22 Summary The Open OS market is growing rapidly, but so is the complexity of addressing this market Platforms with a high degree of reuse are the only means of addressing market and software complexity while maintaining quality Freescale s software architecture is specifically designed for multiple Open OS support. Not a port of an RTOS framework where the OS adaptation layer is extremely difficult to implement Each CPA Service interface (Call Control, SMS, SIM, SIM Toolkit, etc.) has been reviewed by the open OS providers and aligned with their interfaces ensuring a quick, efficient, and trouble free OS adaptation layer implementation 21
