“The PP5020E is a dual-core ARM processor used in some of the mid-generation Apple iPods. It can be seen that there is layout mirroring across the horizontal axis of the chip with differentiated analog circuits on the right half of the chip. This can also be observed when looking at the ARM trademark left on the die that is clearly readable in the top part but inverted in the bottom (top bottom).”
