SHARC Audio Processors/SoCs
Featuring the Analog Devices SHARC® and SHARC+® digital signal processing (DSP) core technologies, the SHARC audio processor portfolio offers deterministic and very low processing latency with best-in-class MIPS/mW performance. The SHARC processor family dominates the floating-point DSP market with exceptional core and memory performance and outstanding I/O throughput. With multiple product variants and price points, SHARC brings real-time floating-point processing performance to many applications where dynamic range is key.
Many processors feature FIR/IIR hardware accelerators to offload common digital signal processing algorithms from the core, thus freeing the core to perform post-processing algorithms in parallel, making them the ideal choice for real-time audio applications. The broad SHARC+ SoC portfolio provides performance scalability up to 1GHz and a variety of on-chip memory configurations and peripheral mixes. For complex peripherals such as Ethernet and USB, some SoCs feature an integrated ARM core to handle running stack software and other microcontroller tasks.
ADSP-2156x SHARC Product Family
The ADSP-2156x audio processors are specifically targeted for applications that demand deterministic and low latency real-time audio processing including immersive 3D sound and personal audio zones, automotive active and road noise cancellation (ANC/RNC), voice-based user-interfaces and in-car communications (AEC/NR & microphone beamforming), engine sound synthesis (ESS) and electric vehicle warning sound systems (EVWSS/AVAS).


ADI LISTN EZ-AUDIO System
The ADI LISTN EZ-Audio System (EV-21562-AUTO) enables rapid tuning and deployment of a pre-configured 4-channel in/12-channel out audio flow from DSP Concepts running on the ADSP-2156x family (ADSP-21562/ADSP-21563/ADSP-21565) of SHARC audio processors. Using a custom tuning tool (AWE Tune), customers can quickly tailor the audio output for any automotive cabin. Reduce your time to audio using this turnkey hardware/software automotive audio solution jointly developed by Analog Devices and DSP Concepts.
