then continue processing its sketch (Figure 1-14). The two processors work
independently, the Bridge library facilitates communication between the two
processors.

Arduino Tre
The not-yet-released Arduino Tre promises to be a phenomenal beast. Up until
now, the fastest Arduino was the Arduino Due, based on an ARM-compatible
microcontroller. The Tre, created by Arduino and BeagleBoard, combines the
power of a full computer with the l exible input and output of an Arduino.
The Tre has a Cortex-A8 class processor, the Sitara AM335X processor, run-
ning at 1 GHz. This processor has access to 512 MB of RAM and has an HDMI
port capable of displaying Full HD (1920 x 1080). All this power is interfaced
by an Atmel ATmega32u4 using the Arduino programming environment that
enthusiasts have come to love.
Arduino Zero
The Arduino Zero is a brand new Arduino using Atmel's SAM D21 micro-
controller. It has 256 KB of l ash memory, 32 KB of RAM, and runs at 48 MHz.
The Arduino Zero is designed to handle future requirements from the Maker
community, by creating a design that is powerful, robust, and l exible enough
to be used in robotics and wearable projects, as well as the IoT. It is also the i rst
design to have an advanced debugger interface.
