of systems
