AUSTIN, Texas – Dec. 7, 2004 – Cirrus Logic Inc. (Nasdaq: CRUS), a premier supplier of high-performance analog, mixed-signal and digital processing solutions for consumer entertainment electronics, automotive entertainment and industrial product applications, today announced that the Consumer Electronics Association (CEA) has recognized its Intelligent Room Calibration™ (IRC) Audio Software and CobraNet™ Silicon Series as honorees in the Innovations 2005 Design and Engineering Awards program.

Cirrus Logic's IRC and CobraNet IC products were submitted in the Software/Embedded Technologies product category and judged by a panel of prominent industry designers, engineers and journalists.

"OEMS need IC companies to help them nail the right mix of features, package, and size — all at the right price point that can be brought to market quickly. In addition, chip companies also need to focus on ways to ensure the devices are consumer friendly, especially as more features are added," said David French, president and CEO, Cirrus Logic. "The two Cirrus Logic technologies recognized by the CEA illustrate Cirrus Logic's ability to provide both the silicon and software necessary to satisfy both OEMs and consumers."

Cirrus Logic's Innovations 2005 Design and Engineering award-winning products include:

• Intelligent Room Calibration Audio Software: With the introduction of advanced software into its dual-core audio digital signal processor (DSP) families, Cirrus Logic's IRC audio software enables consumers to quickly and easily attune their living room acoustics with their home theater or stereo system to replicate the rich acoustical environment of venues such as state-of-the art movie theaters, concert halls and jazz clubs. The IRC software is targeted toward mainstream audio/video receivers (AVRs) that typically sell for less than $1,000, and resolves many cumbersome set up processes associated with the limitations of the home — all within about one minute.
• CobraNet Silicon Series: With the introduction of three digital audio networking processors from its CobraNet Silicon Series of products, Cirrus Logic is making it possible for commercial and professional audio manufacturers to significantly lower the cost of deploying networked audio systems. With a single-chip approach, manufacturers now have much simpler and significantly cost-reduced solutions. This product mix ensures the right IC solution for such different market applications as ceiling speakers, mixers, power amplifiers, signal processors, intercom systems, power amplifiers and paging systems. CobraNet-enabled products can be used in a wide variety of settings including recording studios, live performances, broadcast studios and commercial "installed-sound" facilities such as office buildings, hospitals, airports, music halls, sports arenas, restaurants and houses of worship.

Cirrus Logic's CobraNet Silicon Series will be on display at Innovations Plus located in CES Central Plaza Jan. 6-9, 2005 at the International CES in Las Vegas. Cirrus Logic will also participate in Digital Experience! @ CES on Wednesday, Jan. 5, 2005, from 7:00 – 10:00 p.m. at the Bellagio.
