Apple hides an ARM chip in the Lightning Digital AV adapter
http://avik-fidocs.blogspot.com/2013/03/apple-hides-arm-chip-in-lightning.html
...the Apple Digital Lightning AV adapter was equipped with an ARM
system chip resting inside the connector at the device end. The SoC is
complete with 256MB of RAM, which some speculate could be a decoder
for AirPlay. The secret secret was discovered by the developers at
Panic Inc. who stumbled on the chip while troubleshooting the device
in their upcoming project for video-out capabilities.
[...]
As far as Panic thinks, the chip could be a convertor or decoder with
an operating system encoded within. This OS boots up immediately when
connected, which explains the lengthy startup time for the video
output through it. The reason for doing so could be due to the
inability of raw HDMI output from the Lightning connector and the
possibility of Apple's engineers trying to reduce the cost of the
equipment with maximum functionality. Hence, someone had to think out
of the box and put this tiny computer on an external accessory - and
hence the Lightning Digital AV adapter.
The use of a tiny computer chip inside the adapter also explains the
whopping price tag of Rs 3,500 [~64 USD] for the connector alone.
