Similar to HAL for enabling s/w apps development on variety of h/w platforms, can a generic OS abstraction Layer ( OAL) be developed such that the apps written on top be immediately supported on all underlying platform?
IOAL can expore two interfaces. The southbound will expose open APIs towards the underlying OS ( Android/IOS/WIndows/Blackberry) which can then invoke the native APIs on OS. More than APIs the other mechanism of dealing with underlying OS will be embedded in this interface.
The northbound interface will be the standard APIs towards the APPs. This will be uniform across platforms. The OAL will also manage abstracted resources inside as it may be required to manage the underlying OS.
There will be no h/w intelligence/awareness inside this layer. This may puncture the individual power of popular platforms which draw strength from number of apps on it.
