GA3220
Programmable Signal Processing Platform for Hearing Instruments
OVERVIEW
GA3220 is a system-in-a-package (SiP)
signal processing platform specifically
designed for hearing instruments which
require high precision processing and ultra
low power consumption. The platform
delivers high-performance audio
processing with superior power efficiency
enabling the implementation of advanced
hearing instrument algorithms such as next generation adaptive noise
reduction and environmental classification algorithms.
The GA3220 platform is comprised of three chips as illustrated in Figure1.
The GC5002 DSP chip contains both programmable instruction set DSP
cores and high performance hard-
wired co-processors. It provides
extensive computational capability
without compromising battery life.
The unique architecture of the
GC5002 simultaneously offers the
flexibility of a programmable
platform and the performance of
hard-wired design. The chip utilizes
a distributed and re-configurable
architecture which enables

hardware scalability and ensures
minimum power consumption while implementing advanced signal
processing algorithms.
The second chip, GC5055, is a programmable high fidelity audio Codec
designed specifically for digital hearing instrument applications. This chip
provides industry-standard interfaces for transducers, switches, volume
controls and programmer boxes. It also provides serial communication
ports for interfacing with third-party DSP chips and serial EEPROMs.
The GA3220 platform employs ThinSTAX鈩?advanced packaging
technology which makes it incredibly compact and suitable for CIC
instruments.
