DSP-based SoC for hearing health solutions

One of the industry’s most integrated and power efficient single chip solutions, the Ezairo 7100 features a unique quad-core architecture constructed of a 24-bit open-programmable CFX DSP core. Supporting wireless protocols and complementing the DSP core with special error-correction and audio coding support, the SoCs incorporate an ARM Cortex-M3 processor, a HEAR configurable accelerator engine, dedicated for audio processing tasks, and a new Filter Engine  which implements efficient time-domain filters. Combined with non-volatile memory and wireless transceivers, the Ezairo 7100 forms a complete hardware platform.

“In Ezairo 7100, major signal processing capabilities are hardwired in logic blocks while the programmable DSP enables additional signal processing capabilities to be implemented in software,” comments Michel De Mey, senior director, hearing and audio solutions at ON Semiconductor.

Integrating analog front-end circuitry with an unmatched input dynamic range of 110 dB (enabling high sound precision and quality), the Ezairo 7100 series is manufactured using 65 nanometer process technology. Compatible with NFMI and RF wireless technologies, an integrated wireless controller supports efficient data transfer to and from wireless transceivers.

Michel De Mey adds: “The open architecture is designed specifically for hearing aids and hearing implant devices and allows manufacturers to respond quickly to shifting market needs.”

The Ezairo 7100 series is available as die or packaged integrated circuits.
