DSP-Based System-on-Chip for Hearing Health Solutions
ON Semiconductor has launched the Ezairo 7100 series of integrated circuits and packaged hybrids for advanced hearing aids and hearing implant devices. With five times the processing power of previous systems, the system-on-chip (SoC) provides built-in flexibility to support evolving algorithm, wireless and system-level needs.
Ezairo 7100 is one of the industry’s most integrated and power efficient single chip solutions. Its unique quad-core architecture is constructed of a 24-bit open-programmable CFX DSP core. Inclusion of the ARM Cortex-M3 processor supports wireless protocols and complements the DSP core with special error-correction and audio coding support. The system also features a HEAR configurable accelerator engine, dedicated for audio processing tasks, and a new Filter Engine which implements efficient time-domain filters. When combined with non-volatile memory and wireless transceivers, it forms a complete hardware platform.
