Xilinx EDK Delivers Processing Peripheral IP Cores at No Additional Cost

Widely Used Embedded Processing IP Peripherals Now Included at No Additional
Charge in the Embedded Development Kit

SAN JOSE, Calif., Jan. 15 /PRNewswire/ -- Xilinx, Inc. (Nasdaq: XLNX)
announced today that it has expanded its catalog of no-fee intellectual
property (IP) cores for designing embedded processing systems with Xilinx(R)
platform FPGAs. The 10/100 Ethernet MAC Lite, single precision floating-point
unit, industry standard UART (Universal Asynchronous Receiver/Transmitter)
16450/16550 controller and IIC (Inter-Integrated Circuit) interface IP cores
can now be licensed at no additional charge.

Made available through the Xilinx Embedded Development Kit (EDK), the four
IP cores have been ported to the enhanced on-chip CoreConnect(TM) bus
structure, the Processor Local Bus version 4.6 (PLB46) that Xilinx introduced
last November, to be implemented in designs using the award winning
MicroBlaze(TM) soft processor and the PowerPC(R) processor embedded in the
Virtex(TM) family of FPGAs.
"The EDK now includes over 40 popular cores for licensing at no charge
that can be used for a wide range of applications for PowerPC and MicroBlaze
processor systems," said Tim Erjavec, director of Embedded & DSP Marketing at
Xilinx. "Using the EDK suite of no-fee IP cores, designers can select and
build an unlimited number of configurations to meet their needs and not incur
the additional costs associated with traditional IP license agreements."
In addition to the no-fee IP cores, numerous other value-core options are
available separately from Xilinx and partners including a Tri-Mode Ethernet
MAC, USB2, CAN (Controller Area Network), and the FlexRay(TM) controller.
Peripherals for Xilinx Embedded Processing Now Available at No Charge

IP Core Part Number

IIC Interface DO-DI-IIC-SD
UART 16450/16550 DO-DI-UART-SD
10/100 Ethernet MAC Lite DO-DI-10-100-EMACLITE
Floating-Point Unit (Single Precision) DO-DI-FPU-SP

The IIC interface IP core provides an industry standard two wire,
peer-to-peer serial bus interface for device communication. This core provides
master, slave and multi-master operations, supporting 400 KHz fast mode and
100KHz standard mode. The UART 16450/16550 IP core works in both 16450 and
16550 modes and performs the parallel to serial conversion on characters
received from a CPU and serial to parallel conversion on characters received
from a microprocessor peripheral.
Optimized to provide the basic Ethernet functions with the least resources
used, the 10/100 Ethernet MAC Lite supports IEEE 802.3 Media Independent
Interface (MII) to industry standard Physical Layer (PHY) devices and
communicates to a processor via a Processor Local Bus (PLB46) interface. This
core provides interfaces for both 10 Mbps and 100 Mbps.
The MicroBlaze soft processor has an optional configuration for
implementing floating-point support via the automated Platform Studio tool
suite. By comparison, the Xilinx auxiliary processor unit (APU) floating-point
unit IP core is designed specifically for the PowerPC 405 hard processor core
implemented in the Virtex-4 FX family of FPGAs. This core provides support for
IEEE 754 floating-point arithmetic operations in single precision. Software
applications can use native PowerPC processor floating-point instructions to
achieve sustained performance of up to 100 MFLOPS (million floating-point
operations per second.)
Pricing and Availability
The no-fee IP cores are available now, delivered with the Xilinx EDK and
licensed via the online IP registration center. EDK version 9.2 is available
for US$495, and includes the MicroBlaze v7 processor core with new optional
memory management unit (MMU), Xilinx Platform Studio (XPS) 9.2 tool suite,
software drivers, documentation, and reference design examples. XPS 9.2
supports MicroBlaze and PowerPC processing design for Virtex-5, Virtex-4,
Virtex-II Pro, and Spartan(TM)-3 FGPAs. XPS 9.2 supports a broad range of
computing platforms, including Windows XP (32-bit SP1 & 2), Linux Red Hat
Enterprise (32-bit 5.0 & 4.0, 64-bit 5.0) as well as Solaris 9 (2.9/5.9). For
