EZAIRO 7111 HYBRID Audio Processor for Digital Hearing Aids
■ 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 (SoC), 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 communication. This block combines 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 combined with non−volatile memory and wireless transceivers, Ezairo 7100 forms a complete hardware platform.
■ The Ezairo 7111 hybrid contains the Ezairo 7100 SoC, 2 Mb EEPROM storage and the necessary passive components to directly interface with the transducers required in a hearing aid.
