STRIDE Runtime
Overview
The STRIDE Runtime routes messages both within and between platform boundaries and manages the conversion of interface data as it crosses from one platform to another. This "transparent messaging" model means that your test cases can be located on one platform (e.g., as a script running off-target) and your code on another (on-target).
The STRIDE Runtime is a combination of processes and libraries that provide services for messaging, remote function calls, and tracing while providing seamless connectivity between the target application and the host operating system. The STRIDE Runtime standardizes how threads and applications communicate with each other, independent of the platform on which they are executing, which eliminates the need to integrate new software on the target hardware. Developers can then incrementally integrate embedded software on a combination of the desktop environment and the target hardware, providing more control over integration and testing. New software functionality under development can be simulated on the desktop environment while the software using this new functionality can run on the target hardware. The tremendous flexibility gained by allowing developers to choose how to integrate different software components and target platforms allows developers to detect integration and testing issues and correct defects much earlier in the development process.
The Runtime components consist of the Runtime APIs, the Runtime Thread, the PAL, the Transport Layer, and the Intercept Module. Each is briefly described here, with links provided for more detail.

The Platform Abstraction Layer Specification
The Platform Abstraction Layer, or PAL, defines the set of OS functionality required by the platform to support the STRIDE Runtime. The “pal.h” header file provided with the STRIDE installation defines the PAL functionality. The PAL also defines functionality required by the STRIDE Runtime to transmit and receive packets of data (called I-blocks) using the platform’s transport mechanism. These PAL routines enable the STRIDE Runtime to be installed on diverse environments without changing its internal design.
