	7	<H1>XILINX JTAG tools on Linux without proprietary kernel modules</H1>
	8	<H2>About</H2>
	9	<P>
	10	When using <a href="http://www.xilinx.com">XILINX</a> JTAG software like Impact, Chipscope and XMD
	11	on Linux, the proprietary kernel module <i>windrvr</i> from <a href="http://www.jungo.com">Jungo</a>
	12	is needed to access the parallel- or usb-cable.
	13	As this module does not work with current linux kernel versions (> 2.6.18) a library was developed,
	14	which emulates the module in userspace and allows the tools to access the JTAG cable without the need
	15	for a proprietary kernel module.
	16	</P>
	17	<P>
	18	The library uses <a href="http://libusb.sourceforge.net/">libusb</a> to access USB devices and the
	19	<a href="http://people.redhat.com/twaugh/parport/html/x623.html">ppdev</a> interface to communicate
	20	with parallel cables. The parallel part currently only supports Parallel Cable III mode (and PCIV in
	21	PCIII compatibility mode) as the faster PCIV modes use another kernel module which is not emulated by
	22	this library. So you are limited to a 200kHz JTAG clock when using Parallel Cable IV with this software.
	23	The USB cable is supported at full speed.
	24	</P>
	25	<P>
	26	Experimental support for FTDI 2232 based devices has been added. They are seen by Impact as a Parallel
	27	Cable III. These devices are currently significantly slower than every other supported cable.
	28	</P>
	29	<P>
	30	The library is called <i>libusb-driver</i> as it was developed to support the USB cable, but later
	31	extended to also support parallel cables.
