Anadigm to Demo Industry's First Analog Synthesizer Fully Integrated With Software Controls at The NAMM Show.Business Editors/High-Tech Writers CAMPBELL, Calif.--(BUSINESS WIRE)--Jan. 6, 2004 Making its first public demonstrations of audio applications for field programmable analog arrays (FPAAs), Anadigm(R) will show how its reconfigurable ICs can be used to create the industry's first analog synthesizer fully integrated with software-based controls at The NAMM Show, booth 1790, at the Anaheim Convention Center Anaheim Convention Center is a major convention center in Anaheim, California. It is located across from the Disneyland Resort on Katella Avenue. Much of the Anaheim Convention Center has been renovated in recent years with state-of-the-art facilities. , Jan. 15 through 18. A fabless semiconductor company A fabless semiconductor company specializes in the design and sale of hardware devices implemented on semiconductor chips. It achieves an advantage by outsourcing the fabrication of the devices to a specialized semiconductor manufacturer called a semiconductor foundry or "fab. headquartered in Campbell, Calif., and Crewe, U.K., Anadigm(R) provides FPAAs and associated design software that greatly reduce the time, effort, and expense required to create analog interfaces in audio, telecommunications and industrial applications. At The NAMM Show, Anadigm(R) will demonstrate a five-channel crossover filter and an analog synthesizer based on new reference designs that illustrate the power of adding software interaction to analog circuits in audio subsystems. Serving as the silicon platform for both solutions are dynamically reconfigurable FPAAs, the first analog integrated circuits for audio that can change their parameters in real time or even undergo a complete state change -- all so instantaneously as to be inaudible to even the most experienced ear. Anadigm(R)'s dynamically programmable five-channel crossover filter design will be demonstrated as applied to an active nearfield monitor system. Run under software control, its latency-free analog filters can be swept in frequency and amplitude, independently or in synchronization.

The analog synthesizer design provides true analog signaling from self-resonant oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air circuits through the filtering system to the speakers. Its twin oscillators offer a variety of waveforms over a full seven-octave range and can be mixed in a monophonic (1) Also called "mono" and "monaural," it refers to the reproduction of sound using a single channel. Contrast with stereophonic. (2) Playing only one note at a time. Contrast with polyphonic. mode or operate separately in a duophonic mode. The highly scaleable design allows a variety of filter types and audio effects to be implemented under the control of software-based LFO LFO Low Frequency Oscillator LFO Lyte Funky Ones (dance band) LFO Legal Framework Order (Pakistan) LFO Light Finding Operation (anime, Eureka seveN) LFO Last Flight Out and ADSR ADSR Attack, Decay, Sustain, Release ADSR Armoured Division Signal Regiment (UK military) ADSR Amazing Digi Scrap Race (scrapbooking competition) ADSR Advanced Digital Security Research controls, which can modulate virtually any parameter of the system, including oscillator pitch, filter frequencies, amplitudes, resonance and mark-space ratio. The design allows for plug-ins, full snapshot recovery of synthesizer synthesizer Machine that electronically generates and modifies sounds, frequently with the use of a digital computer, for use in the composition of electronic music and in live performance. settings and full MIDI interfacing to software-based sequencers. The modular FPAA approach allows the implementation of designs with multiple oscillators and audio channels. "This is the first time that a true analog synthesizer has been fully integrated with software-based controls, yet it's just one example of the endless possibilities for audio opened up by dynamically programmable FPAAs," said Brian Hodges, vice president of worldwide marketing at Anadigm(R). Using the drag-and-drop AnadigmDesigner(R)2 EDA (1) (Electronic Design Automation) Using the computer to design, lay out, verify and simulate the performance of electronic circuits on a chip or printed circuit board. software, both designs being demonstrated at The NAMM Show required less than two weeks of development work to create a first working prototype. Both run on a PCB PCB: see polychlorinated biphenyl.

A multimedia demonstration of AnadigmDesigner(R)2 v2.4 can be viewed at the Anadigm(R) Web site at www.anadigm.com. A free trial copy of AnadigmDesigner(R)2 v2.4 is available for download at http://www.anadigm.com/Down_05_a.asp. A complete evaluation kit with a development board, entry-level software, and updated documentation is now available at a promotional price of $199. Pricing for FPAA silicon starts at $4.95 in 1,000-piece quantities. About Anadigm(R) Anadigm(R) brings platform-based design to the analog world with pre-qualified software and hardware components that allow complex analog circuits to be implemented in an analog equivalent to the FPGA (Field Programmable Gate Array) A type of gate array that is programmed in the field rather than in a semiconductor fab. Containing up to hundreds of thousands of gates, there are a variety of FPGA architectures on the market. . Designed to implement signal conditioning, filtering, data acquisition, closed-loop control and other analog functions in a wide range of embedded systems, Anadigm(R) FPAAs are the first programmable analog ICs that can adapt on the fly to perform multiple functions, adjust to different environmental conditions or compensate for equipment aging. Founded in January 2000 as a venture-backed technology spinoff from Motorola, Anadigm(R) maintains its U.S. headquarters in Campbell, Calif., and European headquarters in Crewe, U.K. For further information, visit Anadigm(R) on the Web at www.anadigm.com.
