ADSP-2184x/SC84x Series Extends ADI’s Audio Processing Leadership

1.2 GHz SHARC-FX Core Offers 5x the Audio Processing Power vs 1.0 GHz SHARC+ Core
Doubles Arm® Performance and On-Chip Memory vs ADSP-SC598 Predecessor

The ADSP-2184x/SC84x (ADSP-21844 / 21846 / SC844 / SC846) series of processors are designed to provide immersive audio and sound experience in automotive and consumer/pro-audio applications, as these audio processors are specifically targeted for applications that demand deterministic and low-latency real-time audio processing. When used in combination with the A²B 2.0 Automotive Audio Bus technology, the resulting system delivers premium sound and a truly immersive audio experience. To facilitate integration, Analog Devices also offers ADI LISTN^® software supporting applications such as immersive 3D sound and personal sound zones (PSZ), automotive active and road noise cancellation (ANC/RNC), voice-based user-interfaces and in-car communications (AEC/NR & microphone beamforming), and engine sound synthesis (ESS) and electric vehicle warning sound systems (EVWSS/AVAS). These audio processors are also excellent for use in Home Theater and Gaming, as well as Unified Communications (UC) and ProAV applications.

Analog Devices has partnered with DSP Concepts to optimize the Audio Weaver® core libraries specifically for the SHARC-FX DSP core, leveraging the high-performance on-chip FIR/IIR hardware accelerators wherever possible, resulting in even more processing power. Audio Weaver contains tools that facilitate development from prototype to production. It is a low-code audio platform that streamlines automotive audio development and reduces risk and complexity by utilizing a drag-and-drop host application for product design, paired with an audio processing engine embedded in the DSP.

The ADSP-2184x/SC84x family are single-SHARC-FX DSP core floating-point processors, combining flexible audio connectivity and performance scalability across a number of pin-compatible products with several on-chip memory options providing scalability from 2400-4900 SHARC+ MIPS. The ADSP-SC84x processors also integrate dual Arm® Cortex®-A55 (7200 DMIPS at 1.2 GHz) cores, providing a control processor for enhanced integrated peripherals including Gigabit Ethernet (w/AVB), USB 2.0 HS OTG, 3-pin MLB, and CAN-FD and the capability to run operating systems such as Linux.

ADI’s software development tools enable solution developers to achieve fast time to market. Optimized software-based audio algorithms can be tuned for specific use cases for ease of solution design and reduced development effort.

The ADSP-2184x/SC84x processors are available in a 484-ball FCBGA (18mm x 18mm, 0.8mm pitch) package in both automotive and consumer grades to provide design flexibility and enable thermally efficient compact designs across operating temperature range.
