CAMBRIDGE, UK - Apr. 22, 2003 - ARM [(LSE:ARM);(Nasdaq:ARMHY)],
the industry's leading provider of 16/32-bit embedded RISC microprocessor
solutions, today announced at Embedded Systems Conference, San Francisco,
that it is collaborating with LSI Logic and ParthusCeva to develop a
standard Digital Signal Processing (DSP) integration specification This
specification is aimed at addressing the technical aspects surrounding the
integration of DSP cores with ARM and other microprocessor cores in
system-on-chip (SoC) designs. The specification will be announced in the
second half of 2003 and follows the earlier announcement that LSI Logic
and ParthusCeva have joined the ARM® PrimeXsys™ Community Program (see
press release… ARM
PrimeXsys Community Program Expands with Addition of DSP IP
Vendors…Apr. 14, 2003).

Digital devices of tomorrow will offer greatly advanced functionality,
combining many features into one package. Devices such as portable audio
players, mobile phones and set top boxes will bring greater design
challenges as they evolve to deliver this advanced functionality by
combining a DSP and multiple microprocessor cores in the same SoC.

This collaboration brings together two of the industry's foremost DSP
IP companies alongside ARM's leading microprocessor expertise and a number
of ARM's semiconductor design Partners, to address this challenge by
bringing commonality across the hardware and software standards that exist
for the interconnect of such cores.

As well as this collaboration on DSP and microprocessor core
integration, ARM is working independently on system-wide, on-chip
multi-core debug and trace solutions that will address and unify other SoC
technology aspects such as bus architecture, debug and real-time trace.
This solution will define how each of the elements within an SoC interact
more efficiently and will enable each element to be monitored and
optimized through one single source. This advanced debug and trace
capability will be key to the final DSP specification.

"As devices get smarter and offer new levels of functionality, the
ability to integrate microprocessor and DSP cores becomes increasingly
important," said Matthew Byatt, DSP program manager, ARM. "Integration of
these two major elements is now a serious design consideration and this
collaboration will enable us and our Partners to develop a standard DSP
integration specification that will significantly advance the capabilities
of the next generation of digital electronic-based devices."

"In a similar way that the AMBA™ methodology brought time-to-market
benefits to system interconnect, this specification will further
accelerate the time-to-market for multi-core and DSP designs," added
Byatt.

"With our leadership in the DSP licensing market, we understand fully
the design issues surrounding integration of DSPs with microprocessor
cores such as ARM technology," said Sean Mitchell, VP, Strategic
Marketing, ParthusCeva. "Coupled with ARM's leading position in the
embedded microprocessor market, our expertise in embedded DSP markets and
the expertise of the other partner in the collaboration, will enable us to
successfully develop and deliver an optimized industry standard that will
solve a major industry design problem."

"The majority of our SoC customers require a readily integrated
controller and DSP subsystem. The convergence of ARM and ZSP hardware and
software will significantly shorten time-to-market and save system
development cost," said Tuan Dao, vice president, DSP Products Division,
LSI Logic. "LSI Logic and ARM have years of experience in working together
and leading the industry in SoC and ASIC. This experience can now be
combined to offer out-of-the-box solutions of the two most critical
processing engines in integrated circuits."
