EZAIRO 7150 SL HYBRID Wireless-Enabled Audio Processor for Digital Hearing Aids Introduction EZAIRO® 7150 SL is an open−programmable DSP−based hybrid specifically designed for use in wirelessly connected, high−performance hearing aids and hearing implant devices. The Ezairo 7150 SL 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 7150 SL hybrid includes the nRF51822 wireless transceiver from Nordic Semiconductor. The nRF51822 is a powerful, highly flexible multi−protocol SoC ideally suited for Bluetooth® Low Energy (BLE) and 2.4 GHz ultra−low−power wireless applications. Ezairo 7150 SL also contains 2 Mb EEPROM storage and the necessary passive components to directly interface with the transducer...
