Introduction

Ezairo® 8310 is an open−programmable DSP−based hybrid

specifically designed for use in high−performance hearing aids and

hearables. The Ezairo 8310 hybrid includes the Ezairo 8300

System−on−Chip (SoC), onsemi’s high−end DSP processor, as well as

the LE25S161 onsemi’s ultra−low power flash memory.

Ezairo 8300 includes six programmable or semi−programmable

processing cores, providing a high degree of parallelism and

flexibility:

• The CFX is an open−programmable dual−Harvard 24 bits digital

signal processor (DSP) providing support for any type of audio signal

processing

• The ArmR CortexR−M3 processor is a 32−bit RISC processor

providing support for general processing and interfacing to external

components

• The HEAR configurable accelerator core is optimized for

pre−programmed functions that are frequently needed in audio signal

processing

• The Filter Engine allows time domain filtering and supports an

ultra−low−delay audio path

• The LPDSP32 is an open−programmable dual−Harvard 32−bit DSP

• The Neural Network Accelerator that allows the Ezairo 8300 to

perform neural network computations in a highly efficient and

flexible way.

Ezairo 8300 includes 4 ADCs with signal detection mode and two

direct digital output drivers, with high quality and ultra−low power

performances. Ezairo 8300 also includes peripherals and interfaces

needed to make it a complete hardware platform when combined with

the LE25S161 flash memory.

Ezairo 8300 also includes a Neural Network Accelerator that allows

the Ezairo 8300 to perform neural network computations is a highly

efficient and flexible way.
