Freescale Platform Components

► In MXC design one external memory part is shared by the ARM® core and StarCore® for improved memory partitioning, lower parts count, and lower BOM

► Software with low latency requirements is consolidated on to the StarCore

► CPA architecture minimizes OS adaptation layer

CPA Component Model

►The CPA component model allows clients to be distributed across multiple processors

►The CPA component model provides an OS abstraction to localize OS dependencies in to a small amount of the software

►A CPA function call library that acts as a bridge to software which is not implemented in terms of the CPA component model

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
