Introduction[edit | edit source]
As known, Android popularity is growing even in the market segments different than the consumer/mobile.
The use of Android in such applications poses tough technical challenges because the hardware platforms are not designed to be strictly compliant with the specifications defined by Google. Consequently, significant modifications to the Android Open Source Project has to be implemented in order to achieve a smartphone-like user experience, even if the underlying platform may have very few things in common with such a device.
This technical note describes one these cases and refers to a turn-key product which DAVE Embedded Systems developed for a customer manufacturing biomedical systems.
Hardware platform overview[edit | edit source]
A simplified block diagram of the hardware platform is depicted in the following image.
From the functional standpoint, the device is a sort of industrial tablet. The user interacts with a TBD" capacitive touch screen.

Simultaneous triple video output[edit | edit source]
One of the advanced features of the device is the capability to drive three video outputs simultaneously, as per customer's requirements.
Specifically, the main screen can be mirrored on the HDMI output and through a WiFi Direct connection. As the main screen resolution is 1920x1280 @ 60fps, the aggregated memory bandwidth requirement is considerable. To satisfy it, the Dual Plus version of the well-known i.MX6 system-on-chip (SOC) from NXP was chosen as the. It provides, in fact, significant enhancements over its predecessors in terms of graphics performances.
