Audio Processor for Digital Hearing Aids EZAIRO 7111 HYBRID Introduction Ezairo® 7111 is an open- programmable DSP- based hybrid specifically designed for use in high- performance hearing aid and hearing implant devices. The Ezairo 7111 hybrid includes the Ezairo 7100 System- on- Chip (So C), with its high- precision quad- core architecture that delivers 375 MIPS, without sacrificing power consumption. The highly integrated Ezairo 7100 includes an optimized, dual- Harvard CFX Digital Signal Processor (DSP) core and HEAR Configurable Accelerator signal processing engine. It also Features an Arm® Cortex®- M3 Processor Subsystem that supports various types of protocols for wireless munication. This block bines an open- programmable controller with hardware accelerators for audio coding and error correction support. Ezairo 7100 also includes a programmable Filter Engine that enables time domain filtering and supports an ultra- low- delay audio path. When bined with non- volatile memory and wireless transceivers, Ezairo 7100 forms a plete hardware platform. The Ezairo 7111 hybrid contains the Ezairo 7100 So C, 2 Mb EEPROM storage and the necessary passive ponents to directly interface with the transducers required in a hearing aid. Development Tools Ezairo Preconfigured Suite (Pre Suite)- The Ezairo Pre Suite provides a plete framework to easily develop Ezairo- based hearing aids and fitting software. Included in the Ezairo Pre Suite is a firmware bundle, configuration software, and a cross- platform Software Development Kit (SDK) to develop your own fitting software. Open- Programmable Evaluation and Development Kit (EDK) To develop your own firmware on Ezairo 7111, the Ezairo 7100 Evaluation and Development Kit (EDK) includes optimized hardware, programming interface, and a prehensive Integrated Development Environment (IDE). Note: This datasheet describes all Features of the Ezairo 7111 hybrid module. Not all of these Features are available using the Ezairo...
