Octasic Announces High Performance Asynchronous DSP Core

Opus’ Clock-Less Architecture Provides Unprecedented Power to Performance Ratios

MONTREAL, Quebec, Canada – October 16, 2007 -- Octasic, a leading innovator of media
processing solutions, today announced its Opus DSP architecture that changes the fundamental
design of DSPs, which are the building blocks of communications equipment.

The Opus architecture solves the most pressing issue of the DSP industry, power consumption.
Building a network that can deliver on the full promise of broadband communication will require
more processing capacity in every piece of equipment. DSP manufacturers continue to pack
more and more processing capacity into DSPs to meet this challenge but the power consumed
by traditional designs is rising faster than the gains in capacity. With Opus, Octasic breaks this
barrier by delivering unprecedented power to performance ratios.

“Through its asynchronous design, Opus provides 3 times more performance per watt than
current DSP architectures on the market today,” said Doug Morrissey, Octasic CTO. “While the
DSP core construction is clock-less, to the programmer it presents a traditional processing
model. This is important to allow today’s DSP programmers to take full advantage of its
capabilities without having to be retrained to re-write and re-partition existing applications.”

Other architectures that deliver on lower power break the traditional programming model and
require a new approach to developing and coding algorithms in order to achieve the low power
benefit. Once this large investment is made in re-training programmers and re-writing code, the
customer is locked in as all these approaches are proprietary.

One of the strengths of the Opus architecture is that it maintains a traditional programming
model preserving customers’ investment in applications and skill set. The ability to achieve such
low power enables developers to leverage a multi-core DSP architecture without re-writing
code. The Opus kernel and Integrated Development Environment (IDE) provide the tools
necessary to quickly develop, test, and debug software for this high-performance DSP platform
in a predictable fashion.

Octasic’s Vocallo multi-core media gateway DSP product, also announced today (see related
release on Vocallo), is the first Octasic product based on the Opus core. Vocallo represents a
new generation of multi-core DSPs for media gateways, and is designed to allow OEMs to
develop the products they require today, with the flexibility and expandability to evolve to future
product generations.

“Opus is the key to the future of Octasic,” said Michel Laurence, Octasic CEO & Chairman of
the Board. “The Opus platform will allow us to expand into new DSP communication markets. It
combines the best power performance without compromising usability and is well suited to
leverage the full value of deep sub-micron foundry processes.”
