To ensure device and application longevity the following compatibility manifesto has been formulated more than a decade ago:
"A given Execution Architecture generation must be binary compatible for a minimum one generation backwards.
Additionally full source code compatibility for minimum two generations backwards must be ensured"
This means that for the NX32 Execution Architecture it is possible to execute binary X32 programs and with only re-compilation and no source code changes to execute LARGE architecture applications.
The RTCU Compatibility Manifesto has turned out to be a crucial element in the success of the the RTCU concept for the last 20 years - as well as for the future of the concept now transitioning into the exciting era of the Internet of Things.
