1 Introduction
The XK-XMP-64 is a multi-core board that lets you program 64 cores with 512
threads. It comprises 16 XS1-G4 devices and two ethernet PHYs. Two banks
of 0.1” IDC connectors are provided for connecting additional components to
the XK-XMP-64. A USB cable be used to connect the XK-XMP-64 to a USB
2.0 port on a PC, providing a JTAG interface that can be used to load and de-
bug programs on the board. The XK-XMP-64 is powered from an external 12V
supply.
The power supply needs a mains cable with a standard IEC C13 connector;
each country has their own mains connectors, and you may need to acquire a
cable for your country.
To program the XK-XMP-64 you need to download a set of free Software Devel-
opment Tools from the XMOS website. The tools let you write, compile, load and
debug programs on the XK-XMP-64.
Important: You must use version 10.4 or later of the tools. If you use the
10.4 tools you must download a zip file (containing XK-XMP-64.xn) from the
XMOS website: http://www.xmos.com/xmp64—the “Tools patch”. Please
follow the instructions in Section 5when you have installed the 10.4 tools.
Demonstrations can be downloaded from the XMOS web site, including an XK-
XMP-64 tutorial which introduces the key concepts you need to understand
when programming the XK-XMP-64 board.
