Cirrus Logic Expands Growing PWM Technology Portfolio Through Purchase of Advanced Patents From B&W Loudspeakers.Business Editors & High-Tech Writers AUSTIN, Texas--(BUSINESS WIRE)--Oct. 2, 2000 Cirrus Logic (company) Cirrus Logic - A manufacturer of integrated circuits including the Advanced RISC Machine and display interface processors and cards for use as Windows accelerators (requiring dedicated driver software). http://cirrus.com/. Inc. (Nasdaq:CRUS crus (krus) pl. cru´ra [L.] 1. leg (1). 2. a leglike part. crus ce´rebri ), the world's market leader in audio chips, today announced the company has purchased international patents and patents pending for Pulse Width Modulation See PWM. (PWM (Pulse Width Modulation) A modulation technique that generates variable-width pulses to represent the amplitude of an analog input signal. Like its fixed-width pulse density modulation (PDM) cousin, the output switching transistor is on more of the time for a ) technology from B&W Loudspeakers, Great Britain's leading loudspeaker company. The B&W patents will be used in conjunction with the large number of existing Cirrus Logic patents and technology advances in the company's new digital PWM line of amplifiers. The PWM technology from Cirrus Logic represents a significant advancement in Crystal(R) audio technology that reduces power requirements for audio amplifiers, dramatically improves sound quality and reduces cost and complexity of design for audio amplifier applications. Under the terms of the agreement, Cirrus Logic will own and protect PWM patents related to several fundamental components required to assure true-digital, high-performance amplifier technology. The agreement will allow Cirrus Logic to offer manufacturers a complete end-to-end solution (jargon) end-to-end solution - (E2ES) A term that suggests that the supplier of an application program or system will provide all the hardware and/or software components and resouces to meet the customer's requirement and no other supplier need be involved. Compare: turn-key solution. for designing, building and manufacturing PWM amplifiers that are smaller, more power efficient and produce a higher quality of sound than existing technology today. "Cirrus Logic is committed to offering our customers the most complete digital PWM technology available on the market and B&W's patents will help us achieve that goal," says Jason Carlson, vice president and general manager of Cirrus Logic's Consumer Products Division. "PWM amplifiers will drive the next generation of speaker technology around the world and our new digital solution, backed by these patents, will help lead the way." "B&W are delighted that Cirrus Logic will be able to make use of these patents and develop D to A (digital to analog) technology for future high-specification products," comments Dr. Peter Fryer Peter Fryer (February 18, 1927 - October 31, 2006) was an English Marxist writer and journalist. Peter Fryer joined the Young Communist League in 1942 and the Communist Party in 1945. , B&W's Research Director. "These patents originated from research into digital room optimization and although our core business is high-end loudspeakers, our research portfolio covers all aspects of audio. This is a good example of how the whole spectrum of hi-fi products can benefit." About Cirrus Logic Cirrus Logic is a premier supplier of high-performance analog and DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below).
