xCORE Multicore Microcontroller Device
startKIT is based on a two-tile xCORE device (xCORE-Analog A8-DEV). Tile 0 is
dedicated to the integrated debugger and USB PHY. Tile 1 is user-programmable
providing eight logical cores with a total of 500 MIPS compute. All the digital I/O on
Tile 1 have been brought out to pins providing many combinations of peripherals
to be integrated with the startKIT board.
For information on xCORE tiles and cores see the xCORE Architecture Overview

.
The xCORE-Analog A8-DEV device is only available as part of startKIT, and is
therefore not separately documented. If you are using startKIT as a target platform
and need datasheet-level documentation, you may find it useful to review the
XS1-U16A-128-FB217 Datasheet

.
If you are using startKIT as a development platform and intend to run your final
application on a commercially available single tile device, it may be helpful to
review the XS1-A8A-64-FB96 Datasheet

Integrated debugger
The integrated debugger and associated components are positioned at one end of
the board. The debugger is accessed by the micro-USB connector connected to the
host PC, allowing the xTIMEcomposer tools to interrogate the application running
on the device using the XMOS debugger and the xSCOPE library which provides
non-intrusive program instrumentation.
See the
Power connector

and
