Real-Time System Models (RTSM) enable development of software without the requirement for actual hardware. The functional behavior of the model is equivalent to real hardware from a programmers view.

Absolute timing accuracy is sacrificed to achieve fast simulated execution speed. This means that you can use a model for confirming software functionality, but you must not rely on the accuracy of cycle counts, low-level component interactions, or other hardware-specific behavior.

DS-5 includes a Cortex™-A8 RTSM that is preconfigured to boot ARM Linux.
