                ARC licenses technology to QLogic Corporation,
              a market leader in chips for data storage networks

Elstree, England, 31 July 2001 - ARC International plc (LSE: ARK), a leading
developer of user-customisable, high-performance microprocessors and related
intellectual property solutions, has announced today that QLogic Corp.
(NASDAQ: QLGC) has licensed ARC's industry-leading, configurable processor
technology for a new generation of storage area network infrastructure
components. ARC was chosen to provide the new embedded processor in QLogic's
devices, with the first implementation in its future iSCSI (internet SCSI)
technology products.

QLogic addresses a market need for faster data access between companies'
network servers, workstations and data storage devices, especially in the
light of the astronomical growth of data usage by large corporations and on
the Internet. Its controller chips are built directly into system
motherboards, as well as storage devices, such as disk drives, redundant array
of disks (RAID) devices, tape drives and tape libraries. The company also
produces host adapter boards that plug into computer systems and storage
subsystems, and develops the world's most innovative storage area network
(SAN) switch and switch management products.

Jerry Alston, vice president of engineering at QLogic, said, 'We have had our
own embedded processor for the past ten years. When we reviewed requirements
for our next generation products, we selected the ARCtangent-A4 for our
product line because of its small size, speed, and the development tools
available with the processor.'

The first developments to use ARC's processor will be QLogic's iSCSI line of
products. The QLogic iSCSI engineering team is currently developing this
technology for use in adapters and storage controllers to enable a new
generation of Ethernet SANs. QLogic's iSCSI solution will include innovative,
hardware-based TCP/IP acceleration for high performance SAN implementations in
Ethernet-based storage architectures.

Bob Terwilliger, President and Chief Executive Officer of ARC, said, 'We are
extremely pleased that QLogic selected ARC's processor for its new products.
ARC has achieved many successful design wins and enjoys wide application in
the network processor market. The real strength of our technology is not just
its configurable aspect, but the ability of our total package of tools and
peripheral intellectual property to match our processor to their project
requirements quickly. This enables our customers to differentiate their
products from those of their competitors at both the hardware and software
level.'

Editor's notes


 1. According to a Gartner Dataquest report entitled 'Semiconductors in the SAN
    landscape' published in April 2001, 'QLogic is the leader in unit
    shipments of Fibre Channel protocol controller chips (including hard drive
    controllers). See press release 'QLogic Leads Market in End-to-End Fibre
    Channel' issued May1, 2001 at www.qlogic.com.

 2. iSCSI technology (internet SCSI) enables Ethernet and/or TCP/IP-based SANs,
    to expand storage area networking to a broader variety of networking
    markets.

 3. Gartner Dataquest forecasts the total external storage market to grow to
    US$50.3 billion by 2004 with more than 80 percent of that storage being
    implemented in SANs.
