Chapter 1: Introduction to the ML40x Embedded Processor Reference System
For new EDK users, the ML40x Embedded Processor Reference System provides an
excellent example of how the EDK tools can be used to design a full featured embedded
system consisting of hardware and software. The reference system also illustrates how to
debug designs under EDK.
References to additional information about learning to use EDK is available in

Download and installation of the IBM CoreConnect Toolkit can be useful for hardware and
systems. The CoreConnect Toolkit is only available to CoreConnect licensees. Xilinx has
simplified the process of becoming a CoreConnect licensee through Web-based
registration available at http://www.xilinx.com/coreconnect. CoreConnect licensees are
entitled to full access to the CoreConnect Toolkit including powerful bus functional
modeling, bus monitoring tools, and periodic updates. To get the most out of the
Embedded Development Kit, Xilinx recommends the use of the IBM CoreConnect Toolkit.
Reference System Information
This section is an overview of the features of the ML40x Embedded Processor Reference
System. Although the information contained in the reference system chapter is not
exhaustive, it covers the basic requirements to effectively use the MicroBlaze or PowerPC
processor.

The ML40x Embedded Processor Reference System is an example of a completely
embedded computer. It provides a wide variety of memory interfaces on three differing
buses, as well as various peripherals such as memory controllers, general purpose I/O
(GPIO), and UARTs. The example software provided with this reference system is
designed to demonstrate the system running a stand-alone application.
The Embedded Processor Reference System provides additional study of the PLB, OPB,
and DCR buses. In addition, it affords the opportunity to see how OPB-based devices are
used in a system. Step-by-step instructions are provided to help the user through the
design flow and to target a Virtex-4 device. Users can modify the ML40x Embedded
Processor Reference System to add and subtract peripherals, as well as to change the
software for their own custom-designed systems. These designs can be synthesized and
run through place-and-route to produce a bitstream for Virtex-4 devices.
