GA3219 / GA3218 / GA3217 Preliminary Data Sheet
5. Venture Overview
Venture Digital is a DSP system with adaptive algorithms that run on the
Voyageur™ hardware platform. This hardware platform is a combination of a DSP
core and a high fidelity audio CODEC. As well, thinSTAX packaging provides easy
integration into a wide range of applications from CIC to BTE.
The audio functions implemented on the CODEC include tone generation, peak
clipping and cross fading between audio paths. The DSP core implements
FRONTWAVE directional processing, programmable filters, adaptive algorithms,
compression, wideband gain, and volume control. The adaptive algorithms include
Adaptive Noise Reduction and Adaptive Feedback Cancellation. The Adaptive
Noise Reduction reduces audible noise in a low distortion manner while preserving
perceived speech levels. The Adaptive Feedback Canceller reduces acoustic
feedback while offering robust performance against pure tones. As well, Venture
contains security features to protect clients' Intellectual Property against device
cloning and software piracy.
Venture utilizes the power and capabilities of Voyageur to deliver advanced
features and enhanced performance previously unavailable to a product in its
class.
