Xilinx announcement - Veronica Merryfield - May 24 14:23:00 2003

Some of you may have seen this already... At the Embedded Systems Conference this week, Xilinx (Nasdaq: XLNX)
announced the release of new advanced features for its industry-leading
MicroBlaze(TM) 32-bit soft processor core including Hardware Divide,
LocalLink, Instruction and Data caches, and a Barrel Shifter. Delivering
68 Dhrystone-MIPS at 85 MHz in the new Spartan-3(TM) FPGA, MicroBlaze
provides customers with a high-performance, low-cost processor solution
with the effective price of $1.40.

In related news, Xilinx also announced its Embedded Development Kit
(EDK) version 3.2 for designing SoC using Xilinx FPGAs. EDK(TM) version
3.2 innovates the programmable system domain by integrating embedded
hard and soft-core processors, customizable IP, and FPGA logic into a
single programmable platform. With the new version, designers can now
efficiently implement embedded systems using Xilinx Virtex-II Pro(TM)
FPGAs featuring hard embedded IBM PowerPC(TM) cores and Multi-Gigabit
Transceivers and/or a soft processor system using MicroBlaze in
Spartan-3 FPGAs.
