The only thing you will find of the DigE...are the APS specifics....which do not detail the IC/PCB`s of e.Digital.
We will not know the specifics of e.Digital...until they reveal them in a patent App.....IMO...they have held off that process....once they reveal them...their secret of function is revealed....
The only commentary I lend is of APS platform specifics.
The PEA is a modified Fujitsu Laptop....running.. IMO.. an RISC processor....utilizing PCI or AGP expansion for the A/V.
